Q. We have a 4 yr old lab-pit mix we raise from 6 weeks.If my husband tries to take hin by the collar and make him go out to pottie he growls.Problem?
A. This is not good behavior. Rather than take him by the collar, call him to come with you. If he's not good about coming when called, you can work on that. Keeps treats on hand to to entice him out and reward him when he does go potty and he'll come to look forward to it. Clicker training is another great way to teach a dog all kinds of things, from obedience to tricks.
Have treats on hand that you know he loves, then simply click and treat. He will come to associate the sound with getting a treat. Start putting distance between you so he has to come to you. Call and click and when he comes to you for that treat, treat him and give him lots of praise. Move to hiding somewhere in the house, call and click. When he comes to you reliably inside when you call, click and treat. When this behavior is consistent, move outdoors with a very long leash. Call and click, if he doesn't respond, give a light tug on the leash. If he takes even a single step toward you, click, treat and lots of praise. Keep doing this until he comes eagerly. Next, try him off-leash in a securely fenced area. Call and click. At this point he should be responding well and coming easily to the call and click. If he does not, go back to the last step he performed reliably and work on that again until he responds well. Eventually, you can start not treating him every time, but still praise him. Gradually lessen the frequency of the treats until he comes just to the click and praise.
Keep training sessions short, ten or fifteen minutes to start, no more than 30 minutes at a time and do it a few times a day. Try not to do it any time he is overly excited so that he can pay attention to you. Always end a training session on a good note, even if it is just getting him to do something he already does well on command. And never, NEVER punish a dog when they come to you, no matter how far they've made you chase them, no matter how frustrated and angry you might be. That teaches your dog that coming to you is a bad thing.
