My dog tried to jump on the couch the other day (shes a pomeranian/bichon frise so she is a small dog) and it seemed like she hurt herself cause she yelped in pain. She has broken a toe nail a few weeks and shes been limping for a day or two. But it seems like her limping goes on and off because she will be normal one second and when someone gets home she starts limping again. What should I do? Shes been limping since Monday but its been on and off and I’m not sure.
