Dogs can catch worms from cats, and it's not just a matter of them being in the same household. The most common type of worm that can be transmitted from cats to dogs is Toxocara cati, a type of roundworm.
This type of worm can be present in cat feces, which can then be ingested by dogs through contaminated soil, food, or even by licking their owner's face after playing with a cat that has worms.
In fact, dogs are more likely to get worms from cats if they spend a lot of time together, especially if they share food or water bowls.

What Are Intestinal Parasites?
Intestinal parasites are tiny organisms that live inside your dog's intestines and feed on their nutrients. They can cause a range of health problems, from mild digestive issues to severe weight loss and even organ failure.
Some common types of intestinal parasites include hookworms, roundworms, and tapeworms. Hookworms can cause anemia and weight loss in dogs.
Intestinal parasites can be transmitted through contaminated feces, soil, or water. Dogs can also catch them from fleas, ticks, and other insects that have come into contact with infected feces.
Dogs with weakened immune systems, such as puppies or seniors, are more susceptible to intestinal parasite infections.

Symptoms and Signs Your Pet May Have
If your pet has intestinal parasites, you may notice a dull coat, which can be a sign of underlying health issues. Diarrhea is also a common symptom, and it's essential to keep an eye out for this in your pet.
Puppies and kittens are especially at risk for health complications from intestinal parasites, and in serious cases, these parasites can be fatal. This is why it's crucial to monitor their health closely.
You may be able to see worms in your pet's stool, bedding, or under their tail, which can be a clear indication of a parasite infestation. This is more common in puppies and kittens.
Some parasitic infections can be transmitted to humans, causing serious health issues in adults and children, including scarring inflammation. This is known as a "zoonotic" infection.
Here are some signs your pet may have roundworms:
- Stunted growth in puppies and kittens
- Bloated and/or painful abdomen
- Diarrhea
- Worms present in vomit or stool
- Sometimes pets display no signs
It's worth noting that some pets may not display any signs of having intestinal parasites, making regular check-ups with your veterinarian crucial to detect any potential issues early on.
Diagnosis and Treatment
Diagnosis of intestinal worms in dogs and cats often starts with a stool sample test. This test can detect microscopic eggs laid by adult worms.
A routine stool sample test may not always be enough to diagnose a parasite, especially for single-celled parasites like giardia, which requires a special solution to be added to the sample.
Detecting tapeworm eggs can sometimes cause false negatives, and if the intestinal worms are not mature enough to be producing eggs, the fecal sample test will give negative results.
Multiple fecal tests over a period of time may be needed to successfully diagnose infection by an intestinal parasite.
Once a diagnosis is made, intestinal worms can be treated using a dewormer solution. Veterinarians have the most powerful and effective dewormers available for treating your pet.
Some medications are effective in treating infections, and typically, multiple doses are necessary to fully eliminate roundworms.
Giardia
Giardia is a single-celled intestinal parasite that can infect dogs, cats, and humans.
Infection occurs through contact with contaminated food, water, soil, or fur. Diarrhea is a common symptom, but unlike some other parasites, there's usually no blood in the stool.
Diagnosing giardia can be tricky because it often has no symptoms. Multiple stool samples are needed to confirm the infection due to the specialized tests required.
Diagnosis
Diagnosis of intestinal parasites in pets involves a stool sample test to detect microscopic eggs laid by adult worms. A veterinarian will mix the sample with a solution that makes the eggs more visible underneath the microscope.
In some cases, a routine stool sample test may not be enough to diagnose a parasite, especially if the intestinal worms are not mature enough to be producing eggs. This is why multiple fecal tests over a period of time may be needed to successfully diagnose infection by an intestinal parasite.
Detecting the single-celled parasite giardia requires a special solution to be added to the sample. This is an important detail to keep in mind if your pet is suspected of having this type of parasite.
A definitive diagnosis of roundworms in dogs and cats can be made by the presence of roundworm eggs on microscopic exam of stool, also known as fecal analysis.
Preventing Intestinal Parasites
Preventing Intestinal Parasites is crucial to keep your furry friends healthy. Good sanitation practices are key to preventing infection by intestinal parasites.
Clean up your pet's droppings as quickly as possible to prevent the spread of infection. This is especially important for dog owners, as their pets can pick up parasites from contaminated soil or water.
Preventing your pet from eating soil or grass is also essential, as these can contain parasitic eggs. I've seen dogs dig up the yard and eat the dirt, which can be a nightmare for pet owners.
Using a monthly heartworm preventative medicine for your pet is a must, as it can help prevent parasite transmission. Flea prevention treatment is also crucial to prevent parasite transmission to your pets from infected fleas.
To protect against tapeworms, fastidious flea control is a must for all pets in the home. This means using flea prevention treatment regularly and keeping your home and yard free of fleas.

Here are some essential steps to prevent intestinal parasites in your dog:
- Clean up your pet's stool from the environment as soon as possible.
- Use a monthly heartworm preventative.
- Prevent pets from hunting.
Remember, it takes about four weeks before roundworm embryos can cause infection, so it's essential to act quickly if you suspect your pet has ingested contaminated soil or water.
How Dogs Get Worms
Dogs can get worms through contact with infective worm parasite eggs in the environment. This is the most common way they become infected.
Roundworms, in particular, infect dogs and cats through contact with fecal matter, where the roundworms hatch their larvae. Pets can become infected by roundworms through ingestion of infected soil, licking fur and paws that have come into contact with a contaminated source, drinking contaminated water or coming into contact with cockroaches that carry roundworm eggs.
Dogs can also get tapeworms by swallowing infected fleas, while hunting or scavenging, or when eating uncooked meat or innards of a dead animal.

How Dogs Get Worms
Dogs can get worms through contact with infective worm parasite eggs in the environment.
Dogs are most likely to get worms by ingesting contaminated soil, fecal matter, or contaminated water. They can also get worms by licking fur and paws that have come into contact with a contaminated source.
Roundworms are the most common type of intestinal parasite and can infect dogs and cats through contact with fecal matter. Roundworms can also infect humans through ingestion or skin contact.
Dogs can get tapeworms by swallowing infected fleas, while hunting or scavenging, or when eating uncooked meat or innards of a dead animal. Tapeworms require an intermediate host, a flea, to complete their life cycle.
Dogs can also get worms by coming into contact with wild animals that may carry parasite eggs. This is especially true for pregnant dogs and puppies, who should be thoroughly dewormed at appropriate intervals to prevent infection.

Hookworms
Hookworms are a common intestinal parasite found in dogs and cats, but most commonly in dogs. They are found in the intestines of a dog and suck blood from their walls.

Hookworms can infect dogs through various means, including ingesting soil or water with the larvae in it, when larvae penetrate through their skin, or when they eat an infected rodent, bird, or animal. This can happen when your dog is playing or exploring outdoors.
Young dogs, including puppies, are more susceptible to hookworms and can show symptoms such as lethargy, diarrhea, anemia, and even death if left untreated. Adult dogs may not show symptoms, but they can still be infected.
Hookworms can be transmitted to humans through accidental consumption, such as petting a flea-infested dog or cat, or by walking barefoot on contaminated areas. This can cause a mild to severe itchy rash and visible track marks on the skin.
Hookworms can lead to serious intestinal infections, respiratory problems, gastrointestinal issues, and even anemia due to blood loss. To avoid the risk of hookworm infection, it's essential to treat your pet against worms and take precautions when walking outdoors.
