Is MyPetMath veterinary advice?
No. MyPetMath is written and built by Malik Khurram, who is not a veterinarian. The formulas come from veterinary references, but a formula can’t examine your pet, know its history or spot an illness. Nothing on this site creates a vet–client relationship.
Why are results only estimates?
Formulas describe averages. Two healthy dogs of the same weight can need 30% more or less food than each other. Growth, age and pregnancy timing also vary between individuals and breeds. That’s why we show ranges and ask you to check your pet’s weight and body condition over time.
When should I talk to my vet first?
- Your pet is a young puppy or kitten, a senior, pregnant or nursing.
- Your pet has a medical condition or eats a prescription diet.
- Your pet is losing or gaining weight without a change in food.
- Your pet is eating or drinking much more or less than usual.
- You plan to put an overweight pet, especially a cat, on a diet.
Do you have medication or toxicity calculators?
No, on purpose. Medication doses and poisoning risk depend on the exact product, your pet’s health and other factors a website can’t check. Please ask your vet about any medicine.
What should I do in an emergency?
Call your vet or the nearest 24-hour emergency clinic right away. For a possible poisoning, you can also call the ASPCA Animal Poison Control Center at (888) 426-4435 (a consultation fee may apply).
