She is getting pretty good at going through doorways without putting the brakes on. She sometimes still needs a quick buzz from her collar (just a vibration) to light a fire under her pants if she is being stubborn but most of the time she goes through without any issue at all.
She still wears her muzzle around the kids but she is tolerating them better every day. She no longer needs a leash to be around them and she was okay with my one year old daughter gleefully running around with a spatula. She has not barked or growled at them since the first day but she would rather they not pet her (she moves away from them). I think she would probably still snap at them if they pushed her but she tolerates them being around her without too much anxiety.
Tomorrow we are taking her go-home video and continuing work on her obedience. She is making good progress.
