I don't think he thinks of himself as a puppy actually. I have wondered if Addie took to him so quickly because she was intact and she felt maternal towards him though? She was fascinated by him, and Great Dane pups are big so he was the right size for a newborn Dane pup! She is the more outgoing, readily accepting of other dogs, dog. I watched a friend's American Bulldog for a week once and she immediately was playing with him. Now THAT was a rambunctious week!! He was 6months old and all big puppy! I was really glad when he left!! lol!!
Just like I don't think the Danes are always aware of their size, I don't think Tad is either.
Correct.
Dogs don't have the same kind of "size awareness" as we humans do.
They progress in life, and become adult dogs, no matter what size they are.
Other dogs sense this as well, they don't treat a small dog as juvenile dog. Once the dog has grown balls (literally speaking
) other dogs will treat the dog different.
