Hello

When my dog is in the yard, she will bark at other dogs passing. She is a nervous dog and scared of everything. I try to associate something good with another dog passing like a treat but before I can give her the treat she is already running and barking at the dog as it passes. I do not want to use a bark collar or leash corrections. What can I do?

Thanks

Is she safely confined in a fenced area while she is running and barking at other dogs? Or on a leash?
Is the barking a problem for the neighbors?
My first thought would be for her safety.
I have one of these dogs that you describe and I have yet to teach her not to bark, it is just something that she is going to do.
What I have to do is make sure she is safe and protect her from her very own large attitude.

You will never teach a dog to not protect their home. Even the wimpy dogs will stand up and say something when someone comes close to their home. Dogs don't understand that the 5 feet after your fence is not theirs. To a dog.. the fence, the sidewalk and the tree are theirs.

There are other types of collars out there that use correction but are not a shock correction. You could see if she will respond to a citronella collar or an ultra-sonic collar.

You giving her treats thinking that you are teaching to think good things when other dogs pass by is actually telling her that she is doing a good job running the fence line and barking.

Ignoring her.. bringing her inside when she starts up and telling her "no" and meaning it are the only ways to help reduce this problem.
