HELP!! I have a 8 week old puppy that was walking and running fine till a few days ago. I had here out walking when her front legs started shaking and it looked like her knuckles where about to... i dont know it just looked weird. Its kind of like she is walking on her tip toes. I have been reading alot on the internet that a high protein diet might cause this. We have a vet appt. later this week but I want to know is there anything I can do to help her. We had here on a high protein diet which I have changed to a low protein (natural balance). Will she get better or will it always look like she is walking on her tiptoes? Please any advice is welcome. Thanks in advance.
