Dogs that are usually so well-behaved and obedient can be extremely aggressive towards their owners at certain times and show their teeth as if they want to bite. This is undoubtedly sad for owners who have taken good care of their dogs for many years.

What are the reasons why dogs show their teeth at their owners?

1. Protect food.

For dogs, eating and drinking enough is the most important thing. If you approach it while it is eating, it will think you are trying to steal its food and will grin at you to warn you.

2. Protect your “properties”.

The dog treats the toys, kennels, and teething sticks you prepare for it as its own personal dog items.

A possessive dog will not allow other furry children to get close to his belongings, not even his owner.

3. Jealousy.

When you bring a new "family member" home, you are so friendly to the new member that you ignore its existence.

The dog will start to get jealous and grin to make you notice its presence.

4. Protect children.

After a female dog gives birth to a baby, she may be aggressive towards her owner when she comes near.

Dogs are very protective of their children and do not allow anyone to harm them.

Owners should remember to play with their dogs more to enhance mutual affection.
