The problem
59%
of dogs at the vet are above a healthy weight

Most owners can't tell if their dog is overweight.

59% of dogs seen by vets are overweight or obese. But only 39% of owners say their own dog is. A few extra kilos are easy to miss and easy to normalise.

Could you spot the difference?

Most people can't from a photo alone. That's exactly why the check takes the actual shape of your dog into account, not just a guess.

1.8
Extra years of life

In a 14 year study of Labrador retrievers, dogs fed 25% less than their littermates lived a median 1.8 years longer (13 vs 11.2 years).

Why weight, not age
It crept up slowly. It can come off the same way.

Weight is the one thing about your dog's lifespan you can still change. Small, boring changes are what work.

FAQ

Before you start

Is this vet advice?

No. DogSpan gives you a research backed starting point, not a diagnosis. Always loop in your vet, especially for older dogs or existing conditions.

Does it work for mixed breeds?

Yes. If there's no exact match, we use the closest comparable body type and adjust from there.

What if it's not right for my dog?

Email us within 14 days for a full refund, no questions asked.

Is there a subscription?

No. One time payment. Nothing recurring, nothing to cancel.

How many years are on the table?

Start with their name. Eight questions, then the number.
