Yes, that is an English Setter - more specifically a Llewellin Setter. Some say LLewellin is a separate breed from English setter, some say same breed just different lines.
That was our old boy Pistol Pete (named by previous owner after the U-Wyoming mascot). We lost him this fall - he was almost 14 years old - I think, 13 or 14. he was such a sweetheart and my clown dog, I miss him alot. Personality coming out of his fuzzy ears, lol.
He was a beautiful dog, sorry for your loss.
