I think because of their build, bulldogs do tend to pull on the leash. I've had huskies, and they tend to pull a lot too, but a bulldog is just built low to the ground and it tends to have a strong neck and chest.
I do think stopping and sitting here and there does help, as does changing direction...to a point, which I'll explain later.
I don't agree that pulling around other smaller animals means a 'strong prey drive', I just feel it means you have an untrained puppy. It's natural for any untrained pup to pull and to gravitate toward smaller animals. It just needs to be trained.
However, I will disagree with using a harness. Harnesses are for pulling against, and the low slung center of gravity of a bulldog is made for pulling. I don't care for any of the 'halti' type collars except after attempts with something simpler have failed. The 'halti' type very easily can get caught on things, so must be removed in more situations than the chain collar.
And I will disagree with the statements about not using a training(chain) collar. Plus I don't think you can use a pinch collar on a bullie because they have so much loose and folded skin around their neck.
I don't think that 'if you don't know how to use a training collar, don't use it', is advice I'd give. Instead, I'd advise to learn how to use it, and I think with a bulldog you will need it.
I agree with the advice that 'it's very hard concept', but that the person can't pull if he doesn't want the dog to pull....to a point. There is a point beyond which the dog trainer DOES have to pull on that danged leash, but with a caveat. 'PULL' means a steady, unrelenting backward pull, a YANK or a SNAP is a very, very different thing, and that is how you use the lead and training collar to get a dog to heel without HIM pulling on YOU. The bottom line is that you don't use a steady TRACTION, you use yanks, snaps and jerks of the collar. Oh and I know...how many people feel that's 'mean' and 'cruel'.
But the fact is, you pull steady on that leash, you have a DOG that pulls steadily on that lead. You get what you make. The TIGHTER That leash constantly is - the more the dog wants to fight other dogs, lunge at little animals, and the MORE of a pain in the keister he is to walk on a leash!
The same advice is often given with horses, 'it takes two to pull', and many people take that to mean they should NEVER do anything at all with their hands and the reins should always hang down, but the trick is that you still need to use the reins in training, it's just HOW you use them. With a steady unrelenting pressure to keep the horse's head and neck in position, the horse isn't balanced and it will eventually lay heavier and heavier on the hand...constantly. In other words, you get what you make.
Same with the dog. Don't use a steady, consistent pressure. DON't have that leash be the thing that's holding the dog in position, so that if someone cut the leash, you'd fall down and the dog would shoot forward like a runaway train.
Leash training a strong dog - any training of a dog - is not always a delicate and refined matter of holding a treat where you want to him to go. But it is going to be with quick SNAPS of the leash, NOT a steady pressure. Never thing of HOLDING the dog in position on the lead with a steady, consistent pressure.
The chain collar needs to be fitted so that it is snug, without a long section of chain hanging down. It needs to be put on 'the right way' so that it releases easily(see diagrams of how to put on chain, when it is on right the loose end of the chain does not get hung up, and releases very easily.
The trick is in how the chain collar is used, which takes an awful lot of attention on the trainer's part. He has to be focused constantly on the dog and his own position and what he's doing. Most people CANNOT carry on a conversation while doing this, at least not at first.
It is as if you always want the clip of the leash to HANG DOWN. Not because the dog is allowed to wander anywhere, or even within an 'allowed' area ('directed heeling'), but because the dog is guided into position, NEVER by a steady pressure, but by quick snaps of the lead. The collar should tighten quickly and release just as quickly.
Instead of HOLDING the dog in position by your leg with a constant pressure on the collar, you actually use your chain collar with a quick obvious snap - tight and immediately loose - when the dog is out of position.
Treats MAY help, but only when the dog is not distracted. And some dogs refuse treats during leash training. That MAY be due to stress, or it MAY be because that is just how that dog things - look at the whole dog - tail, ears, head carriage, to determine if it is really stressed.
Train the dog at first in a small, distraction free area, and don't 'graduate' him to walking on the sidewalk or street or field until this training in this less difficult area has gotten solidified. Get your treats and put them in your left hand, the dog is heeling on your left side(treats are a bit awkard to give with a shorter dog, but do your best). Don't ever walk the dog in any other position, but in heel position. Don't say 'oh, we're not training right now' and let him wander or let him walk on the right or in front of you. Ever.
I've never found 'directed heeling' (giving the dog a 'zone' he can be in during early training, because we don't want to 'ask to much at first' or want to teach heel 'gradually' because it's 'nicer', that just isn't how a dog's brain works). to work with stronger dogs that want to forge ahead or pull from the start. Have one position, one consistent position where the dog walks at your side, from the time he's a pup. If you're tired or not up to training, don't put him on the leash and have him wandering around. Be 100% consistent.
How well the dog heels does not depend on his breed, or his age. It depends SOLELY on how the trainer trains the dog. If the trainer reacts quickly and well, the dog will heel well.
