Almost every time I give Ditto a command, she barks. She usually does what I ask her to also. If I tell her to sit, she barks as she is doing it. Its annoying. I always say no, and tell her the command again, and never give her the treat when she barks along with the command. However, this has been going on for about a year. The only thing that works is if i say "ah ah" when I can tell she is about to do it. I guess its not a huge deal, it just gets really annoying, especially if we are outside ( I dont want to bother the neighbors.) Any thoughts on why she does this ( other than she is excited) and how I can stop it?
