I have a 2-year-old Doberman who is usually well-behaved, but recently she has been chewing on things that she shouldn't be. I've tried redirecting her attention, but it doesn't seem to be working. I'm at my wit's end and I'm considering punishment as a last resort.
I don't want to physically harm my dog or do anything that could be considered cruel, but I do want her to understand that her behavior is unacceptable. Can anyone give me suggestions on how to punish a Doberman in a humane and effective way?
Thanks in advance.
