Live now: Can Dogs Eat food safety guides

Our "can my dog eat this" guides are live in the Can Dogs Eat section. Every verdict is checked against at least two authoritative veterinary sources, with the sources named on the page and emergency numbers on every guide.

How our calculators work

Feeding math starts from the standard veterinary resting energy formula (70 times body weight in kilograms to the power 0.75), adjusted by life stage and activity. Cost figures use the price and care ranges documented on our methodology page, and every result is labelled an estimate, because that is what it honestly is.
