Her name is Shalina, and she is around 7 years old
She is not pregnant and she never has been.
She has grown these big things where her back boobs are, and she regularly licks them.
They are not "balls" because she is a girl.
They look really abnormal and I need to help her!

I love her so much!

Here are the photos!

Those are either tumors or the worst case of mastitis I've ever seen. Get her to the vet Monday.

Why have you not taken this poor dog to the vet? That growth is huge!

We can't diagnose her. Even if we could, what then? She'll most likely need surgery and treatment, none of which we can offer you.

To the vet, right away, no more putting this off, your dogs life depends on it.

Wow... just wow. Even if that wasn't life threatening (which it very well could be) that would be VERY uncomfortable.

I feel so bad for this poor dog, to have to live with that growth. You're right Shazzy, it can't be comfortable.

She's obviously licking it a lot because it bothers her.

Poor baby. She really needs a vet.

If I had to guess, it looks like your dog may have a large mamary carcinoma. This is why you spay your dogs..
Get her to the vet, please.
