There is a third head collar and that is the Gentle Leader. We recommend and sell this item over the Halti and Black Dog simply because we find the dogs have a harder time getting it off their face.
All dogs will resent the head collar when first put on. Like men made to wear a tie for the first time - it is restrictive, constrictive ( tight around the neck) and at first, uncomfortable.
But we all get used to wearing our ties and at the end of the day are rewarded by being able to take them off. When I retired I rewarded myself by cutting every last one of ties in half.
If used only as a training tool, a head halter can be used to teach loose lead walking. It needs to be used only when you go for a walk and comes off the minute you walk back in the door.
I have a wolf hound in at the moment and on a flat collar he has me skidding down the alley way. Put the head collar on and he is meek and mild.
