Could your dog have worms? It’s almost certain that puppies have worms at some point in their lives, but what about your adult dog? Can adult dogs get worms?
Don’t panic! It’s normal.
Worms are one of the most common health problems dogs have.
They get worms from a number of sources, including the environment. It’s one of the reasons you bring a little bag of fresh poop when you go to the Vet – he/she can monitor for them quickly. Worms can be harmful to your dog — and to you and your family — so here’s what to watch for.
5 Most Common Worms Dogs Get
- heartworms
- roundworms
- hookworms
- tapeworms
- whipworms
As the name says, heartworms are found in the dog’s heart and blood system; the others are found in the intestines.

Symptoms of worms
Dogs don’t always show signs of worms, and may seem to be in good health. That’s why Vets test (via the ‘fresh bag of poop’) and it’s why routine de-worming might be recommended, depending on your Morkie’s lifestyle.
Some worm eggs or larvae can live in your dog and stay dormant. They’re activated only in times of stress, or in the later stages of pregnancy. Then, they grow like mad, infesting the soon-to-be-born puppies and kittens.

Regular Stool Tests at Your Vet's are Very Important
Even dogs who get regular parasite preventive meds, are susceptible to a variety of worms and diseases.
When you take a stool sample to your Vet, he/she uses a flotation test that can identify intestinal parasites and Giardia, a parasite that causes severe diarrhea.

Scooting isn’t always a symptom of worms
Worms rarely cause that infamous bumwalk – when your Morkie scoots, it’s more likely impacted anal glands or a food allergy.
Only your Vet can confirm the cause.
The 4 most common intestinal worms

Roundworm
Roundworm is a common, worldwide parasite; dogs get infected by sniffing or licking infected feces. They’re also spread by rodents, earthworms, roaches, and birds, Roundworms are very serious for puppies; they can cross over to humans, especially children playing in areas with lots of old dog poop around.

Hookworm
The hookworm attaches to the lining of your dog’s intestinal wall and feeds on the blood. Its eggs are ejected into the digestive tract and pass into the environment through your dog’s feces. They’re a serious threat to dogs because they’re consuming blood. For puppies, the threat is even bigger. Humans CAN be infected with hookworms from dogs.

Tapeworm
Tapeworms are long, flat worms with segmented bodies. They may look like grains of rice. Dogs with tapeworms aren’t always sick. Fleas are an intermediate host for hookworms, so keeping your Morkie flea-free is important. Tapeworms can also be spread by mice and other rodents. People are rarely infected with them.

Whipworm
Dogs with whipworms may have no symptoms at all; however, a serious infection can kill your dog! Dogs with a bad case of whipworms will often have bloody poop. Whipworms can be more difficult to diagnose, so seeing a Vet for regular feces testing, is vital.
