Hello. Maybe someone out there can help me. I have a 5 year old yellow male lab. Starting yesterday he started having his normally wagging tail tucked way in and down, no wagging. He still ate yesterday and had his appetite. Just the day before he went on his regular walk and felt great. This morning he did not eat his breakfast. I felt around his body and when I get to his tail he actually yelped! So something to do with his tail, but do not see anything or any redness. Any ideas? You can also tell from his face he's not feeling well. Also has a real hard time sitting.
