I was cutting weege (7yo) nails and cut one if the back ones too short, I sorted it and she was fine. I got help doing her front ones because she's wriggly and they were all fine. I put her back on the floor and she's holding her front right paw under herself while she walks and keep just laying down and occasionally having the smallest teeth grind. We weren't rough but we were quick with any positions that might hurt for a while. Writing this she's cleaning herself with the paw fine but still won't walk on it. I've given it a feel over and nothing seems to be wrong. Could it just be like a pulled muscle or sore?
