I've got a few issues with Lacey's training. She is a fourteen wk Great Dane, very affectionate and smart. She has been going great with her training, but recently she has started barking defiantly at me instead of doing what I ask. She also still mouthes and is starting to draw blood. She also jumps up and grabs at my clothes, and then she will start barking at me and when I growl her she starts doing zoomies. She is starting to be quite badly behaved and if I don't get some results then Mum and Dad won't let me keep training her and they will do it their way which is basically whacking her for bad behaviour and rubbing her nose in it for toilet training, all that type of stuff. She is good with toilet training apart from one room and she is pretty good with training, she has all the basics down and quite a few tricks and she loves her clicker training. I have just started doing the TOT program with her and she is going well, almost instantly she will look at me and she already sits.
Does anyone have any suggestions?
