Evaluate the dog's needs as much as your own wants/needs. Some dogs flourish with a packmate, some dogs do better alone.
I ended up with a young female just months after adopting Cable. Some days it's fine and dandy, other days I wish it was just Cable. The circumstances were such that it was for the betterment of the female(Allie) and returning her is not an option. Cable can go either way, he's stable and pretty hard, BUT I really do think he'd really shine as an only dog. Allie loves her big brother and they play awesome, just sometimes I can see the frustration Cable endures when he wants some human/dog quality time.
