My Jack Russell is pg and is due at the end of May. I'm going to the vet to find out all the "medical" needs for her pg but what are the other things that I need to know. It will be cold outside, so I can't keep them outside, but what do I keep them in? I'm sure I don't want them running around my house and messing on everything. My girl normally sleeps on my bed so this is not an option for her and her puppies. Also, at what age do they start going outside and playing on the grass etc. I've never had puppies and am totally clueless. Any advice please.
