> I used a crate at night and during the day no more that 4 hours without a break
When a pup has been crated all through the night, it is very unfair to expect it to spend 4 hours in a crate during the day. That is
far too long!
If he is still a chewer at this age, I feel that he has been left without company/stimulation, to get into such a habit.
I honestly feel that, at 2 years old, he is going to be distraught at lengthy periods of being confined when he has no experience of crates.
