Common Uses of Cephalexin in Dogs

Cephalexin For Dogs

Cephalexin is often used to treat skin infections, wounds, abscesses, and respiratory tract infections in dogs. It works against susceptible bacteria like Staphylococcus aureus that can cause skin problems and Streptococcus that may lead to respiratory illness.

  • For skin infections, cephalexin clears up conditions like hot spots, infections around the eyes or mouth, and infected wounds or surgical sites. It reduces swelling, redness, and discomfort while fighting the underlying infection.
  • For respiratory infections, cephalexin can treat pneumonia, bronchitis, tonsillitis, and other illnesses affecting the lungs, throat or sinuses. By controlling susceptible bacteria, it helps relieve symptoms like coughing, difficulty breathing, and thick nasal discharge.
  • Cephalexin may also be used short-term to prevent infection following surgery or dental procedures. In some cases, it is prescribed to clear up infection before surgery can be performed.

Proper Dosage Guidelines for Cephalexin

Your vet will prescribe the specific dosage based on your dog’s weight and severity of infection. It’s important to follow the dosage instructions carefully and not stop treatment early. Even if your dog seems to be feeling better, the entire course of antibiotics must be completed.

  • Give cephalexin with food to avoid stomach upset. You can give the pills directly or hide them in a small treat or spoonful of peanut butter.
  • Double check that you have the correct dosage from your vet for your dog’s weight. The dosage is based on the assumption that the medication is given at regular intervals, so stick to the schedule.
  • Cephalexin can be given for 7-14 days for most minor infections. More severe infections may require 3-4 weeks of treatment. Do not stop early unless directed by your vet.
  • If you miss a dose, give it as soon as possible. But if it’s close to the time for the next dose, skip the missed dose and go back to the regular schedule. Do not double up on doses.
  • Possible side effects include vomiting, diarrhea, and loss of appetite. While usually not serious, contact your vet if side effects are severe or persist more than a couple of days.
  • Cephalexin should not be given to dogs with a known allergy to penicillin or cephalosporin antibiotics. Contact your vet immediately if your dog shows signs of an allergic reaction like facial swelling, hives, or difficulty breathing.
