<human>: Can you give me a shortened version of the text?

My girlfriend has a 10 month old American Eskimo. In the last 2 months, we have found him getting more and more aggressive when he is placed in a crate or when he is tied to a stationary object. We've been trying to train him to behave while crated, but our ability to treat him for good behavior is a struggle. During the daytime it is fine, but at night, he will bark relentlessly until he is released. When crated, if you walk by him, he will snarl and has even started to snap when a hand goes near.

I've been reading articles about Dog aggression and establishing dominance, but we are also looking for some strategies that can be used immediately. We are also looking for professional help as well, but funds are not very high to pay someone.
<bot>: 10 month old American Eskimo hates being crated or tied to a bench. Getting more aggressive and snapping now. Tips appreciated
