if they like their dogs laid back, we have on in bmore who would probably fit the bill.
her name is erin (named afer me by the rescue who took her because i brought her to their attention!) and she's about 4 or 5 years old. she's a portly gal and could stand to lose a little weight, but she's pretty small--about knee-high, about the size of your average stafford . . . she's lovely, loves allllllll people, wiggles and begs for attention, and she tolerates dogs just fine. she very much prefers the company of humans to dogs, but she will sit quietly and calmly when other dogs are around and greets them nicely if they are polite to her. she's living at a boarding and doggie day care facilty right now and she's doing great.
she's a gem. a really great dog.
her petfinder page is here, and she's definitely worth considering. even though the pictures suck--she's much cuter in person!
