White-tailed spiders and Wolf spiders have long been blamed for necrotizing arachnidism. This is a condition where ulcerative lesions around a bite sitre can eat away at the tissue until bone is exposed. Recent studies suggest that the white tailed spider may have been wrongly accused.
Bites from the white-tailed spiders are common because they inhabit houses and are frequently found in living areas and bedrooms. They can bite readily if threatened but the venom is weak (on biochemical analysis) and any undesirable effects are short lived. The wolf spider, however, lives in the soil outside and has been responsible for bites that have developed into necrotizing arachnidism.
The culprit is not actually the spiders venom but a bacterium on the spiders fangs called mycobacterium ulcerans. The bacterium can be found in the soil and infects people when they are bitten by the spider. So, the spider is actually just a mode of transport carrying the nasty bacteria into the flesh of victims. Any spider living in the soil could, therefore be a vector of transmission. White-tailed and huntsmen spiders are found mainly indoors but can be found outdoors under the bark of trees and under rocks.
There is a species of funnel web spider found only in the dandenong ranges. Fortunately, it is not as deadly as its Sydney relative. However, it may pose problems for cats, dogs and infants. Symptoms of evenomation include intense pain at the bite site, swelling, headaches, nausea and dizziness. Sometimes, muscle tremors and vomiting can occur. Funnel webs build funnel shaped covered webs over visible holes in the ground. They have large fangs and large black bodies. Their ground holes are commonly seen but the spider itself is rarely sighted.

Urine test kits are available for dogs and cats to detect very early damage to kidneys.
Using less than 2ml of urine, trace quantities of blood product (microalbumin) can be detected. This is an indicator of kidney damage, long before there are elevations of kidney enzymes in the blood. Positive results can also be an indicator of other systemic diseases.
This test is particularly useful in cats and dogs that are at risk of kidney diseaseThese include animals over 7yrs of age, as well as young purebred long-haired or Burmese cats (at risk of inherited cystic kidney disease).
It is also a useful screening test for any animal prior to having an anaesthetic or suffering from other illnesses, such as pancreatitis and liver disease.
If early kidney damage is detected, preventative measures can be ins
tigated to minimise the deterioration of the kidneys or reverse the effects of minor damage. This includes the use of special low phosphorus/protein or prescription diets, antibiotics, phosphorus binding medications, diuretics, anabolics, etc.
These tests can be done in the clinic and only take 5 min. For more information, please contact the clinic or ask one of our staff at your next visit.
Dental disease is extremely common in dogs, cats and horses. As many of 70% of cats are estimated to have dental problems and nearly as much in dogs. The disease process in dogs and cats begins with bacteria in the mouth laying a template for plaque to form. Layers of plaque become cement like (tartar) and appear as yellow-brown or black deposits (which are painful) on the surface of the teeth. If this is left untreated, tartar can progress to gum retraction, loose teeth and abcessation.
Other major complications that can arise from dental health include heart valve plaques, septicaemia, pneumonia, kidney, liver and brain disease.
Special pet toothpaste must be used but normal tooth brushes or finger brushes can be used. (We do it for our own teeth so why not do it for our pets?
If your pet can tolerate them (not recommended for some small breed dogs prone to pancreatitis or gastroenteritis). The Australian Veterinary Association after an extensive review of pet dietary requirements, recommends feeding RAW bones at least 3 times a week (in conjunction with a nutritionally complete diet like a premium pet food).
Prescription food like Hills t/d is a nutritionally complete premium dry food that has all the nutritional parts on the outside with a hard core inside. Since the kibbles are quite large, the dog/cat must chew them up to swallow and in the process cleans its teeth. Recommended for uncooperative pets that wont allow brushing of the teeth and those pets that can’t tolerate bones.
Ultrasonic scaling and polishing of the teeth under general anaesthetic is required to return good oral health and prevention of recurrence can begin. For those pets that have a particular recurring problem we have introduced low cost dentals. Only for those pets with first stage dental disease (minor plaque & tartar) - starting from $150 all inclusive of the anesthetic, hospitalization, antibiotic & pain killer injections for small dogs).
