With Dylan, I'm not worrying about him and toilet training, he is really good and sussed it quick. Its just his barking. We have the crate in the corner, so two sides are covered - then the top and front are covering in a fleece/blanket - so only one side open. If the blanket doesnt cover even one corner (we have to tuck it in) Dylan barks the house down!
I have no idea why he can only handle one side open and not the other..so for ours, its going to be a while before we move him into a bed - if we ever do so.
If you feel like you can trust yours, try it for one night.. each dog is different
he might surprise you
