Wow iam asumming that you have corrected this problem since you havent posted any more incidents.Iam never in favor of baiting a dog to get it to obey a command that it previous refused.Obvious your dog felt her place slipping in the chain. your brother in law correctly lead your dog by collar but that should of been your job.not harsh but in control,the treat might come after its in the crate but never to convince it to go.i like tuff dogs as the owner of a very alpha Fila i dont allow him to disobey my command , because i know he is testing me,and i dont really baby him i know he bites an i handle him as such.I dont ask him to do anything i tell him..do some reading pack leaders dont ask they demand ,disrespect is an animals way of getting back or moving up the chain.
