I had a thought earlier about this topic.
Candy, I think you should do whatever you can to get that puppy back in case the family decides to make it a 100% outside dog or worse take him to a shelter.
Altho I don't agree about the aggressive golden retriever. Bottom line is that dog is not in a good situation and in order for him to reach his potentional as a golden retriever he needs removed from the household. I don't think any amount of working with them will do any good b/c they simply and sadly don't care.
