I don't use collars on my dogs for fear of damaging their trechea. I use a harness. I've been talking to my pet store,they also recommend a prong collar,which prevents pulling,it's better then a choke collar.I've also had Tigger when she really wants something almost slip out of her collar,no matter how tight it is. A harness is the best bet for her.
a slip choke collar is not very effective. the dogs can still pull on it and that type will damage the dogs trachea if it is not used properly. i use a prong collar on my dogs. alot of people think this collar is cruel but it isn't. it was designed to put equal amounts of pressure around the whole neck not just one area. it also mimics the pressure a mother dog puts on her pups when she needs to discipline them. if used properly - a quick pop and release - it is very effective and does not harm the dog in any way. also a halti collar is very effective also. it is a nylon halter similar to a horse halter that when the dog pulls it turns their head towards you. this is a very good toll also. i used it on my chow mix but he is a very dominant dog and he refused to have this over his mouth so he pawed and chewed at it til it was destroyed. i went through 3 of them before i went to the prong. now after being trained on the prong not to pull i can walk him on a regular nylon buckle collar and he is fine.you should have an obedience trainer advise you how to use any of these collars effectively and properly though.
when walking or training a dog, i have used the gentle leader. it is not a muzzle, the dog can eat, bark fine. this works very well with any type of pet, small or large. takes about 2 days for them to get use to. you can find them at most pet stores for about $25. good investment.
A trainer told me harnesses are useless on dogs that pull, all they do is encourage them to pull more. I've used choke chains and prong collars on both my dogs without any ill effects, when used correctly they can work wonders. The gentle lead head halters can work on some dogs, but are useless on short muzzled dogs like pugs and boston terriers, my Akita went nuts when we put one on her so we didn't use it. Head halters are also useless on dogs that refuse to be coased along and just sit down, a harness works best on those dogs. I guess what i'm saying is what works best depends on your situation.
I would suggest a harness or a gentle leader. iHATEcats2404 - the collar you are talking about is called an e-collar which I would not recommend to anyone. If not properly used they can cause damage and aggression in your dog.
I only like choke chains because, when they are used you can be sure the pet will not be able to slip it and escape. But for teaching not to pull this is not effective. Prong collar can work for dogs that may pull, it depends on the dog.I actually use it occasionally with my frenchie. I use flexi leads and they basically run all over the place and smell everything. Sometimes he forgets howfar he can go and I will get the occasioanal tug and I may drop the end of the lead. With the pronge he pays more attention to where I am, and doesn't pull. With a your breed you could easily start to train him on the Halti or Promise collar. But lets look at why dogs pull in the first place... Dogs pull to get to what they want, if they make it to it, then thats their reward. So that means to them they were rewarded for pulling towards that item, will say...some goose poop..ha ha...And they got it,.... so you need to change the lesson, now while the dog is young...When the dog is pulling on the leash stop and freeze, don't walk.....When he stops pulling and the leash becomes relaxed start to walk.........As soon as he pulls again..freeze, don't walk.....when the leash becomes loose start to walk again,,,.....repeat, repeat, repeat. He will learn over time that only when the leash is loose do I get to smell that bush or eat that goose poop heh heh. When the leash is loose talk to him in a happy voice....When he pulls say nothing!!..........I hope you try this a few hundred times, ha ha hope it helps.......
"I hope you try this a few hundred times, ha ha hope it helps......." when i took my puggie to puppy class the trainer said with his newfoundland he did this and it took 6 months to get out of the driveway, BUT his dog doesn't pull at all now! it works.
