Can Cats Get Sick From Dogs? 5 Illnesses & Prevention Tips

If you have both a dog and a cat in your household, you might wonder: can cats get sick from dogs? The good news is that most diseases are species-specific, meaning cats and dogs don’t share many illnesses. However, certain infections, parasites, and viruses can pass between them, posing risks to your pets’ health. This article breaks down the key ailments cats can catch from dogs, their symptoms, transmission methods, and proven prevention strategies. Drawing from veterinary expertise, we’ll help you keep your furry friends safe and healthy in a multi-pet home.

Understanding these risks is crucial for responsible pet ownership. While the likelihood of transmission is low with proper care, vigilance through vaccinations, parasite control, and hygiene can prevent most issues. Let’s dive into the specifics.

Quick Answer: Yes, But Risks Are Manageable

Cats can get sick from dogs through shared parasites, certain bacteria, fungi, and viruses like rabies. Common culprits include intestinal parasites (roundworms, hookworms), ringworm, Bordetella, and rabies. Fortunately, routine veterinary care minimizes these dangers significantly. Species-specific diseases like canine parvovirus or feline leukemia won’t cross over, but zoonotic threats that affect both pets (and sometimes humans) require attention.

1. Rabies: The Most Serious Threat

Rabies is a fatal viral disease that can definitely pass from dogs to cats via bites or scratches. Dogs often contract it from wildlife like raccoons, foxes, or bats, then transmit it through saliva. Once symptoms appear—such as aggression, foaming at the mouth, paralysis, or excessive drooling—rabies is almost always deadly without immediate post-exposure treatment.

Cats are highly susceptible because they hunt and interact closely with dogs. In multi-pet homes, a single bite during play can spread the virus rapidly. Human transmission is also possible, making rabies a public health concern. The CDC emphasizes that while rare in vaccinated pets, unvaccinated animals pose significant risks.

Symptoms in Cats

• Behavioral changes: Sudden aggression or withdrawal
• Neurological signs: Difficulty swallowing, seizures, hydrophobia
• Progressive paralysis leading to coma and death

Prevention

Vaccination is the gold standard. All dogs and cats should receive rabies shots starting at 12-16 weeks, with boosters every 1-3 years depending on local laws and vaccine type. Keep pets indoors or leashed to avoid wildlife exposure. If a bite occurs, isolate the animals and seek immediate veterinary care for quarantine and testing.

2. Intestinal Parasites

Intestinal parasites like roundworms and hookworms are zoonotic and easily shared between dogs and cats. Dogs shed eggs in feces, contaminating shared spaces, litter boxes, or yards. Cats ingest them by grooming, eating infected prey, or accidentally consuming contaminated soil or feces. These parasites can cause diarrhea, vomiting, weight loss, and anemia in cats, especially kittens.

Hookworms attach to the intestinal wall, leading to blood loss, while roundworms create blockages. In severe cases, they migrate to organs, causing pot-bellied appearances or coughing. Humans, particularly children, risk infection from contaminated soil (toxocariasis).

Symptoms in Cats

• Diarrhea, often bloody
• Weight loss despite good appetite
• Lethargy, poor coat condition
• Visible worms in vomit or feces

Prevention

Monthly broad-spectrum preventives like Revolution Plus protect against both fleas (intermediate hosts) and worms. Regular fecal exams at vet visits detect infections early. Scoop litter boxes daily, dispose of dog waste promptly, and deworm new pets before introduction.

3. Ringworm: A Contagious Fungal Infection

Ringworm, caused by Microsporum canis, is a fungus—not a worm—that spreads via spores in hair, skin flakes, or the environment. Dogs with patchy bald spots or scaly skin can infect cats through direct contact or shared bedding. It’s highly contagious, itchy, and zoonotic, causing circular red lesions in humans.

Cats often show minimal signs but shed spores profusely, perpetuating outbreaks. Spores survive months in the environment, making cleaning essential.

Symptoms in Cats

• Circular areas of hair loss and scaling
• Red, inflamed skin
• Broken hairs or brittle coat
• Mild itching or none

Treatment & Prevention

Oral antifungals (e.g., itraconazole) plus medicated shampoos for 4-6 weeks. Vacuum and disinfect environments thoroughly. Prevent by isolating sick pets and using flea control, as it reduces mite/fungal spread.

4. Bordetella (Kennel Cough)

Bordetella bronchiseptica causes respiratory infections transmissible from dogs to cats via airborne droplets or nasal discharge. Dogs spread it in kennels; cats catch it from sneezing or sharing spaces. Symptoms include coughing, sneezing, and nasal discharge, rarely progressing to pneumonia in young or stressed cats.

It’s more common in multi-pet homes or shelters. Humans can rarely contract it.

Prevention

Vaccinate dogs against Bordetella. For cats in high-risk homes, discuss intranasal vaccines. Quarantine sick pets and improve ventilation.

5. Other Potential Risks: Mange, Giardia & Bacteria

• Mange: Certain mites (e.g., Notoedres) pass from dogs to cats, causing intense itching and hair loss.
• Giardia: Protozoan parasite from contaminated water/feces, leading to watery diarrhea.
• Bacteria (Campylobacter, Salmonella): Shared via feces, causing gastroenteritis.

Capnocytophaga from dog saliva can infect via bites but is rare in healthy cats.

Prevention Strategies for Multi-Pet Homes

To safeguard your cats from dogs:

• Annual vet checkups with fecal, blood tests, and vaccines.
• Parasite preventives year-round.
• Separate litter boxes and feeding areas.
• Supervise interactions; spay/neuter to reduce aggression.
• Clean shared spaces daily.

Frequently Asked Questions (FAQs)

Q: Can Cats Get Parvo From Dogs?

A: No, canine parvovirus is species-specific and not contagious to cats. Cats have their own parvovirus (feline panleukopenia), but it doesn’t cross to dogs.

Q: How Do Cats Catch Bordetella?

A: Through respiratory secretions like sneezes from infected dogs or cats. Rare human transmission possible.

Q: Can Cats Get Mange From Dogs?

A: Yes, certain mites like those causing notoedric mange can transfer, though most are species-specific.

Q: Are Intestinal Parasites Zoonotic?

A: Yes, roundworms and hookworms can infect humans, especially children, via contaminated soil.

Q: Is Rabies Common in Vaccinated Pets?

A: Extremely rare due to widespread vaccination programs.

By staying proactive, your dogs and cats can coexist safely. Consult your vet for personalized advice tailored to your pets’ lifestyles.
