JA: I'm sorry to hear that. Some lumps are serious and some aren't. Let's see what the Veterinarian has to say. What is the dog's name?

How big is that lump?

Is it smooth, or sort of bumpy?

Is it squishy, or hard to the touch?

Customer: replied 1 month ago.
About an inch to two in circumference hard to the touch smooth

Great. Thanks for the additional information. I really appreciate it.

The lump is something that could have many causes: inflamed lymph node, sebaceous cyst, lipoma. Because of her age and the description you gave me of what it feels like, I'm suspecting it's a lipoma or a sebaceous cyst, but I'm just guessing.

Here's more reading on lipomas and other cancers: http://www.thepetcenter.com/exa/lumps.html

The only way to positively identify what sort of lump or bump your dog has is, unfortunately, also through a trip to the vet. A fine needle biopsy (where the vet inserts a needle into one of the bumps and tries to aspirate/pull out material to look at under the microscope) will tell the vet, without question, what sort of problem your dog is having.

I hope this helps.
