melanie, I'm an area rep for Dogs Deserve Better if you can tell me what city and state your in I can contact a local rep from that area and have them talk to the owners.
If that doesn't work then DDB tries to get the owners to surrender the dog over to us DDB.
We also work w/animal control. Alot of times animal control will say they don't have the time. We don't back down until the dog is either back in the house and a family pet again or the dog is surrender to us.
Either way we can try and take care of this. We will send them out a letter first then do a follow up and if the dog is still outside that's when we will go and talk to the owner.
We have alot of success stories.
Please let me know.
