Oh wow... is that so sad.... and I want to send your grandaughter a hug....that's so awful to hear and must have been super awful to see...
I don't understand how people can let a Pitt Bull run around in the first place.....The people are the ones I hold responsible not the dog - I hope they get slapped with more than a tap on the wrist - this happens far too often and it just shouldn't !!
I was so close to my cat at her age too....What a hard thing to go thru at 16...poor Spooky. I hope it was so sudden he felt no fear...bless his heart.
