Thanks very much for the information. My sister had a border collie, so we know how smart they are. Amazing dogs! I know that the Shelties are similar in some ways, so we will have to make sure that we can keep him/her busy and happy. We want one badly, but need to be sure we can take care we have the time to care care of one properly. We have some decisions to make... Thanks again!
