I was looking on Craigslist and found this dog kennel, for $175. I have been wanting to give my russians an upgrade and was wondering if this would be good, and any adjustments I would have to make to it to accomodate them. I probably would have to make a covering, and something that doesn't allow them to see through for a foot or two high. Also, does the door area look big enough for a russian to squeeze through? Thanks in advance for any help.
