Barqs, our Cairn Terrier, has done great with the past two guest dogs we have had. They were her size, and males.
Today, and for the next 13 days, we have Angel. Oh GOD! I love this dog. I've always wanted a huge, cuddly dog. She is _75_ pounds (versus Pepper's 11 and Barq's 13)!!! Barqs still hasn't stopped bowing up to her. I think she feels threatened by Angel's size, even though Angel would gladly roll over and let Barqs do whatever she wants. This is the most laid back, snuggly dog I have ever seen. If you stop petting her, she plants one of those huge paws on you. They are bigger than my kids' hands.
It's going to be an interesting 2 weeks.
(BTW - Pepper likes her. Pepper likes everybody and everything. I don't even bother to leash her anymore when we bring in a new dog.)
