Lump Near My dogs Penis.

[DudeMcDuddyDude]

Hello.

I have a 1-2yr old pomchi. He has had a lump near his penis, since he was a baby. My ignorant self thought it was because of the umbilical cord. But recently it has grown a little. And it appears to have a white spot on it. It also appears to be attached, it doesn't move when touched. It is also very solid and about finger nail size. But it doesn't cause him any pain or irritation, as if it wasn't even there.

My advice is take your dog to a good vet and get the little lump checked out. The vet may do a "needle biopsy" (or "fine needle aspiration") on it to check what kind of cells are in there. A needle biopsy is never 100% definite a diagnosis, but is pretty clear when it comes to telling if thiose cells are just fatty cells or whatever.
It only takes a few minutes to do, and doesn't require sedation or anesthetic. But you will need to hold him nice and still while the vet gets the needle into the lump. He won't much like it, but it is quickly done. Some vets can tell you within a few minutes what the results are, and it doesn't always have to be sent to a lab.
