Pet Medication Calculator Safe Dosage Calculations
Calculate safe medication dosages for your pet based on weight and medication type. Always verify with your veterinarian before administering any medication with our veterinary-approved formulas.
Safe Pet Medication Administration
Proper medication dosing is critical for your pet's safety and treatment success. Unlike human medications, pet medications must be precisely calculated based on body weight, and the margin for error is much smaller. A dose that's safe for a 70-pound dog could be toxic for a 10-pound cat, making accurate calculations essential.
Our medication calculator helps you understand appropriate dosage ranges for common veterinary medications. However, this tool should never replace professional veterinary guidance. Every pet is unique, and factors like age, health condition, other medications, and individual sensitivity can affect how a pet responds to medication. Always verify calculations with your veterinarian.
Pet medication errors are unfortunately common and can be serious. Over-dosing can cause toxicity, while under-dosing may result in treatment failure and drug resistance. This calculator uses standard veterinary dosing guidelines but remember that your vet may prescribe different doses based on your pet's specific needs and medical history. When in doubt, always contact your veterinary clinic for clarification.
How to Use the Medication Calculator
Get Accurate Weight
Weigh your pet recently and accurately. Even a 1-pound difference can affect dosing, especially for smaller pets. Use your vet's scale if possible, as it's likely more accurate than home scales.
Select Medication
Choose the exact medication prescribed by your vet. If it's not in our list, select "Other/Custom" and enter the prescribed dose per kilogram that your vet provided.
Review Calculations
The calculator shows both single dose and total daily dose. Some medications show a range because vets often adjust within safe parameters based on the specific condition being treated.
Verify with Your Vet
Always confirm the calculated dose matches what your veterinarian prescribed. If there's any discrepancy, call your vet's office immediately for clarification.
Administer Safely
Follow the administration guidelines for your specific medication. Some need to be given with food, others on an empty stomach. Timing and method matter for effectiveness and safety.
Monitor Response
Watch your pet for both improvement in the condition being treated and any potential side effects. Keep a log of when you give each dose and any observations about your pet's response.
Benefits of Accurate Medication Dosing

Frequently Asked Questions
What should I do if I miss giving a dose?
If you miss a dose, give it as soon as you remember, unless it's almost time for the next dose. Never double up doses to make up for a missed one, as this can cause overdose. For antibiotics, try to space the remaining doses evenly to maintain consistent levels in your pet's system. If you frequently forget doses, set phone alarms or use a pill organizer. Contact your vet if you miss multiple doses or are unsure how to proceed with the treatment schedule.
Can I give my pet human medications?
Most human medications are NOT safe for pets and some are deadly. Never give human medications unless specifically prescribed by a veterinarian. Common human drugs like ibuprofen, acetaminophen, and naproxen are toxic to pets. Even "safe" medications like aspirin require careful dosing and monitoring. Xylitol, found in sugar-free gums and medications, is extremely toxic to dogs. When in doubt, call your vet or pet poison control immediately rather than risk your pet's safety.
How do I know if my pet is having a medication reaction?
Watch for vomiting, diarrhea, loss of appetite, lethargy, difficulty breathing, swelling of face or throat, excessive drooling, or unusual behavior. Some reactions occur immediately, while others develop over days. Allergic reactions can include hives, itching, or facial swelling. Stop the medication and contact your vet immediately if you notice any concerning symptoms. Severe reactions like difficulty breathing or collapse require emergency veterinary care. Keep a log of symptoms with times to help your vet assess the situation.
How should I store pet medications?
Store medications in their original containers with labels intact, in a cool, dry place away from direct sunlight. Most medications should be kept at room temperature unless specified otherwise. Refrigerated medications should never be frozen. Keep all medications out of reach of children and other pets - child-proof caps don't always work for curious pets. Don't store medications in bathrooms or cars where temperature and humidity fluctuate. Check expiration dates regularly and dispose of expired medications safely through veterinary clinics or pharmacy take-back programs.
What if the calculated dose doesn't match what my vet prescribed?
Always follow your veterinarian's prescribed dose rather than calculator results. Vets consider many factors not captured in general calculations, including your pet's specific condition, other medications, kidney and liver function, and individual response to treatment. Discrepancies might occur due to different dosing protocols, specific product concentrations, or condition-specific adjustments. Call your vet's office to clarify any confusion. Never adjust prescribed doses based on calculator results without veterinary approval.
