The smallest size dogs we've had are our puppies now - they are about 4 1/2 lbs. They will likely get just a little bigger. Our sweet 17 yr. old was almost 6 lbs. and lived a long healthy life. I think I'd be more concerned w/ the breeder and health history of their dogs vs. just size. I can say you have to be more careful as the little ones can get stepped on easier, when underfoot.
My biggest adjustment is the vet bills. Double the exam fee, double the vaccines, etc. Also, double the food.
But, the upside is double the fun! My only regret when I got our first dog was that we could only afford one. We absolutely love having two pups. I don't worry about them when we leave them here together. They are actually quite protective of each other and great playmates. We adore them and they truly complete our family.
Good luck!
