I have a 9 year old yellow lab, the sweetest dog you could find. I would have bet she would never have bit anyone, least of all me. Today I was proven wrong. She had been outside, and was chastised for not getting the paper. She went in her crate, and then left the crate and went into the laundry room. This is where she goes when she is scared or upset, as when too many people are around or there is thunder. I tried to get her out of laundry room, she began to growl and snap a little. At this point I felt is was a battle of wills, and I did not want her exhibiting behavior like this. She has never acted like this before. I reached for her collar and she bit me fairly hard, there are five punture wounds and the hand is swelling.
She has never been mistreated in any way.
I feel that if she bit me I can no longer leave her with others when we need to, and I am fearful of her being around my 15 month old niece.
What I am looking for is some explanation of why she would do this?
