Frequently Asked Questions

Why is accurate weight important?
Pet medication dosages are weight-dependent. Small errors in weight can lead to significant under or overdosing, especially for smaller pets.
Can I give my pet human medication?
Never without veterinary guidance. Many human medications are toxic to pets. Even safe ones require different dosing than humans.
How do I give liquid medication?
Use a syringe without a needle. Insert into the side of the mouth, behind the canine teeth. Squirt slowly to avoid choking.
Why is this calculator for reference only?
Individual pets may have conditions affecting drug metabolism. Only a veterinarian can determine the safe and effective dose for your specific pet.
Can I mix medication with food?
It depends on the medication. Some must be given on an empty stomach. Check the accompanying instructions or ask your veterinarian.
