I have a 6mo old female lab and about three days ago I noticed that she had a slight limp on our walk. It didn't seem to bother her and it she only limped during the walk. Yesterday on our walk, she was limping again and today she limped more, and more pronounced.
Now, the thing is that she only limps on our walk on asphalt. If she's on grass, she's fine. We go outside and play fetch and she runs until she's tired. Inside the house, on carpet, tile, and hardwood floors she's fine. She didn't want to stop walking today but I stopped because I wanted to make sure that she wasn't really hurt. But we went out to the yard and ran around right away. I can touch her pads, her legs and move her limbs without any issue.
I don't cut her nails because we walk daily which keeps them short enough. Are they maybe too short from walking and the nails are bothering her? The webbing inside her pads looks pink all over and there are a couple of places that it's a bit redder.
I'm not sure if I should be worried since she is fine everywhere else except asphalt? I know this sounds crazy...but any help would be great!
