Congratulations on your successes so far!!
Personally, I would teach her either the pads or outside. Don't teach one and then switch mid stream - its too confusing - JMO. Bailey started going outside at 10 weeks - we have a private back yard.
Playtime in the family room -yay. Now make it potty training/play time. Potty training is about letting them have accidents and then correcting their behavior. So, let 'er go! Ha, that said - lay down some blankets in the family room so you can save the carpet and wash out the odor after the accidents.
When you go back to work - your baby will probably have accidents and chew the pee pads, etc. Keep her area confined (ours was a 4x4 expen)Expect a mess when you get home - but no worries, just take 5 minutes, get some pet spray and clean it up. (a shop vac near by is a plus!) In time, your baby will stop chewing up the pads and will learn to hold it as dogs naturally don't like to soil where they live. Bailey started holding it all day at about 8 mos.
Bailey ate her poop when I fed her commercial dog food. Now she's on a homemade raw diet and its no longer a problem. I don't know if that's the answer for you - but it works for us.
Housetraining for Dummies - excellent resource!!
Good luck!
