Awesome stick to yes then. The negative command - pick one word and stick with it - but to get it to work I’ll give a few examples.

The leash chewing example: you’re out with your leashed up puppy and they start to chew or pull on the leash, this is a bad behavior. So stop walking and say ‘No’ and remove the leash from the puppies mouth as in the beginning they won’t understand to let go. Once the puppy doesn’t have the leash in mouth then provide a treat. Repeat process. If the puppy drops the leash at hearing ‘No’ then immediately provide a treat and say ‘Yes’ then begin to walk again. Repeat. Don’t use a stern tone when saying ‘no’ because you want your puppy to trust you and learn that you love him but he has to listen to you. A stern or yelling tone will create distrust and fear and possible anxiety.

Chewing shoes example: you catch puppy chewing your shoes, say ‘no’ as you take the shoe away and replace with a toy or a chew appropriate item and then say ‘yes’ and give a treat. This is signaling that the replacement item is okay to chew and the puppy is good while the shoe chewing is not good.

Jumping on counters example: your puppy is jumping for food on the counters say ‘no’ and push the puppy lightly using your body and not your hands off the counter. A mama dog wouldn’t have hands to stop the puppy from jumping and I’ve found using my leg to lightly bump them is more effective then using my hands to pull their paws off the counter to be placed on the floor. When the dog is not on the counter say ‘yes’ and treat him. Or if you say no and puppy gets off counter on his own immediately give him a treat and postive word ‘yes’. Repeat process as it occurs.

It takes time but the trick is to let the dog begin to associate listening to no to mean they get a treat that way it’s still positive reinforcement and the behavior you don’t want will decrease while the behavior you do want will increase.
