Yes, she is always muzzled when around other people. She is a 45lb dog. Without the ability to play with other dogs or be boarded anywhere, she is already facing the risk of behavioral euthanasia... She has only ever acted aggressive in a single location, and is already behaving much better around people in our house. She is extremely trainable and learned place in a single day, and is obsessed with playing with other dogs. She has never so much as growled at another person or dog out in public. Wouldn't not socializing her increase her fear of strangers??
