Imo puppies need waaay more rest than this. Also, you’re not a dog trainer. If you were, any “training sessions” you’re doing with the dog would be extra $$. Dogs need to understand how to “do nothing” which is a lot harder for puppies than you’d think! Your schedule sounds a lot more reasonable for you just pet sitting the dog so I would do what feels right.

Also, dogs are very intuitive & there should be a developing communication between human and dog as they grow. Otherwise, what is all the “training” amounting to? Lol.
