I just wondered what is the average time you would leave a puppy in its crate? The one I am currently looking after is 8 months old. She doesn't seem to mind it at all. She never cries even though I am a dog sitter and she has only been staying with me since Saturday. I leave her in it at night. Put her in it when I go to sleep. Tonight it was 10.30 and get up with her again at 8am. Then during the day I occasionally pop her in for the odd few hours if I have to go out. Also during the day do you tend to cover the crate with a blanket? I have been doing it because I think if she looks out and sees I'm not there she may feel lonely. I tend to walk her lots and then put her in the crate for a nap during the day time. It does make me feel a bit guilty. I just hope she's happy .
