Around the house she only needs her collar when she is getting riled up. When the house is hectic I will have her wear her pinch collar with a short "training tab" (think like a 8" leash) so that I can grab it, correct her, and let her go again without her tripping on her leash the entire time. But when the house is calm she hasn't needed much correcting inside.
Her commands are going really well. She still needs occasional corrections for Down and sometimes for Implied Stay if she gets distracted but she is easy to correct and she loves praise so she isn't a difficult dog to set back to task. She loves praise so much that I have to keep her praise very warm and calm or else she throws herself a little celebration for getting the answer right.
We are in proofing stage now and so we are working around distractions and for longer periods trying to get her as experienced as possible before she goes home this weekend.
