Puppy day cares won't take a dog that isn't comfortable around other dogs. Try taking your dog to a nearby off-leash dog park for an hour over the weekends to get her accustomed to being around other dogs and people. Maybe start out for 15 minutes to see how she behaves, then up it to 30 minutes, then eventually an hour or more if she shows signs of having fun.
A little dog-play is normal, but just be prepared to intervene if your dog isn't acting appropriately at first. Other dog owners will be understanding at first if you show an effort to keep your dog behaved and you explain that you're trying to socialize your dog. If your dog can't or won't socialize, you will eventually be asked to leave.

Did a double-take when I read Ordnance training.
Maybe I need glasses?
