We have had our rescued beagle for almost 3 mths now, he is very slowly begining to trust my husband. When we go off leash he plays with him and bays at him as well. All is great until we return home and then our boy begins growling and cowering. He is not quite a year old and I am very certain he is a puppy mill product. I need suggestions, because he is the most amazing dog with our children. And I have fallan for this fur baby as well!!!
