Please see a vet or your mentor breeder. As stated in the rules:
Most people on this forum are against declawing cats, and are against banning specific dog breeds. Most people on this forum are VERY pro spay/neuter, and are against backyard breeding. Most people on this board will beg, borrow and max out their credit cards to see a veterinarian when their pets are ill.
