Hello! I have a 12 week old and just got her a crate. It’s a 42” with barrier. I’m not sure how much room to give her in the crate? I’ve set it up to be 14”d x 28”w. It seems like enough for her to turn around and sleep, but don’t want too much room as I understand it could allow her to soil the area. All comments are appreciated!! Thanks in advance! ** I would not leave her in with her collar on - this was just for pics.
