I am sorry to hear your Border Collie has issues with barking.... I do not think a bark collar will be a good choice for a Border Collie. I have 2 BC's and from my experience with them they are highly intelligent and very sensitive to pleasing you. Like other suggestions I would stay with positive reinforcement. I know this can be frustrating because I have been there with one of my BC she is not a barker but she was destroying things and I finally found out what she was needing and it so happens she has strong herding tendency so after buying her some chickens the destroying habit stopped and now she happily takes care of her chickens and is a very good herder and I never taught her how. So I think if you can figure out why she/he is acting this way you will be able to solve the problem. Wishing you and your BC the best.