When a dog leaps ahead and starts to pull, give him a leash correction. You CAN change direction...but...What you can do by changing direction has its limits - it can't be to the point of 'tricky' or 'unfair'. There has to be a consistency to everything you do. Suddenly dashing off to one side - it's a little 'unfair'. We don't want a dog to be nervously wondering what unexpected thing the trainer is going to do next. I honestly used to do this, and I did not feel the longer term results were what I wanted. I wanted the dog very loose and relaxed, and really enjoying his work - that comes from consistency.
There ARE times when a full 180 is fully justified. When a dog is completely out of control, he is indeed in need of what an old trainer of mine called a 'CTJ Moment'. I just would not over-use it. Keep it in your back pocket for the worst moments only.
Example, I trained a female bloodhound that was about 4 and 'could not be walked on a leash', she spent her entire day in the garage baying in the dark because the owner could not handle her, and the owner had decided to put her down. Even in a maxi pinch collar, she would come out the front door of the house in a full run baying her head off. I let her hit the end of the leash so hard her body flipped over 180 degrees in the air. So, she took off in the other direction, baying and just as fast. I braced and let her hit the end of the lead in THAT direction. She flipped over just as hard, 100% airborne. Then she walked over to me, wagged her tail, and stood there waiting for me to go off in my chosen direction.
That was it. Done. After 4 years of habits had been established. She was a very smart dog and she learned, but dogs in general have very 'elastic behavior'. We get what we create. The trouble was everyone was so busy being 'nice' to her they failed to get an important point across to her - that she needed to pay attention to what the PERSON was doing.
Whenever you change direction plan a gradual change at first, a wide circle or gradual turn, and call out 'HEEL!' before changing direction, and use that command only ONCE before giving a leash correction (snap of lead). Make the snaps very, very quick and obvious. ONLY make them when the dog is out of position. You have to INSTANTLY stop the split second he is in position.
It indeed takes some coordination to snap the lead and offer treats. With a thick necked, short necked dog like a bulldog, it's important to get him glancing up at you a lot. Instead of looking ahead, focusing on things to play with or chase, he is looking up.
About treats. For years and years, most people trained their obedience dogs to heel - whether Khoeler intended it or not, very, very firmly, with lots of very, very harsh leash corrections, abrupt changes of direction, the so called 'Khoeler method'. Over the last few years, people have started to use more and more treats to teach heel, and the results have been a very different look at the obedience trials. The dogs look very cheerful and happy.
But at the same time, it seems quite a few have gone totally to the opposite extreme - OVER emphasizing treats, and never making any corrections('corrections are so mean!'), so they have a very good heeling dog when they have a treat in their hand and are in a training situation, but the dogs aren't TRAINED FOR DAILY LIFE - for example, I saw a dog fly out of a car door like a freight train, pull like a train all the way to the training area, then hop along joyfully at heel in the TRAINING AREA....and then lunge his way back to the car!
DON'T OVER-EMPHASIZE TREATS. DON'T ever believe that when that cat or bunny jumps up in your dog's face, that dangling a treat in front of him as he accelerates to 45 mph is going to 'redirect' him. Think about TRAINING your dog so he is going to be reliable and consistent in and out of the training session...that means there are times when you are going to correct, even PUNISH him. HE NEEDS TO KNOW THAT YOU ARE THE LEADER AND YOU MUST BE OBEYED. Have a 'ladder' in your mind so that you are always on the first step of the ladder, and you never go up the ladder unless you are very sure you have to. If your dog bites or growls, you get a free pass to go right to the top step on the ladder without any other steps!
Remember, your dog HAS to obey you, ,EVERY time you give a command. So don't give a command unless you are in a mood to back it up!
You can start with holding a treat up and giving it to him while he's seated at your side to start getting him focused on you and on heeling. A lot of trainers use especially tasty treats with pups so that they are very eager to get it and very eager to work for it. A bit of liver especially can be tasty - I used to get freeze dried liver bits - nutritious too, but give only small pieces during heeling work.
A person who competes with his dog in obedience, wants a very, very 'cheerful, happy' looking dog that is GLUED to his leg, looking up every moment, hopping up in front almost constantly, and he is going to emphasize that over everything else, right from the start, to keep that 'happy happy' look, much more than the owner who just wants a safe, obedient pet during walks.
The competitive trainer is quite often going to use a TON of treats, almost constantly, in heeling. That isn't always right for everyone, and it is not necessary, as long as one uses the training collar accurately. Especially an elderly or handicapped person, it is hard enough to use the training collar, let alone give treats constantly at the same time. Besides he may much rather have a dog be very, very quiet and steady at heel, right from the start, and not as tight on his leg.
A person who just wants a dog that's fun to walk at home, may not need to have his dog quite as 'treat happy', constantly leaping up, looking up and tight against his leg. He MIGHT want to train his dog that way just because it's fun to have a dog be like that. OR....He may even want to train his dog to be not so tight to his leg, so if he is carrying something he isn't likely to trip on the dog. All it takes is consistency. You get just what you make.
