Thats great she is feeling better! If it is arthritis - Sasha's Blend works wonders.
My then 12 year old Staffy wouldn't get up unless he had to and didn't want to play ball that much. He was always sleeping. Within a few days of Sasha's Blend he was bouncing around like a three year old.
He is now 13 and was getting a little bit stiff but now on pain relief medication as well. He is now bouncing around like a two year old. lol.
Hoping it is arthitis and not anything nastier.
