9 hours is a long time to leave a puppy home alone everyday. especially when you first adopt him.
Agreed. That is a long time for a one year-old to be on their own in a crate.
I was lucky. When our dog was first home, I worked from home and was with him all day everyday for the first year of his life.
For less than one year-old dogs there needs to be some interaction or activity every 3 - 4 hours. After the 1 - 2 year mark, they can be left on their own for much longer.
Of course now we have a senior citizen at 12 years old who other than his very short morning and evening “walk” basicaly sleeps all day - and he seems perfectly fine with that.
