Lately I've noticed that Buddy is walking a bit funny. He has a sorta waddle, like he's always straddling something when he's walking. I've felt him for lumps and I couldn't find any. I've read about hind leg degeneration, but that seems to be something that occurs in older ratties. Buddy is only a year old. He also seems to be able to jump up on the couch ok and get up/down the ramps in the DCN, so I don't think he's losing power. It just seems to effect the way he walks/runs. Is there anything else that could cause this? Is there anything I can give him to help? He seems a little less active then usual lately too so it's possible whatever this is is causing him some pain. Is there a pain reliever I could give him safely and see if it helps?
