Dogs are such little pack animals, so I do think they love having another doggie around. That said, it can take some adjusting on the 1st dog when a 2nd one arrives. Sometimes the 1st dog will feel anxious, needy, and not really want to be around the 2nd dog - this was how Wylie felt (at first) when we got Marcel. When we got Pfeiffer, there was no hesitation at all for any of them.
Btw, Wylie is 7lbs, Marcel is about 3.4lbs, and Pfeiffer is about 3.6 pounds. They all play together so wonderfully! Granted, Wylie is the strongest - but it's never been a problem. Perhaps though, you could find a good breeder and tell them the weight of your kiddo and that you're hoping for a pup who turns out around the same weight? A good breeder can predict a fairly accurate ballpark adult weight.
