No way do big dogs scare me....considering we have 2 Danes and some various assorted and asundry other large breeds...along with 16 pound Jessie who rules the roost!! hehehehe. You're more likely to be bitten by a small dog than a large dog anyway...Cocker Spaniels are the number one dog for biting and they're little. Anyway...my philosophy is: The bigger the better.
