Honestly, Jess, it would be fine for some dogs. Sassy LOVED her crate and did not mind it in the least bit. She slept in it willingly more then her bed, etc. BUT she was NOT an active dog in the least bit either. But for a high-energy dog who needs stimulation it would NOT be a good idea. Did you ask the lady if she would participate in agility or flyball with him? I mean, if she was willing to take him to the dog park after work, really long walks, etc and on the weekends take him to flyball or agility then I would consider it but you can't totally trust she will do this. If I were you I'd do some serious questioning and if she still appears to be iffy on the idea then don't persue it any further.
