surprisingly aggressive behavior for a lab. They usually don't become aggressive unless their defending their loved ones, one of the traits that make them excellent as a family dog.
It is truly sad Larry, I am sorry for your loss. I know to a lot of people, pets are just that pets but to those of us that have been lucky, these "pets" become far more than just pets to us. It's been already 6 years since I lost my mixed breed mutt, Muttley and I still feel the pain from the loss every time I think about her or look at her dog tag on my key chain.
