Do all dogs bite their owners?

No, most dogs do not bite their owners.

Some dogs playfully mouth their owners but even this should be discouraged.

A dog that bites its owner sees itself as an equal. Biting and even playful mouthing are signs of aggression.

In this case the owner should exert their authority and make the dog respect them as alpha. Every time the dog bites or mouths hold its mouth closed with your hand and with a firm authoritative voice say “no!”

Other things to make a dog recognize you as alpha is not letting them get on beds or furniture (keep them below you). When giving treats always make them earn them by sitting, shaking hands, or other tricks. If you make them earn their treats they will view you as master; if they get treats for nothing they will see themselves as master.

Believe it or not I had to go to a dog psychologist for my dog’s behavior. Even though he was house trained and has a doggy door he sometimes peed on our carpets and he also sometimes snapped at or mouthed us and visiting kids. The psychologist explained that our dog saw itself as one of the adults and leaders of his pack (our family). When we lowered his rank in the pack his behavior instantly improved.
