I need your expertise...We got our dog from a shelter and she was one of the loudest dogs there. Over the past month and a half since we got her, she has been great. She is great with people, loves kids, etc. However, she hates dogs. When we walk her, she will bark her head off at the dogs we pass. Sometimes it is like a scared whimper bark but other times she will lower her body and bark real loud. It hasn't been helped that twice on our walks, a dog has run off it's property into the street and started barking/jumping at her. I'm sure the barking is because of shelter life but I want her to be calm with dogs. The houses around us all have big dogs and they never bark. It's embarrasing. I have looked into trainers but they are all about $150 for a private session and all the puppy classes say dogs can't bark and I know she will around all the dogs. Also, she walks on a leash, and sits, and lays down so I hate to waste money on a basic command class. Suggestions??
