Ok, then scratch basenji. Maybe pharoh hound too because of the coloring. Well in my opinion I would narrow it down to: German Shepherd, Beagle, and Smooth Coated CollieHe barks when he's around other dogs, and howls when he hears fire trucks. But doesn't bark when I play outside with him. I've never seen him chase a small animal, but he does love to be around other dogs. He'll half fetch, only comes back 50% of the time. Always loves to play in the grass, get belly rubs, and play tug of war.
