Hello everyone! Our English Mastiff is 9 months old and he has started limping and whimpering when he’s laying down. It’s been about two weeks now, some days are better than others. We took him to the vet and she said maybe he strained something or growing pains. She prescribed Rimadyl but we don’t want to give it to him. We’ve read some concerning things about it. I have ordered some natural supplements that are arriving today. I found some information about Panosteitis online. Does anyone have experience with this happening to your Mastiff? Any help is appreciated. Thank you!
