Most dogs sleep ~16 hr /day (which is good as they sleep more than you do - unlike really youngin's)
Chesapeakes apparently like to bar their (really big lookin') teeth and take exception to unknown dogs and people. Though this dog is basically gentle with a household cat and yard squirrels and deer, she could easily go rogue. I wouldn't trust her with an infant.
My previous dog (a full field Lab) seemed quite gentle until at age 3, she took out two groundhogs by shaking even though she was commanded to drop them.
Apparently dogs are dogs.
Dingos apparently are a whole 'nother case.
“... took out two groundhogs by shaking even though she was commanded to drop them”.
My SIL is a vet. She told me that many loving dogs will attack and kill rabbits, ground hogs etc... especially if their master is nearby. Why? The dog is protecting the master. Sounded nutty to me until our dog killed a rabbit (quickly and efficiently) because the rabbit got too near my FIL. He, in essence, was protecting Pop-Pop (who secretly buried the rabbit because he thought it was upset me). So, yes... dogs are dogs.
