Dogs grow up fast. You’ve probably heard phrases like, “ageing like a dog,” or “in dog years” and wondered why we say things like that? Well, that’s because one year for them is equal to 7 years for us. Dogs have an average life span of 10 to 13 years. For us, they leave behind memories of a lifetime to cherish.
