Does My Dog Have Worms

Does My Dog Have Worms

Let’s get real: dog worms are common, and they’re not just a “gross” problem—they can be a family health issue too.

The CDC explains that dogs can shed worm eggs/larvae in feces, contaminating soil and environments—and that roundworms and hookworms can infect people

How dogs get worms (the short version)

Common routes include:

  • Puppies infected before birth or via mother’s milk

  • Swallowing contaminated soil or fecal material

  • Hunting/ingesting prey or scavenging

  • Fleas (for certain tapeworms)

Signs your dog might have worms

Some dogs show no signs. When they do, you may see:

  • Pot-bellied appearance (especially puppies)

  • Diarrhea or vomiting

  • Weight loss despite appetite

  • Dull coat, low energy

  • “Scooting” (not always worms, but worth checking)

If your dog is very young, unwell, or losing weight—call your vet.

Why it matters: zoonotic risk (humans can be affected)

CDC highlights that roundworms/hookworms are zoonotic—meaning they can infect humans. 

The good news: prevention is straightforward.

The “clean + consistent” worm prevention routine

1) Pick up poop fast
The longer feces sits, the more contamination risk builds.

2) Keep kids’ play areas protected
Avoid fecal contamination in yards; cover sandboxes when not in use.

3) Use routine deworming / broad-spectrum parasite control
CAPC general guidance includes routine parasite control as a foundation for pet and public health. 

4) Don’t guess—test when needed
If your dog has ongoing GI signs, a fecal test can help your vet target the right parasites.
