Why your dog isn't the age you think

Nah you're looking at this from a completely different perspective than the original 1 - 7 years analogy does. the whole idea of it, is that on average, a dog will live about 1/7th of the life of a human. that's all it means lol. we estimate their age like that because it's easier to go "if he's 10 that's like someone who's 70, so he's getting up there" than it is to actually try and quantify aging as a set number. because it's impossible to really quantify aging, as everyone ages differently based on their lifestyle.
