I've also posted this in 'doghouse' but haven't yet had a response.
Yesterday morning, I saw that my dog had a massive bulge in his neck. We have been to the vets and they said it could be an abscess. They tried to drain some fluid but couldn't. They were able to take a little sample to send off to be tested. He's on antibiotics.
I can't tell you how worried I am. Every time I look at him I get upset. I'm hoping it's nothing serious. It looks bigger today but the vet said it could be swelling from inserting a needle yesterday.
They also said it might go down in around 3 days due to being on antibiotics.
Have you had this experience and how was it?
