If you’re willing to do some work and are determined to train him, start by keeping him on a leash tied to your belt all the time. Teach him to sit and stay – at first when it’s quiet, then add distractions. Make him sit before he gets fed or petted. Take control.

If the doorbell rings, he should be allowed to bark for about fifteen seconds or as long as it takes you to get to the door. Pick a new command – a word that he’s not already immune to – like STOP! or ENOUGH! Every single bark after that command must be corrected.

Don’t hold him in your arms – that makes him feel like you’ve got his back and you approve. Put his little **** on the ground like a real dog. Make him sit and stay at the door – spinning around like a nut is not okay either. Small dogs are fragile, so rather than a leash tug, try a spray bottle of water in his face or a ****** of lemon juice in his mouth – find something he just hates. Use a correction word like “ATT!” and repeat your quiet command “STOP!” Ask you friends to come over and help you. They’ll probably be delighted to help – they probably **** it as much as you do. Practice for at least fifteen minutes straight, every day for a month or two. Even the most determined yapper will eventually give up. Invite people over more often, so you can practice teaching him how to behave.

If he barks in the crate, slap the top with the palm of your hand of shake the crate.

If he’s barking at people because he’s afraid, then get him out and socialize him with as many people as you can, so he will see that they are not a threat. Put him on a leash and start inviting a LOT more people to your home. The more he gets used to people coming in, the better he’ll be. Show him that you are secure and in control and he won’t feel so worried. Don’t worry about ruining him as a watchdog – he’ll still defend your property from anyone trying to break in.

If he’s barking inside when he sees people passing, then I’d cover your windows with opaque film so he can’t look out. If he’s barking outside, put up a solid fence instead of chain link so he can’t see as much.

If he’s barking at everyone he sees while you’re out walking, the you need to do some obedience training and get control of him.
