Large black mole on dog.

Species: Dog
Breed: Labrador
Age: 2-5 years
Hi Dr. Marie, I’m kind of worried because my dog, a Labrador retriever he has had a mole on his belly since he was born, but a few months ago that mole has gotten really big and he is 4 yrs now. The mole that once was really small is now a wart and looks like one of those fat ticks, but obviously is not a tick. I really don’t know much about that stuff and it worries me that it could be cancer; and this dog even thou is Labrador and is suppose to be friendly, he hates everybody except me, so its really hard to take him to the vet, unless is for his yearly visits for the vaccines.

So thank you very much in advance, Zeus and I are really grateful and will be wating for your answer. Have a nice day!

Hi there and thanks for your question. The good news is that most of the time when we see a black wart-like growth it is not anything to worry about.

However, whenever I see a lump that has been present for years suddenly start to change I always want to make sure it is nothing serious.

Unfortunately the only way to know this is to have your vet do a fine needle aspirate. Most dogs tolerate this relatively well.

You may want to ask your vet if they could prescribe a sedative such as acepromazine (atravet) to help Zeus behave better for his visit.

Many black smooth growths on the skin of dogs are benign melanomas. However, again, if one starts to grow then I recommend getting it checked out and possibly removed.
