Skin issues are one of the most common reasons for taking pets to the vet.
Skin problems is a wide subject and these cases can be complicated and challenging for the vet. Having a skin problem often suggests the existence of an underlying problem in the body, usually not even directly related to the skin itself.
One of the more straightforward skin diseases is ringworm infection, which is not, as its name suggests, caused by a worm, but by a fungal infection.
The fungi responsible for the infection are known as dermatophytes.
In animals, the classic ringworm lesions are patchy areas of hair loss and scaliness, usually with very little inflammation or redness. It is not usually itchy. The lesion can be solitary.
A case of of multiple lesions is considered systemic and is called generalized dermatophytosis.
The disease is highly contagious. The disease transmission occurs through direct or indirect contact with an infected animal. Indirect contact means contracting the disease by touching objects that the infected animal has touched; such as bedding, brushes or grooming equipment, furniture, rugs, etc.
Human can also get infected with ringworm by getting in contact with an animal that carries the fungi.
All animal are susceptible to ringworm infection. Among household pets, the disease is most common in cats. Infected dogs generally have a skin lesion at the site of the infection.
Interestingly though, not all cats that carry the fungi will show signs of skin lesions. Cats can be “silent carriers” and spread the disease without suffering from it. Not every animal or human who touches infected animals or objects will become infected.
The disease development depends on one’s age, immune status, skin condition and grooming habits. All these influence the fungus' ability to grow and infect.
In both animals and humans, young, elderly and those with a compromised immune system for any reason, are most susceptible to the infection.
Despite the fact that the disease is transmissible from pets to humans, this is not a reason to get rid of your pet. Ringworm is a treatable condition in both animals and humans.
The diagnosis for ringworm in animals is fairly simple. In about 30 per cent of the cases, looking on the lesion with a special ultraviolet light (also called wood’s lamp) in a dark room, will show a typical green fluorescence. Ringworm confirmation is done by a culture.
The veterinarian collects a sample of hair and scales from the lesion and places it in a special, small jar known as the culture media. Placing the jar in a dark place and the culture media provide the optimal condition for the fungus to grow and thrive.
This test is very easy to perform. It is affordable, non invasive, and does not require anesthesia or sedation. The only disadvantage of this test is that the results are not given immediately.
It can take for the fungal colonies up to 21 days to develop, even though, from my personal experience, usually within 5-7 days we get a good idea if the result is positive.
If the lesion is solitary, the infection may be self limiting and may eventually disappear without treatment. Generalized cases (multiple lesions) require treatment.
The treatment can be done topically in a form of a medicated shampoo. Some cases require systemic treatment by oral medication.
Your veterinarian can guide you through which course of action is best recommended for your pet’s condition.
Gathering information about your pet, and the physical exam findings will also help your veterinarian in assessing whether the condition has developed due to other underlying problem that has weakened your pet’s immune system.
If you recognize in your pet a single or multiple areas of hair loss, with or without crusting and scaling that are usually not itchy, take it to be examined by your vet.
If your pet was diagnosed with a ringworm infection, thorough cleaning of the house and the dog’s bedding and equipment is also necessary for the elimination and prevention of reinfection.
Also consult your GP about treating the human members of the family.

Christmas holiday is upon us. In the season of giving, chocolate is a popular gift.
As a chocolate lover, I know how a chocolate can raise your spirit. As well as most people, dogs tend to have a “sweet tooth” too, but for our canine friends, chocolate in large amount is harmful, even fatal.
Chocolate is made from cacao beans, which contain a toxic substance called theobromine.
Cacao beans also contain caffeine, but in much smaller amounts than theobromine. Both theobromine and caffeine are members of a drug class called methylxanines.
Theobromine is toxic for dogs because they process it much more slowly than humans. Seventeen hours after eating chocolate, half of the theobromine is still in the dog’s system.
Theobromine is also toxic to cats, however, cats are less likely to ingest chocolate than dogs.
Theobromine and caffeine can adversely affect the nervous system, and the heart. They can also lead to increase of the blood pressure.
The early signs of chocolate intoxication are nausea (manifested by drooling and smacking the lips) vomiting, and excessive urination.
Truly toxic amounts can induce hyperactivity, rapid heart rate, tremors, seizures and eventually respiratory failure and cardiac arrest.
The more theobromine a cocoa product contains, the more poisonous it is to your dog.
Researches showed that one ounce of milk chocolate per pound of body weight is potentially lethal.
Dark chocolate and baker’s chocolate are riskiest, milk and white chocolate pose a much less serious risk.
Twenty ounces of milk chocolate, 10 ounces of semi-sweet chocolate, and just 2.25 ounces of baking chocolate could potentially kill a 22-pound dog.
Small dogs are at greater risk of chocolate toxicity than large dogs because they can be poisoned by small quantities of chocolate.
In most instances, diagnosis is based upon physical exam findings in combination with a history of access to chocolate. There is no definitive test for chocolate ingestion.
Unfortunately, theobromine has no antidote. The treatment for chocolate toxicity is primarily supportive.
Treatment focuses on addressing symptoms and problems that develop until the toxins are excreted by the body.
In most cases, intoxication resolves within 24-36 hours.
If the dog was presented shortly after the ingestion, attempts to reduce the poison absorption can be made by inducing vomiting or feeding active charcoal. Intravenous fluids and anti seizure medication are also frequently required.
Symptoms of intoxication usually occur four to 24 hours after ingestion.
Prevention is the key. Keep all chocolate goodies in a non-accessible place for your pet. Don’t share any chocolate with your pet on any circumstances; not even on its birthday.
If you suspect that your dog got exposed to chocolate, contact your veterinarian.
The dog’s weight, the type and amount of the chocolate ingested are all important information for the vet, in order to assess the dog’s risk and condition.
The holiday season is a wonderful time for families to spend time together and connect.
Paying attention to your gluttonous pet’s eating is a one sure way of keeping you joyful and away from the vet’s office.

