Clindamycin is used in dogs to treat dental infections, skin infections, and bone infections. It is typically available in tablet, capsule, or liquid form and is usually given orally. In most cases, a prescription from a licensed veterinarian is required.
Common Side Effects in Dogs
Watch for these signs and contact your vet if any appear or worsen:
Contact your vet immediately if your dog shows signs of a severe allergic reaction (facial swelling, difficulty breathing, collapse) or if side effects are severe or persistent.
How to Give Clindamycin to Your Dog
- Give with food to reduce stomach upset unless your vet instructs otherwise.
- Complete the full prescribed course even if your pet seems better.
- Store at room temperature away from moisture and heat.
- Never split or crush tablets unless your vet confirms it is safe for that formulation.
- If your pet vomits within 30 minutes of a dose, contact your vet before redosing.
⚠️ Important Safety Reminders
What If My Dog Misses a Dose?
If you miss a dose, give it as soon as you remember — unless it is almost time for the next dose. In that case, skip the missed dose and continue on schedule. Never double-dose. If you are unsure, call your vet or pharmacist.
