Just like when children play with you, dogs also love to play, and while playing, they may put your arm in their mouth. Do you ever wonder why they do this?

Why Does My Dog Put My Arm in His Mouth?
While you sometimes feel irritated or don’t understand your dog’s feelings when he puts your arm in his mouth, it is important to know the reasons for such behavior.
Let us discuss some of them:
# Mouthing
Mouthing is a common dog behavior seen in every dog breed. It is very different from biting. The dog’s first tool to explore the world is its mouth. Similar to infants, they like to put everything in their mouths to explore stuff. Have you seen them chewing their toys or your socks and sofas? Dogs learn to explore the world with their mouth.
So when they are putting your arm in their mouth, they might just be trying to connect with you, understand you, take in your smell and memorize it.
When you are curious about this behavior, the very first answer is mouthing; your puppy or dog is telling you that they want to play with you, love you or want your attention. Mouthing is a sign of affection, do not consider it aggression.
There could be various types of mouthing; let us explore them below:
# Teething
The ASPCA says that mouthing is more prevalent among young dogs. 80% of dogs are below two years old. But experts are not sure that teething is the reason why your dog takes your arm into his mouth.
But still, it is quite a good explanation that puppies in their teething stage tend to eat your hand to relieve the teeth irritation. By taking your hands on the mouth, they may feel better as they soothe teeth gums.

# Playing
Mouthing is the first step for your dog to learn how to play. If they don’t learn at a younger age than while playing, they should not bite littermates; then your dog may end up playing with their mouth and teeth, which could be harmful.
# Greeting
Another possibility why your dog takes your hand in his mouth is greeting. Usually, when a pet parent comes home after a long day or few weeks, your dog is happy to see you again and welcomes you. This is a lovely motive behind putting your arms into its mouth.
# Shows Affection
Maybe by his mouth, the dog seeks attention and wants your affection. A pup may try to hold your hand by his mouth to get your attention while you are trying to focus on something else.
# Extra Energy
As we said before, your dog needs to do regular exercise; if they don’t, your pup uses his excess energy by taking your harm into his mouth out of desperation of activities.
# Boredom
Why does my dog bite my wrist? It is because they are either bored or want to indulge themselves in some activity. This is more likely when a dog does not exercise enough or do regular activities.
So, in that case, dogs usually think that biting your wrist is they are doing regular exercise. To stop this habit, it is important to get the daily amount of exercise as per the age and breed of the dog.
# Dominance
Some people have concluded that dogs take your arms in their mouth because they are trying to dominate you. It usually happens due to Bullying behavior, which is more likely to occur in aggression.

How Can I Stop My Dog From Mouthing?

According to research on mouthing habits, pet owners must react to the mouthing habit through training instead of scolding or trying to turn the dog away.

What is Bite Inhibition?
Bite Inhibition is training your dog to stop mouthing. Dogs who don’t learn bite inhibition don’t understand how soft and easily punctured human skin can be, even when playing.
When pups live with a litter, they understand bite inhibition while playing with other dogs. When pups in a litter play, they love to tease each other with their mouths. When one pup bites the other, that one yelps, and this way, the dog learns how to control their biting habit.

If the dog bites too hard, it could stop them from playing, which nobody wants. However, when a puppy is weaned away from its litter too early, it doesn’t get a chance to understand these important life lessons.
Bite inhibition is an important lesson that one dog should learn to remain calm with peers and humans at a young age. Humans can sometimes take a leaf out of pups’ book when training their dog not to bite they can imitate crying or being hurt to show the pup that the bite hurts (even though puppy bites seldom hurt).
How to Teach Bite Inhibition?
- Do not stop your dog from taking your hand in his mouth.
- Continue playing with your dog until he bites you harder.
- If your dog bites you hard, immediately stop playing by removing your hand from your dog’s mouth.
- Get a toy or chew bone as a substitute for your hand
- When your dog takes your hand in his mouth, distract him by offering snacks from another hand. This way, you can prevent mouthing.
- Indulge your dog into various playtime sessions to keep him busy and make him less interested in mouthing.