Dogs are known as man’s best friends, but their place in the family has changed.
It used to be common to keep the dog outside, even it was a companion and not a guard dog.
Nowadays, it's much more common to keep the dog indoors.
In fact, many dog owners are welcoming their dog into their beds, and I get asked quite often whether this is recommended.
Whether dogs should sleep with their owners is a personal choice, but there are pros and cons.
The bond between a human and a dog can be potentially even stronger than the bond between human beings.
Your dog doesn't judge you. Your dog loves you unconditionally, and always will. It’s a bond you can trust and rely on.
Many people find the physical presence of their dog in their bed soothing and a source of security.
The problems that can arise from sleeping with a pet are divided — behavioral aspects, and medical aspects for both owner and dog.
When it comes to aggressive dogs, dominant dogs or young dogs still being trained, sleeping with their owner can blur the boundaries for the dog.
In a healthy relationship between a dog and its owner, it is clear that the owner is the alpha (the leader), that the owner is in charge and sets the tone.
If the dog is allowed into the owner’s bed, it may confuse it and send mixed messages. Having its own bed, and sometimes even sleeping in a crate, is required for some dogs in order to establish this hierarchy.
As for the medical aspect of the owners: clearly, the biggest issue is hygiene.
Dogs walking outside bare paws may step in urine, feces or any other contaminated surface.
If you let your dog into the bed, it's recommended to minimally clean the it’s paws before allowing it into the bed.
One should also be mindful for external parasites such as ticks, fleas, or lice, which can also infest humans. The parasites are not found only on the dog, they may also be present anywhere in its environment.
Letting your dog sleep in your bed increases your chance of getting exposed and the potential infestation by these parasites.
Dogs that are commonly taken on hikes, camping and have an abundant access to the outdoors, as well as dogs that spend time in doggy daycares, grooming facilities or any other place that they can come in contact with other pets, can get by these external parasites.
If your dog is infested by external parasite, it’s an easy fix when it comes to the dog.
There are a wide variety of recommended veterinary pest control products. One must know that a crucial part of the parasites extermination is by sterilizing the entire dog’s environment including all the house and bedding.
Some dogs are very sensitive and prone to allergies. The laundry detergent and softeners that people use can be a source of a severe contact dermatitis (allergy that causes severe skin inflammation).
A special hazard concerning small dogs can arise from the dog jumping off the bed, or falling off the bed. Especially if the mattress is very thick, which makes the bed very high.
I’ve witnessed dozens of leg fractures and knees ligament tearing because of a bad fall of the bed.
There is no one right answer to the question whether your dog should sleep in your bed.
It is a personal choice that depends on a few factors:
- the type of dog
- its personality
- your family lifestyle and activities that can potentially expose the dog to some unwanted invitees
- the type of bond you are choosing to have with your pet.
If you choose to welcome your dog into your bed, take some precautionary measures such as keeping your pet up to date on his pest control and deworming, and make sure the dog has a safe way of getting off the bed without risking an injury.
If you want your dog close, but not necessarily in your bed, place its bed near your bed, which may be the best compromise for all.

We are all so lucky to live in a paradise like the Okanagan.
We get to enjoy the best of the best that the valley has to offer. Your pet would absolutely love to join you to any activity in the sun. Even if the pet stays behind at home and is kept outside the house, it is important to remember pets should be protected from the sun and prolonged exposure to hot temperature that can lead to heat stroke.
Heat stroke occurs when the body is exposed to high temperature or humidity over a long period of time. The heat-regulating mechanisms of the body are unable to effectively deal with the heat, causing the body temperature to climb uncontrollably.
Young and old animals are more sensitive to high temperatures, as well as heavy coated pets and short snouts animals such as pug, shih tzu, boxers, Pekinese, bulldogs and Persian cats.
Heat stroke is considered when the body temperature is generally higher than 40 C or 104 F.
The high body temperature affects cellular activity of all internal organs and is a life-threatening condition.
The symptoms start by heavy panting and drooling, vomiting and diarrhea, weakness and confusion.
As the heat prostration progresses. the gums become dry due to dehydration, and vomit and diarrhea may become bloody.
Terminal stages are manifested by seizures or coma, shallow breathing or absence of breathing effort and finally death.
Heat stroke is an emergency condition that requires an immediate medical care.
If your pet is showing signs of heat stroke, transfer it immediately to a cool, shaded spot, pour cool, but not icy, water on your pet. You can pour alcohol on your pet paws. Alcohol dilates blood vessels, which is helpful in cooling down the body.
First aid is crucial in the first minutes heat stroke, however your pet’s well being should not stop there.
Your pet should be checked by a veterinarian as other medical problems (kidney failure, heart, neurological, intestinal problems) could arise hours or even days following a heat stroke.
Prevention is the key. Here are few tips how to keep your pet safe.
Pets should stay well hydrated when travelling or hanging out in the outdoors. Don’t forget to bring along water for your pets.
Do not encourage your dog to run and play outside in the hot hours of the day, exercise your dog in the early morning or evening hours.
Make sure your pet has a shady place to rest at. It is very important to remember not to leave pets in cars greenhouses or similar hot environments.
Leaving a pet in the car in the hot day, even with a cracked open window can be deadly even just after few minutes.
When you are taking your dog to the lake, don’t assume that they are hydrated just for the fact that they are in the water. Supply drinking water for them.
I hope you’ll enjoy the summer with your pet, keep everybody safe and cool and away from the vet’s office.
