Very nice informative app, but it states enter "your age"? which would be my age (80) and the answer equals 16.5. Confusing to me because I lost the birth record on my Yorkie. As near as I can determine/remember she was 15 as of Nov. last year.Pretty close......

Still a good job on this app by the developer.

All the time I wondered what my age would be in dog years. I finally found this!

Every year to humans = 7 dog years

It's so cool!!

This is totally incorrect and useless! It multiplies years by 7. Everyone who knows anything about dogs knows that their "human" age can't be determined by multiplying 7 by their bio years. Find a "dog age calculator" on Google and you'll find that a 10-yr old dog is only 53 in human years. I'd give this one negative stars if I could! What a waste of time!

Nice screenshot...who's dog is 699 years old?

I think this app is a little simplistic but it's free and everyone should end sarcastic comments. I'm sure a few people would find it handy. BTW, I read there's a new method to calculate a dog's age that factors in the breed. Pedigree's web site has a good example but I don't know the math (not dog age times seven).

Wow. What would I have done if this amazing app had not come along? I think that maybe if I had nothing but crack cocaine laced with battery acid since birth that maybe I would in fact need this program to perform the most basic of math equations. But wow. Fantastic program. It's not every day a developer shines through with such an amazing piece of software to embrace the world. My hat is off to you. =P
