Hi all, I have an 8 yr old ober who has knee problems. I knew this when I got her 4 yrs ago. Her knees swell up then go down. Last night she was moving kinda slow and not wanting to get up. Today, she is down, and won't get up on her feet, and she is walking on her knees. I tried helping her up, but it is like her knee joints are froze in a bent position. Should I put her down, or is there something else I can do for her? :Bawling: She is one of my favorites.
