I live in Punta Cana and have a 1year old rescue dog. I recently left town for a few weeks and she stayed at the vet for the first weekend, then was picked up by some friends that have watched her before. They said that she is no longer the same dog and has come back very aggressive. They also said that she has snapped at a few people, has been pacing around and is aggressive. Has anyone heard of this happening before? I'm very worried because I am not in the country right now. Can anyone suggest someone that could help with this. I really do not want to have an aggressive dog because I have her around children regularly, and she has always been so sweet and gentle before....any advice would be appreciated!!!
