Dog trainers must be able to do these things

One very important thing that I forgot to mention. There will be times that all three scenarios when using food or play will fail and the dog will have no interest whatsoever. Not a problem not a big deal sometimes in the end it can actually benefit you. Focus on the leash, Work, the negative reinforcement, implementing and teaching the basics by rewarding with freedom and running around. That will get you very far even when all the motivational stuff fails because in reality that leash work, that negative reinforcement, is very motivational. https://www.pakmasters.com
