Cancer is one of the most serious and feared illnesses that can affect our four-legged companions.

Especially in dogs over 10 years old, cancer is among the leading causes of death.

But there’s hope—early detection can give your dog a real chance at effective treatment. Read on to learn how to act before it’s too late!

Cancer can strike dogs of any age, not just older pets.

If we want to ensure our loyal companions live long and happy lives, recognizing the early warning signs is crucial.

Pay attention to these symptoms and contact your veterinarian immediately if you notice anything unusual.

While many lumps are harmless, others could be mast cell tumors, a type of cancer commonly seen in dogs.

These tumors can spread quickly to lymph nodes, the liver, or the spleen.

Even a small sore that won’t heal could be a red flag.

Don’t ignore it—your dog’s life could depend on a simple examination.

A strong, foul odor from your dog’s mouth isn’t just unpleasant—it could be a sign of oral cancer.

Your prompt action could make all the difference.

If your dog suddenly starts limping or showing pain in a specific leg, it might be a sign of bone cancer.
