In Dog Years, I'm Dead

Most people think that one dog year equals 7 human years. If that were true, it would mean a 1 year-old dog(that is able to have puppies) is equal to a 7 year old kid. And if a dog was 15(not an unusual age for a dog) it would be 105 in human years(which is an unusual age for a human).

A more accurate comparison is that a 3 month old puppy is 5 in human years. A 1 year old dog is a teenager of 15. A 2 year old dog is 24. After that, aging slows and 4 human years are added for every dog year. So at 3 a dog is 28, at 5 he is 36, at 10 he is 56, at 15 he is 76. A dog that reaches 20 is considered to be 91 to 96 years old in human years.

So if the oldest dog was 29 years and 5 months in dog years, how old would he be in human years? Certainly over 110.
