My female corgi is just 7 years old but I have noticed she has really slowed down lately. She doesn't want to walk down steps, and is very stiff upon rising, like her back legs drag before she gets her bearings. She can walk normally after a few steps, will do some running and playing with my other Corgi, but tires quickly and just wants to come back inside. She was overweight a few months ago but we have gotten her weight down to 31-32 lbs. Is it unusual to have a corgi develop hip arthritis this young? I know there are medications to help with pain and inflammation--I was wondering if anyone out there has had experience with them. Please email me. ccuz@bellsouth.net
