I'm gonna say 'no.'
I guess alot depends on what you want your breeding program to be, how much help you have from family and friends, how flexible your job is. But basically, no...especially if you have 3 expecting females.
It takes alot of time away from work, so you've have to have a very understanding employer. And that is just for the standard stuff, not even getting into emergencies. I had a full time job, 1 breeding female, lots of help from family. I won't say it was impossible, but I didn't feel like I was able to devote as much time as I wanted/needed to have my program where I want it to be. Obviously, I put the dogs first, but then that didn't seem fair to the company I'd committed to either.
And that was with ONE female...and before you even add in the factor of having a child, family etc.
Now, I have a part time job, am able to set my own schedule and do alot of it from home.
It's still a new arrangement, but working out nicely so far. So I'm working towards advacing my breeding program in the very near future now that I can devote more time to it.
So it's not impossible, but very hard to do, IMO.
