I was having serious barking problems with my dog. We had initially went to the store to get a barking zap collar to stop him. We ended up talking to the dog trainer Becky. She was so helpful and she was able to determine that our dog has anxiety and she gave us so many helpful tips. She had us try the pheromone collar and also had us get our dog a few interactive dog toys to keep him busy while we crate him. We will be trying her 6 week training program as well.
