You will always fit in my heart, little puppy

It is always the big dogs that are determined to stay a puppy and be treated like one lol. My grandma had a Great Dane named Bozo and everyday after my grandmother would come home from work where she was on her feet sometimes 9 hours, that dog would nudge my 5'2 110 pounds grandmother to a chair and insisted on sitting in her lap. That dog was almost bigger than her but she was mama.

I think that they just think "what happened? Everything's got smaller!"

I read on some .org site that dogs only develop to the mental stage of a 10 to 30 day old wolf puppy, and this means dogs mentally never become adults. So maybe they do see themselves as puppies all the time.
