(Said in a NY accent per DH)
Three is nuthin' honeyyy! LOL..Seriously, it's not a whole lot more work unless you get a little one with a ton of attitude. Then it's like dealing with 20...LOL.
I bought a little boy Chi a while back that was gorgeous! From show lines and so so pretty. WHAT A BEAST!
He completely disrupted the household with all his dominance posturing and guarding of food, beds and toys. Pretty soon I was keeping him seperate to prevent my most shy rescue from being intimidated. After about a month, and the only change was not for the better, I decided to rehome him. He's now absolutely enthralled with being the only dog in a household...he's king...and he's very well behaved with that status.
I have four now, and they are extremely compatable. Everyone eats on schedule and potty-s on schedule. They all play well together and I can leave them all together in their playroom with no altercations.
It really is no more work, provided your 'pack' is in harmony.
Just my thoughts...
