I went through this, almost lost my girl.
I have 2 chihuahuas, long hair and a short. We have a big back yard, and we tie our dogs out so they aren't in anyone else's yard and let them out the back patio doors. Neighbors have a pit-cross, and it came over and mangled my long haired. He had her in his mouth and shook her so hard until my dad heard and came out. We had an old wooden chair outside (my mom re-dos antiques) and my dad broke it over the dogs head and he dropped Roxanne. The bill was about 800, we almost lost her. My mom said they wouldn't have to pay the vet bills if they just got rid of the dog, they have A BABY IN THE HOUSE!!!!......they paid the bills and the dog remains there....

I guess they won't get it until the baby is scarred for life?

Hope your dog is doing ok! Best wishes for a speedy recovery The scars heal nicely, roxanne just has a couple bumps, hopefully your little one heals just as nice:)
Going through this sucks. I live in fear of it everyday letting my dogs out now...knowing that dog is still right next door. It shouldn't be like this....
