Goodogu - it is a GSD, not a pittie, and she goes after anything with moving wheels - so yes - we'd like to break her of it. Thanks!

A female GSD, how old is this Dog? Did you raise it? Did anybody run over it's tail with a stroller or wheel? I'd setup a situation with someone rolling a wheeled thing through path, while she was on lease. When she goes for it, correct her, if she doesn't go for it praise her for doing a good heel or sit or whatever.

Test 2 will help when you are not around or off lease, the next test requires a long line and the same situation. With the same results, in order to praise her this time you need to roll the stroller or find away to time it so when the stroller past and she stays put or don't act aggressive you praise her.

Aggression toward dogs, is another thing but the setup is the same. You have to try to get them use other dogs and animals. Some animal aggression will always be there, I've seen poddles kill mice and squiriles, we have to remember these are dogs.

My GSDs won't go after rabbits or squirles on lease, but my Rottie/Pit its hard to call her off.
Now off lease anything that runs is fair game to them. So even their good behavior on lead, is just a show.

What do you think that has to do with the problem of chasing things on wheels?

The question about did she encounter a bad experience from a wheel, being rolled by or on her, was just a probe. She did not raise the dog so we don't know why it has an aggressive reaction to wheels and animals.

Laureen
I think if you try those two test, you maybe able to crub some of these aggressive actions. Is she a fairly calm dog? Does she seem confidant and unafraid of new people and sounds? You did say that this only happens if the wheels are moving right?

Laureen,
A similar situation was touched upon in a previous thread. Your bitch is expressing prey drive in her desire to chase and bite moving wheels, people, and animals. She has the drive, but it hasn't been channeled to the appropriate prey item. She's choosing the prey item, and you need to make the prey item that YOU want her to respond to somehow more interesting and exciting for her (in addition to stopping her behavior toward wheels and people and animals!!!!!). Have you (and this goes for Stoner too) tried the ball on a string that Ed sells?

In addition, I'd suggest perhaps crating her for a couple of hours, then take her out with the ball and string. Don't take her where she can choose to focus on the other things, but take her somewhere with no distractions, where the ball and string is the most interesting thing around. If she doesn't respond, back in the crate for a while. Keep her environment as free of wheels, skateboarders, and other animals as you possibly can, and really have fun with that ball on a string. A big part of it, to the dog, isn't just the prey item (toy), but it's also how YOU behave. If YOU love the ball on a string and have a great time with it, she's more likely to want to get in on the action.

Good post on the crate and ball and string. Also, let the dog watch you playing from inside the crate and let her see what a wonderfull thing that toy is. Frustration builds drive.

Oooh, I forgot about that! Especially if you play with another dog in front of her, while she's crated! That'll drive her nuts!!!!
