Choose your dog's name wisely and be respectful of it. Of course you'll want to pick a name for your new puppy or dog that you love, but for the purposes of training it also helps to consider a short name ending with a strong consonant. This allows you to say his name so that he can always hear it clearly. A strong ending (i.e. Jasper, Jack, Ginger) perks up puppy ears—especially when you place a strong emphasize at the end.
Puppies develop very quickly during their first three months, particularly after their eyes and ears open and they are no longer completely dependent on their mother. Their coordination and strength improve, they spar with their littermates, and begin to explore the world outside the nest. They play wrestling, chase, dominance, and tug-of-war games.
Discourage him from biting or nipping. Instead of scolding him, a great way to put off your mouthy canine is to pretend that you're in great pain when he's biting or nipping you. He'll be so surprised he's likely to stop immediately. If this doesn't work, try trading a chew toy for your hand or pant leg. The swap trick also works when he's into your favorite shoes. He'll prefer a toy or bone anyway. If all else fails, break up the biting behavior, and then just ignore him.
Teach a cue. Introduce your puppy to a sound cue that means, “food is coming.” Some people like to click and treat, some people use a word like “yes,” and some people cluck their tongue. Whichever you use, the method is the same: In a quiet, distraction-free area, with the puppy on a leash and collar, make the sound. The second your puppy turns toward you and/or looks at you, reward him with a treat. After a few repetitions, you’ll notice your puppy not only looking at you, but also coming over to you for the treat.
The Boxer is happy, friendly, intelligent, attentive, and loyal. Boxers develop strong, close bonds with family. They have lots of energy and a serious demeanor, though they can be clownish and playful as well. They like to grab and carry around just about anything they can in their mouths. Boxers tend to get rowdy when the food bowl is empty. They make excellent guardians and companions.
If your pup lunges: If your dog is going after something while on a walk — another dog, a car, a skateboarder, for example, be proactive. Try to redirect his attention with a treat before he has a chance to lunge, and increase the space between your dog and the target. Stay alert and be prepared before the target of his frustration gets too close. This type of behavior may be more common in herding breeds, but any dog can be startled by something he’s not used to or finds exciting.
