You can put a target plate out and see what he does naturally, but I wouldn't train with nebulous criteria. I think it's a lot easier to train if you know exactly what you want, all the time.
Very true. It's not like he's not bright enough to learn to differentiate.
Can you try and get a private with her so she can see where you are at?If you take all the advice on here and try it all you will screw up your dog.I f you dont know how to teach what the advice may be you will make matters worse for your dog.This is JMO and not everyone will agree.
I can't do a private session with her right now. I had to rearrange things just to be able to take the class in the first place. I can read up on various techniques and ask the instructor to talk them over with me and reassess at the end of the class (while avoiding contacts for the moment). There are only 4 dogs in the class now, so we have 1 on 1 time. That should give me time to research. Guess that's the best I can do for now!
