There’s a great article at PupBox on when to tackle different skills when training a puppy that I found very helpful. They also sent me this graphic with some helpful tips about using treats during training.
I have definitely found that I have to switch things up when training Baxter. I can use low value treats or even dog food when training at home, but for puppy class, I need high value treats that are only available during that time.
So different from my cat, who just gets treats once a day, at bedtime, and prefers the same ones all the time. If I give him a different treat, he will usually throw them up!
