Although a dog can’t speak, we can always judge what it wants to express from its behavior. For example, it sometimes bites the trousers of the dog owner, so why do dogs like to bite the trousers? Why do dogs like to bite pants hems? Next, let’s take a look at what dogs want to express by biting their trouser legs.

1. Consume physical energy

A puppy has a lot of energy. If it does not get enough exercise, it may bite its trouser legs to consume its excessive energy. Therefore, the owner can usually prepare more toys for the dog, and interact more with the dog if he has time. The dog's energy will be consumed and he will not bite his pants.

2. Attract the owner's attention

If the dog bites the owner's trousers and pulls in one direction while biting, it may be because it is too bored, so it wants to attract the owner's attention in this way, or it wants to take the owner to a place. The owner does not need to be too nervous. He can use toys to divert his attention, or take his dog out for a walk.

3. Teeth Changing

Dogs usually start to change their teeth at 2-4 months old. Due to the itching and discomfort of the teeth, they will grind their teeth on their trousers or other things. If the dog is indeed losing teeth, the owner needs to prepare some bite-resistant things for the dog, such as teething sticks, rubber toys, etc., to help the dog grind its teeth and relieve the discomfort of the teeth. At the same time, attention should also be paid to supplementing calcium and nutrients for dogs, so that the teeth that grow in will be strong and not easy to fall off.

4. Practice hunting

When the owner walks, the trouser legs will keep swinging. At this time, the dog will have a strong interest in the trouser legs and regard the trouser legs as prey, so it instinctively wants to hunt and practice its biting skills. In this regard, owners can prepare long, strong and soft toys specifically for interacting with dogs.
