Chasing fast-moving objects triggers a dog's natural hunter-prey instinct and is an extremely rewarding behaviour for some dogs.
However, chasing can also result in serious problems if the target becomes bikers, runners and skateboarders in the park rather then a tennis ball or other dogs. Here, prevention is better than cure. Once dogs develop a strong chase habit it can be very difficult to stop it.
- Make sure your dogs is well-exercised before you practice.
Master your RECALL and manage your dog's response to its name as a way of getting attention when you need it.
Reward your dog with high-value treats every time he or she comes back to you when you call them - practice without distraction first.
If your dog shows interest in chasing runners or cyclists, keep him or her on a long training leash in those busy areas where they are most likely to meet the object of their chasing desire and practice getting your dog to focus on you.
When your dog's chase object approaches, catch and maintain your dog's attention and keep rewarding them handsomely.
Practice the SIT and STAY commands while the jogger/cyclist passes.
Repeat this exercise and over time your dog will associate cyclists and runners with being rewarded for staying close to you, instead of rewarding themselves with a game of chase.
Teach your dog that being around you is more fun and more rewarding than chasing; play with them instead (fetch is a perfect outlet) .
Get a friend to run or ride a bike, while you practice your focus and your recall.
