How to Keep Your Dog From Making Your Cat Sick and Vice Versa

Cats and dogs are susceptible to diseases, parasites, and infections from a variety of sources, like wild animals, fleas, and other animals of their own species. However, you might be surprised to know that dogs and cats can transfer some illnesses between their species, so it’s important to make sure to protect both of your pets from each other. This guide will explain what diseases you may not have known can spread between both cats and dogs, and what you can do to protect them.


Haemobartonellosis is a form of parasitic blood infection that can hurt cats and dogs. This disease is caused by a form of fungi, which can be spread by fleas or ticks. The disease can be fatal, if left untreated, and may cause severe anemia, a lack of appetite, and fever in animals. Once a cat or dog is infected, they are unlikely to be able to beat the illness on their own and need medical treatment, which usually includes antibiotics and blood transfusions.

Unfortunately, this disease is easily transmitted by bites from pests, which will gladly jump from your cat to your dog, and vice versa. If you don’t use a flea or tick repellent, or use a brand that fleas have mutated to resist, all it takes is one bite to spread this disease between your two pets. Even if your cat doesn’t go outside, a quick walk outdoors with your dog could potentially infect it, and bring home the pest to spread the disease to your cat, as well. Talk to your veterinarian about choosing a prescription anti-flea and tick medication that is effective for both your pets. Make sure to prevent your cat and dog from fighting, as well, since the disease can potentially be transferred from an infected pet to a healthy pet via bodily fluids and bites.

Kennel Cough

If you have a dog, you’ve probably heard of kennel cough; this upper respiratory viral infection can spread rapidly through dog kennels, hence the name. However, cats are susceptible to the illness, too.

Kennel cough is caused by bordetella, a form of bacteria. A bordetella infection causes the same symptoms in cats and dogs: lethargy, fever, sneezing, and coughing. If you notice one of your pets having these symptoms, you should keep them away from your other pet(s) and take them to a veterinarian immediately.

Thankfully, there’s a vaccination that can protect cats and dogs from bordetella. Having all of your pets vaccinated against this bacteria will help them to live happier and healthier lives together.

Cats and dogs may not have much in common, but they do share certain illnesses and parasites. Talk to your vet about taking preventative measures to keep your dog and cat safe from getting each other sick. If you’re looking for more specialized help, consider looking into clinics that focus on a certain pet, such as Cat Care Clinic.
