I recently got an ACD, about 5 months old. She is doing well and I’ve started training her. During training sessions (when treats are around) she does very well and usually at other times as well. But there are times when she simply ignores me and any commands I give; kinda like “who are you and why are you speaking to me? I’m retired and work with her a couple of hours a day but she is an outside dog (wife agreed to a dog but not inside). Like I’ve said, most of the time she is great, wants to be with me, trains easily, affectionate. Then, like the flip of a light switch, I don’t warrant her notice. Any ideas?
