Having a big problem when I walk Baby. When he sees a car, he will start barking and try to attack the car. Eventually he will go into the red zone and bites me. I have tried picking him up so that he can't get his feet on the ground for leverage, tried distraction with food and also a toy. So far nothing has worked! I have thought about a shock collar but not sure about it. I had a bad back so his lunging fits aren't good for me.
Is this a puppy you raised, or one you acquired with the problem? What is your level of experience with dogs? I would not try to pick up the dog, or put my hands on him if he's in a frenzy, you can get bitten and he will not even realize it's you he is biting.
Bite? This is not good.
Suggest you find a dog behaviorist -- ask a good vet for a referral. I had a German shepherd who was determined to bring down a car or a truck by the oil pan. Some dogs just have an atavistic instinct to go after anything that invites chasing...which is anything on four wheels, two wheels, three wheels, or legs.
Picking up that dog when she was a pup, so as to carry her away from the neighborhood feeder street where she was flipping out over the 5 p.m. traffic, put me in the hospital. If you already have a bad back, even a 25-pound dog can do some serious damage. Get a trainer! The guy I hired quickly taught me how to get the problem under control.
I just saw a video of Zak George on utube about stopping a dog from lunging at cars. Check out some videos. Mainly you have to work up to this slowly. Teach a watch me command and gradually work at using treats to get her to focus on you then from a distance you can introduce getting nearer to cars. The frustration and excitement she feels is why she turns on you. The idea is to catch her in the teaching moment before the excitement.
Yikes! That is probably going to take some deconditioning to the stimulus of the moving cars. Can you walk in places where you are away from cars, or far back from them? If you are in a very urban environment this will be tough. As best you can work away from the car stimulus with positive rewards for looking at you instead of the car, or doing anything else that is non reactive. You will have to slowly build up his tolerance to being close to a car and not reacting. If you don't have a "look at me" command, teach this at home first. Also, have him sit, shake paw, touch hand - any simple trick that makes him get his mind off other things and focus on you. Give high value treats and lots and lots of praise. Teach the tricks in the house first, then take them outside in a 'non-reactive' environment. As he gets more comfortable, move closer to cars but still far back. If he starts to react, take it back to where you were successful. You may be taking this in inches over several months, but you have to try something. Enlisting a professional may be good also. Good luck!
