Thanks everyone for your input...YT is certainly a wonderful place! I've learned so much from everyone and have had many worries eased from all the expertise available here.
I was concerned, but I guess Topher just hasn't felt the need/desire to master the sound yet...or he finds that his bark gets him what he wants...OR...perhaps hubby is right and he's terribly spoiled and has had no need to whine...lol...!! It's probably a combination of all three.
thanks again!
