How to find the right Dog Medications AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Dog Medications
- Prescription vs OTC
- Heartworm preventives, isoxazoline flea/tick drugs, NSAIDs, antibiotics and allergy drugs need a veterinary prescription. These need a diagnosis, weight-based dosing, and for heartworm a negative test before starting.
- Weight band
- Buy the box that matches your dog's current weight band, and never split topicals between dogs. Dosing is weight-banded; underdosing fails and overdosing risks toxicity.
- Species-specific labels
- Use only products labeled for dogs. Keep permethrin dog products away from cats. Permethrin spot-ons are often fatal to cats.
- MDR1-sensitive breeds
- Collies, Australian Shepherds and related breeds need vet guidance on ivermectin-type drugs and loperamide. The MDR1 mutation lets these drugs reach the brain.

Questions
Do I need a heartworm test before starting prevention?
Yes. Starting a preventive in a dog already infected can cause a serious reaction, so vets test first.
