You should take your dog to the vet soon cuz there are lots of things that can cause fluid under the neck. My Alphie had an antibiotic cause this type of thing and vet said it was a side effect. Oh hey it could be yours has an abcessed tooth.
My dog got bumped by a car. We took her to the vet and as a less expensive option, the vet prescribed her with antibiotics and pain medicine. 2 days later this soft lump of fluid appeared on the left side of her neck. Hope it the anitbiotic. Thank you! add a comment
