Most puppy mouthing is normal behavior. However, some puppies bite out of fear or frustration, and this type of biting can signal problems with future aggression. Puppies sometimes have temper tantrums. Usually tantrums happen when you're making a puppy do something he doesn't like.
Puppies can often get overstimulated which causes them to get into a biting frenzy, or just like a toddler that throws a tantrum when it's time for a nap, your puppy may be showing you that they need crate/playpen time to unwind and relax. Puppies also may bite in order to get OUR ATTENTION!
If your puppy becomes aggressive about biting or if the bite breaks the skin or causes bleeding, it's a sign the dog is trying to be dominant. You must immediately take action when a puppy won't stop biting and can't be distracted by treats or commands.
Don't use physical punishment
If you do not want your dog to bite, punishing them for biting is not the way to make it stop. Punishment can only provoke fear, anxiety, and aggression.
The instant you feel your puppy's teeth touch you, give a high-pitched yelp. Then immediately walk away from him. Ignore him for 30 to 60 seconds. If your puppy follows you or continues to bite and nip at you, leave the room for 30 to 60 seconds.
In one posture, hold the pup over your head, firmly supporting him with both hands and stare into his eyes (staring is a dominant behavior to the dog). Maintain this position until the pup has been still for 10 seconds. He must be still for that length of time or he hasn't submitted to you.
Like territorial behavior, protective aggression usually appears as puppies mature into an adolescence or adulthood, at one to three years of age. Many dogs show the tendency to guard their possessions from others, whether they need to or not.
Do Puppies Get Aggressive During Teething? Some people may confuse some growling, biting, or tugging as aggressive behavior in a puppy. The truth is that the puppy is probably showing excitement at playing or trying to relieve dental pain.
Is Your Puppy's Nipping a Sign of Aggression? A snappy puppy may be worrisome, especially when paired with growling and barking. In most cases, nipping, growling, lunging, and barking are all part of your puppy's play behavior. It is rare for young puppies to be exhibiting truly aggressive behavior.
Give your puppy an alternative item to chew
If they start nibbling at your fingers or toes while you're playing, offer a toy instead. Again, if they continue to nip, stop the play session immediately. If you've been training your puppy to sit, you might also redirect them by asking them to sit and rewarding with a toy.
The “Witching Hour”
Many owners find that 7 a.m. and 7 p.m. bring out the worst in their puppies! If you know that a particular time of day prompts crazy biting, do your best to manage/prevent the behaviour and engage your puppy otherwise.
The most important thing to remember is that for the vast majority of puppies, mouthing or play biting is a phase that they will typically grow out of once they reach between three and five months of age.
There is no way to sugar coat the fact that puppies are crazy. They can be down-right nuts! And puppies are especially crazy during the Witching Hours: roughly between 5-8pm every night. It's 100% normal and common.
Undesirable behaviours such as barking, chewing, counter surfing, house-soiling and jumping up commonly begin to occur at around 3-6 months of age. Your puppy will not grow out of these behaviours. On the contrary, it is more likely that these behaviours will worsen if not addressed early on.
For a dog who is acting out of fear or frustration (for example, a dog who is barking and lunging on leash), using the word 'no' to stop the behavior without helping to alleviate their fear or frustration will often lead to an escalation in behavior, such as growling, air snapping, or biting.
Most puppies start to calm down as they approach their maturity age, which is usually around 12 months, but for larger breeds it can be more likely to occur between 18 months and 2 years.
The act of holding a dog down forcibly as a correction is generally called the "dominance down." It is inappropriate, ethologically absurd, and completely counterproductive when interacting with dogs.
Contemporary experts urge against all uses of physical discipline. Tapping or bopping a dog on the nose can be misconstrued as playful behavior, and being too rough with your dog can actually trigger biting, reactive, or defensive behavior.
