A friend of mine has a german shepard that they leave in the backyard while they are at work, she barks quite a bit and my friend had aminal control called on them. I have talked to her about crating her but they don't want to do that.

They enrolled her in a doggie day care, they just started this so I am not sure how it will go but it is probably the most humane alternative for the dog. It isn't cheap though, they are paying $400 a month.
