How to stop my multiple dogs from barking at other dogs in the car?
Thank you for using Petco Pet Education Center, formerly Petcoach. It sounds like you have been doing some one on one training and small groups, and that has been going well. If that is the case, I suppose I would try adding one dog at a time, and not moving to more dogs until the behavior is controlled. If 2 or 3 is going well, then add a 4th, and change who that 4th dog is. Perhaps you will find that there is one particular dog that is the instigator, and you can work more one on one with that dog. Make sure you are telling them what TO do (i.e. sit, lay down, stay, etc.) instead of what NOT to do. Give them a job, and reward them for doing that job. Have patience, and keep working at it! I hope that helps.
