Signs Of Cancer In Dogs

November is Pet Cancer Awareness Month! Cancer is quite common in our canine buddies. It’s particularly in dogs over age ten. In fact, about half of them will develop cancer. Different types of cancers all have their own warning signs to watch for. Some develop very quickly, while some spread slowly. That said, there are some things for you to keep an eye out for. A Plano, TX vet offers some insight on this below.


We know, Fido certainly loves his snacks. However, while obesity is by no means uncommon among dogs, it isn’t the same as bloat. If your pet’s belly looks swollen and you aren’t sure why, it could be a sign of medical issues, such as cancer.

Unexplained Bleeding

Another red flag—literally—is unexplained bleeding. If Fido is bleeding from his nose, ears, mouth, or nether regions, contact your vet right away.

Respiratory Issues

Fido may pant a bit if it’s really hot, or if he’s just been playing Fetch or Frisbee. However, if he’s panting a lot and you aren’t sure why, or if you notice him coughing, gasping, or wheezing, there may be something going on.

Gastrointestinal Upsets

Any time an animal has difficulty eating and/or digesting their food, it’s a cause for concern. Trouble swallowing, reduced interest in food, vomiting, and diarrhea are all red flags.

Weight Changes

Unexplained weight gain or loss is always a sign that something isn’t right. If your furry pal is gaining or losing, and the changes can’t be explained by adjustments in Fido’s diet or exercise routines, there’s a chance your pooch could have cancer.

Visible Masses/Lumps

Neoplasias, or visible lumps, are extremely common in dogs. In fact, about one in four pups will develop them at some point in their life. The good news is that they aren’t always cancerous. However, these definitely need to be checked out right away.

Uncharacteristic Behavior

It’s important to spend time with Fido every day, and just pay attention to him. Any behavior that seems out of character for your furry friend is worth noting. For instance, if your canine pal has been losing interest in his favorite toys, or is acting unusually withdrawn, sullen, or cranky, reach out to your vet.
