Cephalexin is an antibiotic. It works to eliminate bacteria in the same way as penicillin, in addition to providing some other qualities. Cephalexin also ensures bacteria won't develop a barrier of cells that otherwise would prevent the drug from working. Although the drug isn't approved by the Food and Drug Administration (FDA) for use in animals, it can be prescribed by a veterinarian to treat bacterial infections.

Uses
-
Veterinarians prescribe Cephalexin to cure a number of bacterial infections. Petplace.com states that its uses include skin, bone, and wound infections as well as pneumonia and bladder infections. It's not effective in treating parasitic or fungal infections and viruses.
Other Forms of the Drug
-
A comparable substitute for Cephalexin is Cefadroxil--a veterinary-approved drug. The human form of Cephalexin is called Keflex or Dista and can go by other generic names.
General Dosing Instructions
-
Like most antibiotics, the entire medication should be completed even when a dog shows signs of improvement. This is to prevent a dog's body from becoming resistant to the drug. Depending on the diagnosis requiring Cephalexin therapy, the dog may take the drug orally two or three times a day. The length of time the dog needs to take the drug also depends on the extent of the infection.
Side Effects
-
Side effects are generally rare but are possible in some dogs. Vomiting soon after Cephalexin is given to the dog is a sign of drug sensitivity. According to vetinfo.com, queasiness is preventable when the drug is taken with food and water. Diarrhea, although infrequent, is also possible.
Warning
-
A dog with an allergy to penicillin and other similar types of antibiotics should not use Cephalexin as it can also cause an allergic reaction. A rash, hives, breathing problems, and swelling of the face and mouth are all signs the dog is allergic to the drug; if you notice these symptoms, you should contact your veterinarian for guidance.
