There are plenty of training collars out there but if the only problem you have is a yappy dog, then you might be interested in Bark Control Collar. DogControlPro makes a pretty good one that you might want to try.
Unlike others this one is waterproof, has a long battery life between 6-18 months depending on use, and has an on and off switch. Easy to use but not recommended for small dogs. Has different size nubs depending on your dogs hair length and size. Has 3 different levels of control so you can choose the that will work best for your pet. I suggest starting off on the lowest and working your way up to find the right setting.
You can find the DogControlPro Bark Control Collar on Amazon.
What DogControlPro has to say about their product.
Digital Microprocessor Automatic Bark Training Collar
This is one of the only automatic bark collars on the market that is run by a digital microchip system instead of a mechanical sensor. This means no false corrections that plague other automatic collars and will only correct when the dog wearing the collar is barking.
This collar solves the 3 most often complained about problems with automatic collars.
1) It is waterproof so can be worn while swimming or in heavy rain
2) It has an on/off switch to conserve battery life
3) It comes with a lithium ion battery INCLUDED that will last between 6-18 months instead of 3 days-3 weeks
This collar is made of high quality materials instead of cheap plastic components and the difference is even noticeable to the touch.
The collar strap is adjustable for almost all size dogs and there are 3 different levels of correction for dogs that range from "timid" to "stubborn"
