We bought two books on border collies - and this is the easier to use and it is clearer in its instructions. It is interesting to note how the two books, written by experts, contradict each other on such vital issues as feeding. Still, this is a useful book to have around as a reference.
We bought two of these gates, to keep our rescue Border Collie within certain rooms in the house for the time being. The height of the gates prevents even an athletic young dog from hurdling them and investigating rooms that are out-of-bounds for the moment. The gates were easy to install, are easy to operate and they do their job well. I can recommend them.
