Why They Bite
It is not at all pleasant when you are bitten by your dog. However, it can mean playfulness and affection! Dogs bite one another when they play together. It is not considered aggressive, and this behavior carries over to the way they act towards you. Make sure to look out for signs of fear or aggression, however.
Sleeping Beside You
Do not be offended if your furry friend likes to skip the dog bed and lay down beside you. They got it from their ancestors! Their forebears hunted in packs and slept together for security and warmth. Your dog only wants to get close to you. Take it as a compliment that they trust you enough to even do this.
