Hi, my terrier is terrible for pulling on the lead. I have taken him to obedience classes, which he was realy good in. Everything else is fine, in the house perfect, in the garden perfect, but on the lead he;s terrible.

So I went to my local pet shop and bought him a Halti neck as advised by friends of mine, he was good at first, but then started to wriggle and got out of the thing. Its the right size for him, size 1, and it fits him perfectly, its just he can get out of it easily. Whilst it was on, it was great, no pulling or anything at all.

Any advice on this, or has/does this happen to other people?

A Halti 'neck'?  I'm not sure what this is - Haltis are usually called headcollars or halters.......

To solve the problem of wriggling out is going to be tricky training wise, as he's already learnt it's a rewarding behaviour, so you've got to work on making sure he doesn't get the reward, and distracting him so he forgets its rewarding.  The best way of making sure he doesn't escape is to use a secoary link to his collar, either via a double ended training lead, or a special link manufactured by Halti to link the lead to his collar without restricting movement (you should NOT attach the lead to the collar and the halti without such a link, as it can stop the Halti working correctly)

What techniques did you use to try and train him to walk on a loose lead?

Hi,

On a loose lead when he streted pulling, I used to pull him back and say heel. That never worked, so I used to stop dead in my traks and make him wait with me (he does this at roads and the likes, until I say go on), which worked for a while, but then as soon as we started to walk again he started to pull again. He's only a terrier, but he's really strong. Then I tried treats on the walk when he didnt pull, and when he did, we used to stop again. He wont eat any kind of treats whilst out, even liver. Then, when that didnt work I tried tapping him on the bum when he started to pull, to no effect.
I thought after choke chains, but upon looking at them, decided that all they would do would be to choke him, not train him.
So I decided for the head collar. It worked really well, until he wriggled out of the darn thing, lol :D I will try and find one of these doubles leads, so if he does get out, he'll be ok.

Thanks for your help :D

i have a dogmatic head collar which is better than a halti.it doesn't move around and is more comfy for the dog because of its design.you can purchase them of the net and it it is incorrect then exchange it untill you get one that fits correctly.
my pup is a giant breed and i tried all the things you have including clicker training but they all worked for a few weeks then he went back again.
we got a behaviourist involved because he was getting bigger and stronger but not improving much. he is now trained not to pull and walks on a loose lead by my side he still has his head lead and walks differently on a collar (goes backwards) so we keep him to it.
we used a chain on him but it was not used as a means of a collar,it was used just for the noise of the chain moving when he tried to over step me.
within a few weeks of using the methods it worked but you still have to remind him who's boss as he can be stubborn and try it on if he thinks he can get away with it.
some dogs do pull and you need to address it in a firm but gentle way so the dog understands what you expect when out.
we are now on a 25ft lead and learning not to go near other dogs on sight by the means of a curtain word that he understands it is time and training and keeping the top spot with your dog.
if you want any info on the behaviourist i have which come to the house when needed let me know.

Personally I would steer clear of Haltis.  Unfortunately they work as a muzzle.  The more the dog pulls the more it closes their mouth.  Personally I think this is dangerous during the summer time as it doesnt allow them to pant properly.  Also they ride up into the dog's eyes which can cause sores and infections.  We use Gentle Leaders on both of ours and they work a dream.  They do s-xl and you can adjust further to fit your dog.  They need to be fairly tight fitting in that you can two fingers under them.  They work on the pressure points of a dog and calm them down.  They really are worth a look.  They are on the web as well. 

I use a dogmatic head collar on my leo its brilliant, and he can not pull out of it. also when he has not got it on he does not pull as much since using it.

A correctly fitted Halti does NOT work as a muzzle, however dogs noses are all different shapes/sizes, and what works for one dog won't always work for another.....
