re: My dog has a huge abcess thingy on her neck under the skin

Well glad the dog is ok. If it was a snake bite the swelling should subside by the weekend. If not your vet may have been wrong. Don't get caught up in how long they have practiced and where they went to school. I have seen Cornell bet grads incorrectly diagnose shite and older vets tend to think they have seen it all and refuse to stray from the norm because its outside their comfort zone. Has you dog ever been bitten before?
