We also have a possible Basenji/Terrier (Yorkie) mix. I've had some doubts, but seeing this picture of Rosie, I can't help but see my Rebel. Such a great looking dog, and if she's anything like our girl, you're in for a treat!
What a cute little guy! I find 2 is easier than 1, they entertain each other, but when one gets into mischief so does the other lol. I found house training much easier with the second one as our boy taught his little sister and also tattled on her when she did have an accident ( he would come and get me and take me right to it lol), ours are a year apart and it works great
