Lymphoma is one of the most common types of cancers in dogs. It’s a cancer of the lymphatic system and lymph nodes. Lymphoma can affect many different organs in a dog’s body.

It’s most often found in the peripheral lymph nodes. These are located deep inside of the innermost layer of the skin, also known as subcutaneous tissue.

This kind of cancer can affect all breeds and ages of dogs. However, it’s most often discovered in golden retrievers and dogs between six and nine years old.

Breast Cancer in Dogs

Just like with people, this kind of cancer involves tumors in the mammary glands. Dogs have ten mammary glands that run from the abdominal wall to the chest.

Tumors can show up in these glands. However, they’re usually found in the glands that are closer to the hind legs.

Older female dogs are at more risk of developing breast cancer. Especially dogs that have not been spayed or were spayed after two years of age. English settlers, English spaniels, terriers, and poodles are at higher risk of developing breast cancer.

Bladder Cancer in Dogs

There are several different kinds of tumors that can lead to bladder cancer in dogs. The most common is transitional cell carcinoma. This develops in the deeper layers of the bladder.

As the tumor gets bigger, it might invade the urethra and disrupt the flow of uring, making it difficult for your dog to urinate. This can lead to a serious emergency that requires immediate medical attention.

Bladder cancer is most common in older female dogs and can occur in any breed. However, the most commonly affected breeds include beagles, West Highland terriers, wirehair fox terriers, Scottish terriers, and Shetland sheepdogs.
