I cant help you with make or model but i did build a pool for a Dr and his wife and they had one and it did work, you can also use a training collar ,, i know labs are a little hard headed but they are great dogs and if you are going to be out when he is get a collar, start low on the settings and just go up till it gets his attention, after awhile all u need to do is put the collar on, they are smart and figure it out fast
