Sasha was diagnosed with pretty severe arthritis in her hips as well as in her spine, a month ago, which explains her dramatic slowing down through July, and August and continuing. Some days the meds kick in (Metacam) and she is happy to go for a reasonably good walk, other times, not so much. So life has changed and instead of the long hikes we were doing in early summer, we now advance slowly down the trails for shorter distances, and she likes to rest often. It is not fair that dogs get old after only 12 years!
