Dog help for border collies?

Border collies are working dogs. They will try to round up little kids and can nip them to try to make them move. Its there nature you cant really stop them. Also they can jump VERY high. My fences are 7ft and they can still jump them. Also if the fences have gaps or its bush I suggest you chicken wire it they are escape artists. They are very intelligent and if they find a way out you need to fix it ASAP as they will try to get out through it again. They need lots of play time so be prepared to be throwing a ball for them for hours everyday. They need brushing once a week.
