i have a lazy old rat terrier who has never chased anything in her life, and a year old chihuahua/shihtzu - she was the one that the hens used to chase around the yard. i would give them snacks and she would try to steal some - it was the best entertainment. she's very fluffy so i daydream about seeing her laying on the couch with a brood of chicks under her ears - but then i remember that she chews the hands off barbies... i dont want chickies that close, lol.
