I've been reading the forum for hours now - lots of great advice. Our new dog, Barley, is a 14 week chow mix. We've had him 6 days now, and are working through typical puppy stuff - dominance, housebreaking, etc. but have a concern about our other dog, a chihuahua/whippet, which I'll post in another forum. Anyway, so glad I found this site!
