What crate size would you suggest? Mom is 22.5/45lbs, dad is 24.5/62lbs. Mom is 22.5/55lbs, dad 22.5, 55lbs. Planning to get 2 different crates. Wanted to use the same crate from puppy hood til full grown using a divider. I'm seeing ones that are 42, 48 long but only 30, 33 tall...is that really tall enough?
