Canine Parvovirus

Canine Parvovirus is a highly contagious viral disease that primarily affects puppies and unvaccinated dogs. It can be transmitted through exposure to infected dogs or contaminated objects. The mortality rate for dogs diagnosed with Canine Parvovirus is high, making it crucial to take preventive measures. Vaccination is the most effective way to protect your dog from Canine Parvovirus. Keeping your dog's environment clean, practicing proper hygiene, and using flea and tick control methods are also important for prevention. If your dog shows symptoms such as vomiting, diarrhea, or lethargy, seek immediate veterinary attention. Remember, early detection and treatment can significantly increase the chances of survival. Pro Tip: Regularly vaccinate your dog against Canine Parvovirus to ensure their protection.


Distemper is a highly contagious virus that affects dogs. It is transmitted through respiratory secretions. Recognizing the signs and symptoms of distemper is crucial for early detection and treatment. Here are key points to know about distemper:

Distemper is a serious disease with potentially fatal consequences.
Common symptoms of distemper include respiratory problems, fever, nasal discharge, coughing, and eye discharge.
Dogs that survive distemper may suffer permanent damage to their nervous system.
Vaccination is the most effective way to prevent distemper.
Proper hygiene, regular veterinary check-ups, and tick and flea control are also essential preventive measures.


Rabies is a highly contagious and deadly viral disease that affects dogs. It is transmitted through the bite of infected animals, such as raccoons, bats, and foxes. Rabies has serious consequences, including paralysis, aggression, and ultimately death.

How can I prevent canine parvovirus?

The best way to prevent canine parvovirus is through vaccination. Regular preventive care and maintaining the dog's body fluids and electrolytes are also important in treating this highly contagious disease.

How is heartworm spread?

Heartworm is spread through mosquito bites. When an infected mosquito bites a dog, it transmits heartworm larvae which grow into adult worms in the heart, blood vessels, and lungs. Regular heartworm medication and melarsomine injections can prevent this parasitical disease.

What are the symptoms of rabies in dogs?

Rabies is a viral disease that causes inflammation of the brain. Dogs infected with rabies may display symptoms such as fever, hyperactivity, tingling sensation, and burning at the wound. Vaccination is crucial in preventing rabies, as it is a fatal disease that can also be transmitted to humans.

What is canine influenza and is there a vaccine for it?

Canine influenza (canine flu or dog flu) is a relatively new disease caused by the canine influenza virus. It spreads through respiratory secretions and contaminated objects. Dogs can shed the virus before showing signs of illness, making it difficult to detect. While a vaccine for canine influenza is available, it is not recommended for every dog. Vaccination decisions should be made in consultation with a veterinarian considering the specific risks for the dog.
