very good advice, I just wanted to add that there are 30ft leads that you can buy and they are very effective to tech this command and still have the safety of a leash being on the dog. It does work easiest with 2 people, at first i started out about 10 ft apart, then 20ft.. then moved to 30 ft.. needless to say come has always been a fun command for coco so I think I got it easy with her |
