There are two aspects to this behavior: 1. having a person walk by the dog and 2. walking the dog by a person. Work through both.
Practice on several other people individually, increase level of difficulty (may be from friends to strangers or the reverse depending on the dog’s level of sociability.)
1. Start by walking by one familiar person at a distance, decreasing distance at each pass. C/t for any loose leash, or focus on you. As you get closer, you dog may tend to move towards the person. To keep her near you, increase your rate of rewards. Practice on several other people individually, increase level of difficulty (may be from friends to strangers or the reverse depending on the dog’s level of sociability.)
Increase number of people to two, then three.
2. Next ask one person to walk by you and your dog at a distance, then closer. If as they approach, your dog tends to move towards them, try using rapid fire rewards (c/t done in quick succession to keep your dog's attention on you. Decrease the speed over time as they approach and she keeps her focus on you.
C/t can be used as an interupter and to refocu your dog on you but be careful not to wait too long as you might unintentionally be rewarding moving toward the person. Timing is key here. Better to click to soon (for focussing on you) than too late in this circumstance.
B. People Wearing Different Clothes
Use people of different ages, sizes, clothing (hats, sun glasses, mustaches, carrying bags, add a pillow for a big belly, draped clothing like saris, etc)
C. People Carrying and Pushing Things (sound and motion elements)
Start with one person and one object held stationary. Then moving object a little, then more, then faster. Add sound (such as bag flapping in wind or umbrella popping open)
Train for canes, strollers, wheelchairs, skateboards, shopping carts, etc.
You may need to do some separate training at home first getting your dog to target then learn to push large children’s plastic toys, allowing your dog to interact with a skateboard (motion and sounds) etc.
D. Training for People Carrying Food
Start at home by training “leave it” cue for food, toys and other objects you don’t want your dog to touch when out in crowds. (see Sue Ailsby's Training Levels for a detailed description).
Ask a friend to hold food in their hand and cue leave it etc. Then hold it so it is visible. Then closer and closer to dog nose level. Place yummy-smelling food in a bag and ask a friend to walk by the dog. C/t for keeping the nose away, then for focussing on you.
Use adults, teens and dog-safe children.
Ask dog-friendly strangers to do the same.
E. Adding More People
Next, visit an outdoor public event where dogs are allowed and you can easily choose your distance from the crowds (check out your local community event listings in the newspaper or on-line).
Walk the periphery.
Walk a few steps in and out.
Walk further in and out.
Walk in longer or across to other side.
Spend more time in that environment-bring a chair and sit for awhile.
F. People with Dogs and Other Animals
Train for the animal first using the same process as for moving objects before training for people with dogs (or other animals) in a crowd.
Train each animal species separately –horses, cats on leash, ducks, etc.-whatever you know you are likely to face in your everyday life. See blog post 41C
G. Go to Events or Training locations Where People Have Their Animals With Them
Start with a single species event such as a dog trial, then a horse event. A 4-H Club Display or County Exhibition can be a great place to test/practice the level of distraction your dog can tolerate after she has had much training.
Start at the periphery as for crowd events. Give yourself and your dog lots of space to escape and know where physical barriers are in case your dog goes above his threshold.
Move to small groups at periphery, before moving to other areas of more dense people and animals. Err on the side of keeping under threshold.
Be Proactive, not Reactive!
Be prepared for any situation and always have a way out planned ahead of time!
Anticipatory Training is the Best Defence
Once your dog and you have worked through the process of training for different kinds of distractions, you will be ready to take on anything. You can use the same general approach if something unforeseen pops up and each new challenge, your dog will respond more quickly. Mix and match the approaches as needed.
For example, one woman in a wheel chair with her service dog was at a horse competition and found herself just above ground level with all the horses running directly at her and her dog, then turning to the side to take a jump. For various reasons, it was not possible to request a different seating location. Her assistance dog was so distracted at first she was unresponsive to cues and would move to the side each time a horse approached, but after marking and jackpot rewarding calm behavior when the first few horses were far away, then marking and rewarding as each successive horse approached a little closer, the dog was resting comfortably beside her chair about 20 minutes later with the horses thundering nearby, ready to be able to offer her help at any time.
What Environments will you be Visiting in the Future?
Identify the potential distractors in each environment and work through each before visiting. Intend that each of your visits are training sessions and focus on your dog. It may mean you visit the location without your dog or stay at the sidelines to observe at first. Look at each location from your dog’s perspective. Make a list, prioritize as above and pre-train your dog not react around those distractors (expose her to those under controlled settings such as at home, in familiar training environments etc.) It may mean you ask friends and family for their help, you may need to borrow equipment for a couple of weeks or ask permission to go into locations during quiet periods or after hours. Be creative and resourceful in gaining access to places. If you ask, and explain what you plan to do, often people are willing to help, if not professionally, at least personally.
