I had three!(Just look at my avatar!) I do know it is my limit. My oldest had allergies and it was a full time job just keeping on top of those! All three were on different foods at one time too, which made feeding time more of an orchestration!
In the end I wouldn't have changed anything! There were times all three were running and chasing each other thru the house and all you could do was get out of the way and watch them go! (With a huge smile on your face!) I will say if you take you dogs with you often, if you don't have a SUV, get one! Three boxers in one backseat gets tight! Plus one doesn't get a window, how unfair is that?
Is it crazy? Absolutley! Is it worth it? Absolutely! Please post pics soon!
