It is commonly thought that a dog’s age is roughly calculated as seven dog years for every human year. However those with dogs will know, that it really does depend on the size of your dog when calculating how old they would be in dog years.
This cool graphic shows how to calculate your dog’s age, dependant on it’s size.
Based on this, it would make Archie 45 in human years, Lola 39 and Milo 31!
It is nice to see that I’m not the only thirty-something year old in the house. :)
