I've been debating this question myself. My husband and I only have one Sheltie -- Callie -- and my daughter and her husband own Callie's sister, Shelby. I've noticed that Callie is much less demanding when Shelby is over playing, but that's usually only once or twice a month.
On the other hand, Callie is jealous enough when I'm holding one of our two new grandsons that I'm not sure how she'd react to another dog that wanted her Mom's attention. We've frequently had two dogs at a time, but it's mostly been one indoor dog and one outdoor dog.
With both of us working full-time I feel guilty about being gone from Callie as much as we are though. That makes me wonder if adding another one is only unfair to another dog that wouldn't have humans home during the day, or if two of them would mean that they could play together while we were gone.
It's a hard decision to make!

It has made for many challenges and a lot of patience and constant vigilance. I love all my babies to death and would never be without them as they are my life but in hindsight I would not have brought Reno into our home.
Thank you one and all for your responses. They all are helping me to decide.
