What if my dog has worms and they go untreated?

We can usually see some GI issues—vomiting, diarrhea, inappetence, things like that—that tell you that your dog has an upset stomach. If left untreated, especially in smaller dogs with hookworms, we can see what's called hookworm anemia. And that is something that can end up being fatal, so you always want to make sure that if your dog does have diarrhea or you see worms, you're getting to your vet pretty quickly.

If your dog has worms, their overall health can be significantly affected. They may experience blood loss, become very lethargic, lose weight, and suffer from chronic gastrointestinal issues. It is crucial to seek veterinary help if you suspect your dog has worms.

If left untreated, worms can cause extreme discomfort, weight loss, and bloody diarrhea. In puppies and kittens, they can lead to anemia which can be fatal.

Untreated worms can actually cause a dog to die. This is because it causes so much GI upset that the dog is not getting the proper nutrition.
