My name is Coco!

Coco is a 3 year old beagle mix who has been great with our kids, and they love him. He needs a home where he could be an indoor dog with a fenced in yard. We live in the country and he runs within an invisible fence. About a year ago he started barking aggressively at the Amazon drivers who seemed to be increasingly racing up to the house blaring music. He then started becoming aggressive with all cars pulling up. If I or one of my sons held his collar he would excitedly sniff people and jump for attention, but he would stop all aggression when I introduced him. About a month ago a friend arrived unexpectedly and Coco raced around the house and bit her before anyone was able to stop him. Since then he stays in the house or garage, but we do not have fences on our property and we fear him being out to pee when someone arrives even though we're watching diligently. He is sad spending so much time in the garage and needs a family that wants an indoor dog.
