Cephalexin for Dogs Works like Penicillin

- Hives
- Rash
- Shortness of breath
- Swelling of the face and mouth
If your dog shows any of these symptoms after taking cephalexin, contact your veterinarian immediately.

If your pet is showing these side effects of the medication and it's possible you might have given too much medication, contact your veterinarian.
