Dear /an/,

i have a 7 month old crate trained doggy.
He does well in his crate if he was excercised enough beforehand. However, i want to increase his moving space during the day, by letting him out of the crate to the whole apartment. However when i leave, and he is not crated, he starts crying, and won't really stop.

Should the same approach be used as with the crate training, or i am better of just crating him anyways?
