So the other day our three year old was playing with our dog, 5yo min dachshund/brussles griffin thing, the dog ran in front of her and tripped her she fell on the dog who then bit her across her chin/ upper throat. She's never done this before always good with people, did snap at her a few days before this. Any ideas why it happened? The dogs always running under her feet its how the have played for almost a year now just chasing each other. Really don't want to get rid of the dog, our kid was upset more for the wife yelling at the dog than getting bit. She said "don't yell at her she's only little". Lol