The ticks commonly found around the Dandenong Ranges are related to the paralysis tick found in coastal areas but don’t seem to cause any life threatening paralysis. Mostly, it is the tiny larval stage ticks that cause intense irritation to small dogs and cats.
The areas where the larval ticks usually attach are inside the front legs, under the belly and under the armpit regions. They appear as small scabs where the ticks have left craters in the skin.
Adult ticks can be removed with special tick hooks or killed with methylated spirits or medicated washes and spot-ons. Ask our trained vet nurses for the right treatment products or for advice on removal.
Some snail baits, esp older ones contain a severe toxin called metaldehyde. This poison acts on the brain, central nervous system, liver and respiratory system. Unlike rat bait poisonings, signs of toxicity occur immediately after eating the poison or can be delayed up to 3-4 hours.
Symptoms of poisoning include excess drooling, wobbliness, muscle tremors, convulsions and increased sensitivity to touch, sight and sounds. Coma and death follow within 4-24 hours after eating the bait if treatment is not given immediately.
Diagnosis is usually made by seeing the blue/green granules in the animals mouth or vomit, clinical signs and extremely high liver enzymes on our blood analyser.
Unlike rat bait poisoning, there is no antidote. Treatment is aimed at getting the poison out of the system as quickly as possible before permanent damage is done or death occurs. This is done by giving an anaesthetic and pumping out the gut contents and by enemas and i/v fluids/diuretics and liver protectants. Unlike rat bait toxin, once the animal recovers, there is usually no ongoing treatemtn unless the liver is severely damaged.
Animals can still die days after ingestion of poison from liver failure.
Often people will ask us if it is safe to feed chocolate to dogs. Generally it is NOT recommended to feed chocolate to dogs and cats. The poisonous chemical in chocolate is called theobromine and its toxicity depends on the type of chocolate and the size of the dog that eats it.
The type of chocolate that is most dangerous is unsweetened baking chocolate and cocoa powder. Other types containing high levels of theobromine are dark chocolate and semi-sweet chocolate. Lower levels of the toxin are found in sweetened milk chocolate, other candy/lollies and rarelyin landscaping containing cacao shells. White chocolate contains negligible amounts of theobromine.
The symptoms of toxicity include increased blood pressure, heart rate and rhythm interference, nervousness, excitability, tremors, panting seizures, urinary incontinence, coma and death.
Treatment is supportive and the goal is to remove the chocolate from the body as soon as possible to reduce the toxic effects. This involves induction of vomiting then rigorous lavage of the stomach and intestines under general anaesthesia. Activated charcoal will help reduce absorption in the gut and intravenous fluid therapy can help dilute the toxin in the body and help promote excretion of it. There is no antidote. Heart drugs may be needed to prevent life-threatening dysrhythmias.
Certain breeds are more susceptible than others. Those breeds with short noses and squashed upper airways like bulldogs, pugs and boxers are most at risk. There has been a report of a british bulldog in england that collpased and died within minutes of eating only spilt crumbs from the owners chocolate energy bar.
Most pet poisonings are the result of careless placement of baits, overuse of baits or failure to dispose of posoned rodents or old baits.
There are 2 types of baits but both have a similar action ie to destroy/inhibit clotting factors in the blood. The result is that the poisoned animal bleeds to death, usually over a period of a few days to 2 weeks.
Dogs and cats can seem fine for days before the liver reserve of clotting factors(vitamin K) becomes depleted. After this just normal activities like running, playing, eating or sneezing /coughing can cause minor bleeds that continues unchecked until the animal starts to run out of blood.
Initially signs of coughing, mouth bleeds or dark coloured faeces may be present. This progresses to pale gums, lethargy and eventually collapse and death. Sometimes an owner may find an animal dead aithout noticing any signs of apparent illness.
Treatment consists of vitamin K supplementation for a period of 1-8 weeks or longer depending on the type of bait. It is very improtant if possible to let the vet know what type of bait was eaten (eg talon, talon G, ratsak etc) as this will give us an indication of how long treatment must continue. A huge misconception is that once the pet survives the initial insult that they should be OK.
