How do you get a toy poodle to stop barking at people in the house?

Poodles can be rather vocal dogs. The first thing to do is to teach your dog to speak on command. Once they learn the "Speak" command, you can teach then the "Quiet" command.

Be persistent and consistent. Have regular training sessions rather than waiting until you are dealing with visitors AND a barking dog. Praise your dog for being quiet in any situation where they would normally be barking, saying "Good Quiet".

You can also try walking away and ignoring them when they bark - your reaction may actually be encouraging the noise inadvertently. And make sure visitors do the same.

Another (Safe) Alternative to Prevent Your Dog From Barking

A dog parent can also try safe ultrasonic bark control. When your dog barks the ultrasonic bark control unit emits a high frequency sound that only your dog can hear. Each dog bark triggers the bark control unit to emit the sound. The dog will stop barking when he/she hears it. Soon the dog will realize that their barking causes the uncomfortable noise and will stop barking. The ultrasonic bark control is not recommended in a house with cats since they are also able to hear the high frequency sound.

There are two types of Safe Ultrasonic Bark Controls: Indoor and Outdoor. The Indoor Bark Control unit sits on any flat surface in your house. The Outdoor Bark Control looks like a Birdhouse and can be placed on any outside tree. The device not only looks great for your outdoor decor but an added benefit is controls not only your dog from barking but also your neighbor's barking dog. The Indoor Bark Control unit can be controlled manually or automatically. Manually means you will press the button when you hear your dog bark. Automatic means the device will emit the sound when it picks up the dog bark. The product is manufactured by a reputable company called Petsafe.
