My dog Buddy has a big tumor in his ear. Is this cancer? He is 10, how much longer will he live?

最佳回答：

There is a possibility that it is cancerous, but there is no way to know how long he will live. That depends on how fast it spreads, how his general heath is, etc. If he hasn't been seen by the vet for this, you need to take him for an accurate diagnosis and treatment.
