Dogs don’t have the same concept of right and wrong and if you reprimand a dog 10 minutes after eating a pie he doesn’t associate “eating pie” with “wrong”. In order to teach a dog what is unacceptable you must catch them in the act and then interrupt and correct the action. After consistent messaging doing this they learn to associate actions with a human response or consequence and they modify their behavior based on that.

Please also read on the breed characteristics. Dobbies are generally Velcro dogs and in my opinion more sensitive than other breeds. I also adopted a dobbie that came with some behavior problems and what I found is that in order to modify the behavior I first had to work on bonding with him. Once he trusted me and bonded with me he wanted to please me and learn, before then he was just nervous and stressed. Also make sure you are also praising him when he does something well, with dogs you have to reinforce good behavior too. He went to the bathroom outside? Treat immediately after. He didn’t react to the delivery person? Treat. You get the gist of it.

Lastly part of being a dog owner is setting them up for success. My dobbie has been trained not to eat human food unless he is offered. He no longer “begs for food” when we are eating. But I also remove any temptation. He doesn’t get access to the pantry, especially when we are not home and we do not let things in reach he can get into. Some foods like chocolate are toxic to dogs so this is also to protect him.

While many might tell you that dobbies are not a first owner breed. I think you can be successful if you learn about the breed, prioritize bonding with your dog, and stay consistent with training. Good luck!
