My old Cocker (12) Topaz, as suddenly stopped wagging her tail, it just hangs straight down, she has had no damage to it and she doesnt move fast enough to have done any area strain, she suffers greatly with the heat, so moves relatively slowly . All the info I have on the condition implies it is common in young males who exercise a lot???......she is eating ok, but she alwas wags her tail albeit slowly , seems odd to have it just hung there, she doesnt seem to feel any pain etc in the area, has anyone come across this in their dog or has any ideas what it could be?
