Pet's info: Dog | Labrador Retriever | Male | neutered | 8 years and 6 months old | 70 lbs
I have an 8 year old, male lab. In the past two weeks I have notice a rather large, soft bubble, in his upper breast bone, sternum, neck, It fits in my hand. Today I have noticed he is sore/sensitive in his neck, close to his ear. He is active, eats well, and for the most part, is healthy. Is this something I should be concerned about, and can you give me an idea as to what it could be?

Hello, sorry to hear about Pounder. It sounds as though that lump may be a fatty tumor especially if it is not painful, firm, or hot to the touch. Other causes may include a malignant tumor which may need to be further assessed. The best way to obtain a diagnosis on benign vs a malignant mass is to get a needle aspirate of it and look at the cells under a microscope. Sometimes, a biopsy may also be necessary to obtain a diagnosis. The mass may be associated with his ear sensitivity, although, him being a lab, I would be suspicious of a separate issue with his ear such as an ear infection. Since Pounder is otherwise eating and drinking ok, I would recommend scheduling an appointment with your veterinarian at your best convenience to have his mass and ears looked at. Unfortunately, Labs are notorious for getting cancer and I would not recommend just monitoring this mass. Best of luck and hope this helps!
