What would cause non painfull swelling at the base of a dog's tail?

Answer 1

If the tail is drooping as well, it can be something called "cold tail." It can be caused by swimming in cold water, though it is not generally understood why it happens. One of my dogs used to get this condition frequently. Its not really problematic, and usually goes away within a day. If it continues, you should probably see a vet.

Answer 2

This could be a cycst, burn, wart, ingrowing hair, scar tissue, or a cancerous or noncancerous tumur among other things. If you have only noticed it recently then it is not a reason to panic, but it would be wise to have it checked soon by a vet.

Answer 3

I thought my dog's swollen tail was due to anal gland problems. He did need them expressed but my vet told me that dogs store fat in the base of their tail, and that it's normal. An over weight dog will have much more. (my dog was 4lbs over weight)

However, if you dog has other symptoms related to his anal area, I would suggest calling your vet.

I hope this is helpful.
