We got a bunch of English Setters, but a couple years ago before my wife retired from the county shelter we adopted this dog at about 6 months old. He was probably 5-6 pounds then and now about 10-12 pounds. He took to me right away (well after about a half hour of coaxing) and no one else could touch him as he would bite, probably out of fear. That soon faded. What made him kinda cute in a sympathic kinda way is his overbite. He's got one of those tails that have a 360 degree curl. I can say he has no fear of any size dog, but some little guy's are like that. Christmas morning waiting for others to wake up. Facial close up Any thoughts?
