What is on ky dog's butt?

[narwhalslife]

My dog has had this bubble on her but for almost 2 years now. I thought it was a tumor, It still can be. here is a picture imgur.com/a/5niUD l Every time i look up anal gland on a dog they all look different so i dont think its that, plus i tried to express her anal gland and i wanst able to.

I coul not connect to your picture. I highlighted then right-clicked, (firefox) and that should have led me to your pic's URL but it didn't. So I'm sorry but I can't see what this lump is like.
Anyway, it would be impossible for me or anyone else here to diagnose this. Only a vet can do that.
I tink the best thing is to suggest to the person who is responsible for her going to the vet, that they should get the lump checked out. Sometimes they can tell easily what it is (if it is a fluid filled cyst for example) -and sometimes they need to do a quick needle aspiration. If so, that is done in a few minutes, and rarely means the dog needs sedation.

I am not the one who takes her to the vet. but shes been there many times. It started out as the size of an acorn then  about a year lader it was the size of a golf ball.

PLEASE DO NOT try to express a bubble,lump,tumor
not only would this be very painful for your pup,it may
not be the best way to go.
TWO YEARS the dog has had this "bubble" what did
your vet say about this,what did the vet say it was
when this was checked?
Please come back, let us know what this was.
