That's surprising, usually dog-owners bluntly reject that their dog would do "something like this". But i assume you have it all on video. - Did she also explained how she will prevent her dog from doing what it did again?
It's a husky, so she fully believed he would do it. He also came back that morning coated in mud from chasing the geese around the big mud puddle trying to get them. She says she thinks what happened is that the link on his chain loosened up and that's how he got free.
They had put the huskies out on chains instead of in the yard they used to keep them in because she was letting her dachshunds use the yard - they're small enough to be prey in our area, so they can't be out not in a pen. They had even electrified the top of the pen to keep the huskies in because they know they are escape artists.
She said she's looking into rehoming the dog - she doesn't want it to happen again, and she even flat out said she can't afford for it to happen again. $600 isn't a small amount.
