Your brand new puppy will bring you much joy at home. But with that joy will come frustrations as you train your new pet. Barking and biting can be problems if they are not dealt with correctly. If you learn how to get your new puppy to stop barking and biting at you, both you and your pet will have a much happier relationship.
Keep your dog exercised. Daily walks and playtime are important for your puppy health and happiness and will lead to better behavior and less barking and biting. Play fetch with a ball in your living room. Invite a friend and their dog to meet you at the park to run out some of your puppy's excess energy.
Give him chewy bones or toys to help alleviate the pain of teething. Your puppy is probably experiencing some aching pain as his baby teeth fall out and new adult teeth come in. There are specific bones and toys that can help your puppy during this time. Compressed rawhide and flexible chewing toys work well. You'll want to keep a fully-stocked supply of bones and other toys in order to keep his barking and biting at bay when your puppy is teething.
Take her out for potty breaks every two hours or so. Sometimes a puppy will bark or bite at you because she has to go to the bathroom and she is trying to let you know. Pay close attention to the signs the puppy is trying to give you. When she starts to bark or bite at you, take her outside for a potty break and see if that helps.
Try ice cubes. The cool, crunchiness of ice cubes is very soothing for a puppy that is teething. Some teething toys also are designed to go in the freezer before they go in your puppy's mouth. Try this with rubber toys or even putting yogurt in ice cube trays for a special, soothing treat.
Discipline him when he barks or bites at you so he knows who is in charge. This doesn't mean hitting your dog, but sending him to a "timeout" in his crate or putting him in a holding position to show him who is the leader of your pack.
Make sure the puppy is well-rested. For a 4-month-old puppy, frequent naps are needed. After an hour of playtime, your puppy may be barking or biting at you because she is overtired. Usually, puppies will sleep for two hours in the morning and two hours in the afternoon. Put your puppy in his or her crate for some down time.
