How sad for your friend Bonnie.
I'm sure that the breeder will help you pick the right pup to get along the best with Chipper (although it's not 100% certain that they'll NEVER disagree). And with all the members here who (are lucky enough to) have multiple corgis, I'm sure you'll get lots of good advice on how to prevent common problems (such as Muddy's collar issue above).
And you already have a pretty peaceful multi-dog household, so you must be doing something right! Trust yourself!
