I wouldn't be breeding if I were still working. I started breeding to keep me busy because I don't work anymore.
I can't see being away from mom and pups to work a full time job. It would be kind of "messy" if nothing else went wrong... by the time you got home.
Also, at some point the pups have to be fed at least 3 times a day when they are weaned from mom.
I have three litters now... and two litters are over 4 weeks old... it's getting crazy around here!! Cleaning up poop and pee and putting the pee pads back in place... plus feeding them mushed up puppy food.
Hopefully you have friends and family who can help you out. Best of luck to you.
