congrats !!Now help for you and the little woman. After raising two young lady rotties myself, I did the following.
Buy two or more pairs of woman's sized tights. Leggs brand XL woman worked the best for us cause we had some big girls. You can also use old panty hose if you have some.
Cut the legs off almost all the way up.
Use a self stick pad(thin super maxi pad) (Always) was good ,no wings.
Place pad in area that will cover as much as possible.
Have her step into the tights and pull all the way up past her belly.
If she has a tail, make a slit and pull tail through. If she has a nub, make smaller hole and just pull around nub.
This will keep everything in place and she won't be able to chew the pad. Everything comes off to pee and poop. You can just reach in and change the pads.
Hope this will help you.
As far as the upset stomach, it's very possible she had diarrhea from being in heat but, I'm not a vet. Lola went into heat a 6 months and started licking and cleaning herself. She too got diarrhea but she was better when she was padded up. In any event, she was spayed before her next cycle.
