If your pup barks: Some dogs have the habit of barking at other dogs while on a walk. Oftentimes, this behavior comes as a result of lack of exercise. Make sure your dog gets the proper amount of mental and physical stimulation for his age and breed. If this is still a problem, use the same process as you would if your dog is lunging, as described above — create distance and offer treats before he starts to bark, so every time he sees a dog he gets used to turning his attention to you.
The Boxer gets along especially well with children. They also get along well with other dogs and household pets, but may be aggressive towards unknown dogs. It is best if the Boxer undergoes early socialization due to its strong, boisterous personality. Female Boxers may fight each other on occasion. They are naturally inclined to protect you and your family from strangers.
Once your dog can stay in a sit for several seconds, you can begin adding distance. Place him in a sit and say “stay,” take one step back, then step back to the pup, give a treat, and your release word. Continue building in steps, keeping it easy enough that your dog can stay successful. Practice both facing him and walking away with your back turned (which is more realistic).
Bring your puppy to the crate for naps and quiet-time breaks so that he can “unwind” from family chaos. Start in increments of 10 minutes and work up to longer periods. Offer treats when he goes inside, and distraction toys, like a stuffed KONG. For years, this author has been giving her Yorkie a treat every day as soon as he goes into his crate and sits. Now as an adult dog, he runs to his crate each morning in anticipation of the goodie.
