If conventional yelling methods have not stopped your small dog from barking, the next step may be in order. Many dog training tools are on the market, but the cheapest and easiest dog trainer available is a simple collar. Types of bark collars for small dogs include ultrasonic, citronella and the electronic or shock type. All three can be effective on your dog, but choose wisely to get the desired behavioral outcome.
Find out what type of bark collar would work best for your dog. If you feel your pet could be reformed with a simple high-pitched tone, look for an ultrasonic bark collar. If you feel you will need a little more help, you can go with citronella or shock collars. Citronella collars squirt the unappealing scent of lemon grass around the dog's nose when it barks excessively.
Look at websites that are dedicated to selling bark collars for small dogs. Sites like PetSafe and Innotek cater to small dogs. They both offer ultrasonic and shock collars. Bark collars for small dogs are rather hard to find, so you must dig deep.
Pick the size of collar that you feel would be a good fit for your dog. A mechanism that is too big may hinder the dog's ability to get around. So the smaller the dog, the smaller the mechanism. PetSafe has some of the smallest shock collars on the market.
Look at the online reviews of each individual bark collar for small dogs. Remember not to buy the cheapest bark collar for small dogs; buy the best. If you do your homework, you will find that perfect fit.
