Hello Cam and Harry! Terriers are little balls of energy, and unfortunately, barking frequently comes from pent-up energy. Here are a few tips to hopefully soothe relations between your dog and the police dog:

• Get your pup into clicker training. You can train your dog to essentially ignore other dogs in this fashion, and reward them for their success with however they like to be rewarded (pets, treats, whatever they'd like!). A good way to practice is thus - buy a dog clicker - they're found it just about any pet shop, Amazon, and they're quite cheap. Think of a task that you want your dog to be able to achieve, like sitting. You click whenever the dog sits, reward it, and eventually, add a vocal or physical cue.

One you have established a few cues with your pup, you can start to work on having it behave the way you want around other dogs. If you have a friend with a dog, you can introduce the two, but have your dog sit so that it doesn't bark or lunge at the new dog. Click and reward when it does what you want, but start with small goals! Over time, you can get your dog to essentially ignore the other dog, as it will expect a reward for its good behavior.

Good luck!
