When do we take her to the vet? We've inspected her paws, nails, and legs and everything seems okay. She's still running around and playing, but is favoring her leg and limping. When we touch her leg and poke around it doesn't seem to bother her. Should we let it go overnight and see how she is in the morning? She has seasonal allergies that just started acting up this week so her paws are flakey and itchy, but it's all of her paws and happens every year, so I don't think it's that. I feel so bad for her.