Pets can still die as long as 4-6 weeks after eating the poison eps. If treatment is stopped because the pet seems to be running around like normal. Blood clotting test will need to be done once treatment stops to ensure that the pet is able to produce their own clotting factors again. In severe cases, whole blood transfusions, treatment for shock, oxygen and hospitalisation may be needed.
Arthritis, also known as degenerative joint disease (DJD) is a progressive and permanent deterioration of the articular cartilage in joints.
Just like humans, dogs commonly suffer from arthritis. This condition can affect more than one in five dogs and occurs due to the cumulative effect of abnormal stressors placed on the joints. These abnormal stressors are usually due to abnormal alignment of the bones, trauma, ageing or obesity as the joint must carry a larger load than it is supposed to.
Clinical signs of arthritis may include any of the following: reluctance to walk, climb stairs, jump or play, limping, lagging behind on walks, difficulty rising from a rest position, yelping in pain when touched, personality changes, appetite change (inappetant or obsessed with food).
In order to correctly make a diagnosis of arthritis a full musculoskeletal examination must first be done to rule out any other causes of lameness or lethargy (eg. pancreatitis, liver disease, infections or fractures). This includes palpation of all muscles, bones and joints as well as specific tests to look for laxity of tendons and ligaments.
X-rays should also be done and these can give important information about which joints are effected and how far the disease has progressed. From this information, we know what treatments should be instituted to give the best results.
There are several treatment options available for arthritis, these include non-steroidal anti-inflammatory drugs (to reduce pain & inflammation & slow down the progression of the joint degradation), pentosan / cartrophen / synovan / zydax injections (increase joint fluid production & help restore cartilage within the joint), natural supplements such as glucosamines & chondroitin (Sasha's Blend, Seaflex treats, PAW Osteosupport treats, Joint Guard, Pernease powder, etc), weight loss (one of the MOST important factors to regulate to help treat arthritis), padded but supportive bedding and regular, gentle exercise. A fantastic diet is available called Hills j/d. This is a prescription diet containing a unique fatty acid (EPA) that modifies the genes to block the enzyme causing cartilage degradation. Many dogs experience significant pain relief whilst on this diet. In-clinic use of STEM CELLS can sometimes be used as another treatment option for dogs with advanced arthritis. This involves harvesting stem cells from the dog's own body fat then activatinig them & injecting them into the affected arthritic joints. The draw back is the long anaesthetic required for these patients (particularly in older pets). Long term improvement hasn't always been seen with this method of treatment.
Class 4 laser therapy is a new treatment modality that has been showing promising outcomes / relief against the pain of arthritis with regular treatments. The laser penetrates deep into tissue to stimulate blood supply & help repair tissue & reduce scarring. It can be used post operatively around wounds or as regular therapy for osteoarthritis. It is also shows promising results when used to treat ear infections & non-healing wounds.
Shorter, more regular exercise / walks are advised for arthritic animals. Avoid ball chasing, stairs & jumping as this can lead to very sore joints later after the exercise has completed & the dog is resting. Ramps or stategically positioned furniture may be needed to help arthritic cats get up high onto surfaces. Putting the food & water bowls onto a step or raised platform can help reduce pain in pets that have arthritis in their spine / neck. Swimming is great exercise for arthritic pets but don't overdo it & ensure your pet can get into & out of the water easily.
Tips on preventing thunderstorm and fireworks phobias:
All dogs should be vaccinated against Parvovirus, Hepatitis and Distemper. Puppies need a program to minimise the risk of them contracting these potentially fatal viruses as well as the less deadly Canine Cough. At D.R.V.C. we also vaccinate puppies against Coronavirus (a serious diarrhoea virus) and Leptospirosis (C2 vaccine). The recommended vaccination program is:
An annual booster is required every year thereafter. A C5 is the advised adult vaccination as it offers protection against Canine Cough (Parainfluenza and Bordatella.) which is highly infectious.
