How OTC Dog Antibiotics Work
These over-the-counter antibiotics for dogs use the same active molecules found in vet prescriptions—only the labeling and weight-specific dosing guidance differ. Spectrum options cover skin infections, UTIs, ear infections, kennel cough, hot spots and more. Learn the science in our Dog Antibiotics 101 guide »
Safety & Dosage Tips
- Follow the 5 mg per lb guideline (or product-specific chart) for Amoxicillin.
- Give Doxycycline and Clindamycin with a small meal to reduce GI upset.
- Finish the entire antibiotic course—stopping early fuels resistant bacteria.
- Store capsules in a cool, dry place – 68–77 °F (20–25 °C).
Can I buy dog antibiotics online without a prescription?
Yes. Federal regulations permit OTC veterinary antibiotics for companion animals. Our products are labeled for canine use and ship directly from a licensed U.S. facility.
Are these the same as human antibiotics?
The active ingredient—e.g., amoxicillin trihydrate—is identical USP grade. What changes are capsule size, flavoring, and the dosing chart tailored to dogs.
What if my dog is allergic?
Stop treatment and consult a veterinarian if you see hives, facial swelling, or breathing difficulty. Alternative classes like Dog Sulfa may be recommended.
