Most dogs enjoy chasing things, with cats, cars and people being particular favorites of theirs. Dogs generally see this as something fun to do, and don't mean any harm by it, but, the fact is, that by chasing they invoke fear in others and can cause unintentional accidents.
Allowing your dog to chase anything is an irresponsible thing to do. Behavioral problems like chasing are more than just annoying. Solving this problem is possible though, but it will take some effort to correct.
Different breeds of dogs have a stronger instinct in chasing than other dogs but, whichever you breed you have, the behavior can't be stopped by simply yelling at or hitting your dog.
The very least that you should is not let your dog be in a situation that allows it to chase in the first place. Keep him on a leash or in a fenced yard if necessary. Keep your dog and those in the surrounding area safe until you learned to predict his behavior and you have him trained to obey your commands.
To prevent them from chasing an owner needs to understand his dogs cues. It is common for dogs to give some indication, such as a prolonged stare or a lifted leg, before they set off after something. Once you know what it is that your dog does, you can act before it does. You should be able to find this out fairly quickly as dogs are creatures of habit.
The obeying of basic commands is necessary for a dog to stop chasing. At the very least, your dog needs to respond to two - sit down and come here. Once your dog understands these skills it will be easier to stop him from chasing.
So, lets now look at how to train a dog to do what you tell it to do. First obtain the toy or treat that it likes the best. Place your chosen item 10ft from the dog and wait for it to start approaching it. As it starts to move, command it to either sit down or come to you. When it obeys your command, speak in a warm tone to it and let it have the toy or treat.
After having done this with just you and your dog, ask a friend for their assistance. Have your friend jog by you while waving a toy or treat and see what the dogs reaction is. Should the dog start to chase then give a firm command to it to come back to you or to sit down. Once it obeys your command, give it the reward.
This might take some time and patience, but your persistence will pay off. Remain positive and determined and you should have the problem solved within a week.
