Frequently Asked Questions
Is this a substitute for veterinary advice?
No. This calculated dosage cannot replace actual medical advice and cannot serve as a sole source of clinical decisions. Contact your vet with any doubt, and never give your pet any human medication without veterinary approval.
What is the standard dosing rate?
The calculated dosage is based on NOAH (National Office of Animal Health) recommendations, equal to 15 mg per kg of body weight per dose, given twice daily.
What should I watch for after starting cephalexin?
Monitor your dog closely after the first few doses. Some breeders have reported weakness or lameness in certain breeds with off-label human formulations, and dogs with allergies or kidney issues need particular caution -- always discuss your dog specific history with your veterinarian first.
