Why your dog isn't the age you think

i kinda feel like DUH!
i knew this as a kid.

1) a new born of both species are kinda different.
2) teething happens at different ages
3) walking different agez
4) the ability to communicate and "maturity" of conversation

5) arthritis, being tired all the time, and other old type indicators

all in all most people can see the spike in growth of a puppy to full sized dog. (even though some one year old dogs still have baby features. like energy levels.)


edit:
also also the multiply by 7 thing dont work for ALL dog breeds. 
cuz youd have to factor in theage of mortality.
smaller dogs up to 15 at the lower end up to 20ish years on the higher end.
whereas older dogs are 8 ish on the earlier end and up to 15 on the later end.

i didnt do all breeds so get with a vet to verify it but basically a chihuahua lives up to 20 years and a mastiff would be 13 to 15 years.

now of we went nerd mode and divided 85 by 15 (5.6666) and 85 by 20 (4.25).


i used 85 as the average age of death for humans.
