What Are The Symptoms Of Hookworms In Dogs?

Hookworms in dogs are tiny parasitic worms that can live inside a dog’s intestines. They survive by feeding on the dog’s blood supply and can increase in numbers very quickly. If your dog gets hookworms, there’s no need to panic as they usually only cause mild symptoms in adult animals. However, they can cause discomfort and health problems for your dog in the long term. For this reason, it’s important to recognize the signs of hookworms and know what to do if your dog develops symptoms.

How Do Dogs Get Hookworms?

Dogs usually get hookworms by accidentally ingesting hookworm larvae, usually by eating the feces of an infected animal or contaminated soil. Water can also become contaminated with hookworms, infecting animals that drink it. Hookworm larvae can burrow into a dog’s skin if they lie or walk on contaminated soil. This is most likely to happen on the pads of their paws. The larvae could then get into the dog’s digestive system when they groom themselves.

How Are Hookworms Diagnosed?

If you notice symptoms of hookworms in your dog or puppy, you should take them to the vet as soon as possible. The vet will carry out a diagnostic test for hookworms known as fecal float. This involves examining a sample of the dog’s feces to check for hookworm eggs. The test is very reliable at detecting hookworm in adult dogs as hookworms lay large numbers of eggs each day. However, the test may not easily detect hookworms in puppies until they are severely infected because it takes several weeks for the larvae to mature in their intestine.

Hookworm Life Cycle

Hookworms have a 3-stage life cycle, beginning with eggs which pass into an infected animal’s feces. The eggs hatch into larvae which can survive in the environment for months. When a dog becomes infected with hookworm larvae, they pass through their digestive system into their intestine where they grow into adults. These adult hookworms lay eggs and the life cycle begins again.
