My dog is a 105-110 pound golden doodle. He has always been about 95 pounds since he was young and skinny so he is not super over weight but recently since we have gotten a second dog he likes to steal her leftovers and has been getting a little chubby. He is also 5 years old. We have noticed he walks a little odd for a while, even before he gained weight and just though it was because he was very big. I recently realized one of the reasons it looks so odd when he walked and especially when he runs. His hock ankles where it almost looks like an elbow on his rear legs almost flexes when he walks. I’m not exactly sure how to describe it but when he runs this point On the back of his leg almost hits the ground with every step. He has been to the vet many times and always been in good health but we are worried about early joint problems. I just want to know if anyone has experienced/noticed this in their dog and is it normal and just part of how he walks or is it a concern? We will definitely ask the vet next time he needs to go for a routine visit but just want to make sure we don’t need to schedule an appointment soon to get this looked at.
