My bitch is a senior dog about 8-9 yrs old, and extremely overweight. She made very loud snoring / breathing when she is resting / sleeping. It is common for dogs to snore, but I suspect her heavy breathing is due to the obesity. Will it pose any serious health condition? She has annual health checkup and all clear at the moment.
Another issue, her hind leg was replace with artifical bone due to fracture in her younger days. Its getting weaker everyday, despite having 1000mg of glucosamine. Walking is a strain for her, what can I do to improve?
