In some ways, it's been difficult to do certain things with Krypto, because as I like to say, 'He was raised by wolves!'
He wasn't really, of course, but he and his siblings were their own company most of the time, punctuated by humans feeding and cleaning their area a couple of times a day, only.
So, they didn't care about being pet, or anything, at first.
On the other hand, he had no bad experiences with people, which was nice for a pound rescue. They didn't even have the usual 'pound trauma' of many of the pound rescues that I've had over the years did. They had their own room, and knew nothing else from birth.
How interesting that Charlie doesn't care about bugs. Krypto steps on them, or eats them. *sigh*
Charlie has interesting behaviors when it comes to other dogs. I guess that it works for him.
No, a loud bark is not a great thing indoors.
