Nobody wants to think about the “C-word,” but unfortunately, cancer is a leading cause of death among dogs. According to veterinary oncologist Dave Ruslander, 50% of dogs over age 10 will develop a type of cancer.
As the body ages, its disease-fighting immune system weakens, and it becomes more vulnerable to disease. It’s important, therefore, to learn the early signs of cancer and the different types of canine cancer to keep your dog as healthy as possible for as long as possible—in addition to providing a wholesome diet, age-appropriate exercise, and mental stimulation.
There are many symptoms that point to the possibility of dog cancer. Each one of these symptoms can be caused by another condition. However, if you notice your dog having a few of these warning signs at the same time, it’s best you bring your dog to a vet for a check-up.
Collapsing is a major warning sign for dogs. This is because dogs are usually active and playful when they are awake. If a dog is always napping or sleeping instead of greeting you when you are near, it is a sign that there is something is out of the ordinary happening. Pay attention to the baseline of activity of your dog so that you will automatically notice when it is collapsing from lethargy.
And don’t wait out to see if your dog is fine after some time. The symptoms of collapsing, lethargy, and weakness are usual signs of dog cancer. Bring it to a vet for attention as quick as you can. This is particularly true in the large breed dogs, like the Great Dane or Saint Bernard breeds. Even though they may collapse and seem fine the next time, it could be a sign that there’s a tumor of the spleen.
