I might be too old already to get another dog because I don't want another one as long as I have the two Chihuahuas. Two is my new number....my limit. Of course, two really isn't two. It's three. I also have Tokie, my son's dog....at least for now...probably for a year or so until he finds a suitable living situation for a dog and for him. But, if I ever get another dog, I see myself with another Chihuahua or two or a Poodle. I've always been enthralled with Poodles. A standard Poodle really attracts my attention. However, small dogs might be the wiser choice, so a miniature might be best. There are so many attributes to little dogs.
There are indeed many cool breeds and of course, Dobermans will always hold a special place in my heart. But the way my life style these days has been evolving, I probably couldn't give a Dobe all he should have.
