5 Signs That Your Dog Has Worms

There are many different types of worms your dog can get, from heartworms to hookworms. These worms can cause your dog to become ill and some even lead to more serious problems. Here are some common signs that your dog has one or more types of worms.


One of the first things you might notice with your dog is that it has become lethargic. The signs of lethargy are sometimes subtle in the beginning, starting with simply not wanting to go on as long of walks as they used to, to possibly playing less while indoors. Pay close attention to the overall energy level of your dog, since diminishing energy could be a sign of worms or other medical issues.

Stool Changes

Changes in your dog’s stool is another common sign of worms. First of all, the stool may become softer or watery if they have certain types of worms, such as hookworms. Hookworms can also cause blood in the stool. You might also notice simply soft stools, a change in their color; or, you might actually see small worms moving in the stool. Another thing to look for in the stool is small white bits, which are common for different types of worms.

Appetite Changes

If your dog has had changes in their appetite or eating habits, it is always a cause for concern. While this could be nothing, it could also be a warning sign of worms or other medical issues. Take notice of when your dog eats less than normal, eats slower, or seems to be uncomfortable when eating their meals. Talk with a vet, like Gulfport Veterinarian, right away if you notice any extreme changes. Worms have a tendency to cause discomfort in the abdomen, which could your dog to lose its appetite. On the other hand, some worms take your dog’s nutrients, so your dog may be hungry all the time.


Many types of worms can cause coughing in your dog, including hookworms, heartworms, and roundworms. Since coughing tends to occur when the worms have been in your dog’s body for a while, it is best to get them checked out. It is very possible that the coughing is for another reason, but it still warrants a visit.


Lastly, your dog might be suffering from worms if it has been vomiting. Roundworms are the biggest reason for vomiting, though any type of worm can upset your dog’s tummy and cause them to vomit their food. Look at the vomit to see if you notice worms–though they won’t always be noticeable. However, roundworms do tend to make themselves known in vomit.
