Ugh I'm wrong -- I'm glad I checked back (work is incredibly busy today and I picked up a wrong line). My vet has just switched to Idexx from Antech and I'm having the devil's own time reading this (my eyes slipped to the wrong line so I was way off) so what I said wasn't accurate.
Idexx's range for WBC is 4.0 - 15/6 as the "General Range" so 3 would have been low but not THAT low. -- and like Jackie I'm assuming it's in the thousands (altho what I said above is Idexx's ranges -- but I know Idexx reports read different than what I'm used to reading for Antech but my vet told me he got fed up with some sloppy work and switched *sigh* so I'll get used to it!)
Just by way of comparison -- Luna's is 5.1, Tink's is 9.8, and Charlie's is 9.2 -- same dogs, same food, none fighting infection but still quite a range.
The WBC fight infection ... so "low" would be ok if there were no infection to fight.
Essentially I wouldn't think white blood cells would have a ton to do with a *small* heart - a smaller heart has to work harder to push the same volume of blood thru. You'd need to watch blood pressure, and such with a smaller heart.
The breathing change can be heart. If the body is having a hard time getting as much oxygen as it wants they will pant to offset that and that would not be unheard of in a small heart.
