Yes! I did that as well, I went with an opposite sex. Now I have a whole family pack. Hahaha!
I am a very busy person and even though 2 hours a day (for playing; minus the feeding and cleaning) is alot for me, for them, it is just not enough. There is something that a “dog-pack companionship” can do that I just can’t fill.
Now I don’t feel guilty at all even in cases where if I can’t play with them at all. They can keep each other entertained now.
