How do you tell a puppy no?

1. Use a firm voice. When you tell your puppy no, you need to use a voice that is firm and authoritative. This will help your puppy understand that you are serious and that you mean business.

2. Be consistent. You need to be consistent with your no commands. If you sometimes let your puppy do something and sometimes you don't, they will get confused and won't know what is expected of them.

3. Redirect your puppy's attention. When you tell your puppy no, you should also redirect their attention to something else that is acceptable. This could be a toy, a treat, or another activity. This will help your puppy learn what they should do instead of what they are not supposed to do.

4. Praise your puppy when they obey. When your puppy obeys your no command, you should praise them immediately. This will help your puppy learn that they are doing the right thing and will encourage them to obey you in the future.

5. Be patient. Training a puppy takes time and patience. Don't get discouraged if your puppy doesn't learn right away. Just keep being consistent and positive, and eventually, your puppy will learn what you want them to do.