Dogs need to be wormed regularly to remove intestinal worms. These include whipworm, round worm, hookworm and tapeworm. Worming should be done from:
Supermarket wormers are not 100% effective
Heartworm is transmitted by mosquitoes and is present in many areas of Australia. Your puppy should begin heartworm prevention by 6 months of age. If your puppy is overdue for a dose by 6 weeks then a blood test is advised before resuming prevention. Most heartworm products are administered monthly, however there is now a convenient yearly injection for adults.
It is important to de-flea your pup. Fleas carry tapeworm, and can even cause anaemia. Most flea treatments are administered monthly by topical application. There are a variety of extremely safe products that can incorporate heartworm, flea, mange and ticks.
Most people are aware that we shouldn’t feed our dogs chocolate, but did you also know that grapes can be poisonous to dogs? Of course, we all know that rat bait and snail bait is very dangerous, but were you aware that some lilies can cause damage to a cat’s kidneys? Here is a list of some common household toxins that pet owners should be aware of:
Toxic component is Theobromine (found at highest levels in cooking chocolate and dark chocolate).
Symptoms: Vomiting, restlessness, anxiety, fast heart rate. Can progress to seizures and heart problems. Large amounts are usually required to cause toxicity (e.g. a family block / 5kg dog)
Toxic component is unknown and not all dogs are affected.
Symptoms: Causes acute kidney failure. Dogs will often vomit after eating them.
Approximately 1 nut/kg is considered a toxic dose.
Symptoms: Hindlimb weakness, depression, vomiting, tremors, abdominal pain and fever.
Ingestion of sea water while swimming is the most common cause.
Symptoms: Vomiting and diarrhea, can progress to more severe abnormalities such as depression and seizures, especially if access to fresh water is limited.
Toxicity can occur after oral intake or skin exposure.
Symptoms: Vomiting, diarrhoea, depression (following oral intake). Weakness, muscle tremors, depression, walking and behavioural abnormalities (following skin exposure).
Of course there are other more well-known toxins that can harm our pets as well (e.g. snailbait, anti-freeze, rat bait). Being aware of toxins and preventing access by your pet will help to avoid any potential problems. If your pet does happen to ingest anything that may be toxic, please call 9751 2999 (24hrs) so that our vets can advise you on the best treatment for your pet.

Springtime heralds the start of itching, scratching, biting & licking for a lot of dogs and cats.
The most common causes of these symptoms at this time of year are flea bites, flea allergies, contact allergies, inhaled allergens & larval ticks. Food allergies can cause itching all year round as can allergies to dust mites & sarcoptes mange mites. Some dogs are allergic to numerous things & have a condition called atopy.
There are many treatments that can alleviate allergic itching but the only cure is to establish the exact cause of the allergy & prevent access to it completely. Treatments include cortisone, anit-histamines, omega fatty acids, alpha keri oil, cyclosporin, antibiotics, special flea/tick treatments, topical creams, de-sensitising vaccines and special sensitive skin diet foods. If your dog, cat, horse or other pet has persistent itchiness or recurrent ear/eye/skin infections call us for a step by step plan to recovery.
Dogs love a good run off the lead. The following areas are approved for dogs off-lead:

Feline AIDS is a virus caused by infection with feline immunodeficiency virus (FIV). This virus, like the human form (HIV), interferes with the immune system of the cat, making it unable to fight harmful infections.
FIV is most commonly spread by biting, as the virus is shed in high levels in saliva. The spread of FIV through grooming, sharing water bowls, or from a mother to her unborn foetus is extremely unlikely.
Cats infected with FIV may remain healthy for up to 10 years. While some infected cats will show no signs of FIV, others may have symptoms such as:
In Victoria research has shown that approximately 26% of cats test positive to FIV.
Vaccination is the best way to prevent the spread of FIV as there is no cure or treatment. Cats require 3 initial doses of the FIV vaccine (at 2-4 weekly intervals), then an annual booster. FIV vaccine can be given to kittens from 8 weeks of age, this can be done with their normal vaccinations for feline respiratory diseases and feline enteritis.
Although feline immunodeficiency virus is related to the human form (HIV), no human has ever been reported to be infected with FIV.
