That is too much time for any dog in a crate, even though you are having someone come in 2 times a day, where will the dog sleep at night in a crate. I will make some people mad, but why buy a dog if your going to crate her the whole time. As a breeder this is very sad, and I personally wouldn't sell to someone that crates all the time. I don't mean to sound harsh, but why have one buy a fish.
