fostering is so rewarding, i really commend you for wanting to go ahead and open up your home to a great new face every few weeks. I do short-term foster, which is in many ways incredibly tiresome and in other ways a lot more rewarding (nothing like a week-long break after a week of complete mayhem!).
be careful about being the 'fallback foster'. i was picking up a pair of foster puppies and ended up taking home both those pups and a mom and 7 of her 6-day-old puppies. *headache* not only did mom have diarrhea, heartworm, and wasn't eating, but the puppies had to be bottlefed as well. and i do work part-time. but when i saw her face and heard those yelps i couldn't say no, she just couldn't go back on an 8 hour drive to a cold cage.
So know your limitations and stick with them, that's my big problem. also... if you plan to foster dog after dog, instead of a one-off deal, it would be really great to devote a waste-proof room to the cause. puppies dont often come in housetrained and lemmie tell you... getting loose stools out of carpet is NOT something you want to be a daily activity.
i say go for it! fostering is the best thing I've ever done. I've only fallen in love once, and that's hopefully ending in a successful adoption in about 8 weeks.
