Before you buy a no bark collar, consider why your dog is barking. A barking dog may be lonely or suffering from separation anxiety, or it may really be barking at intruders or something that doesn't belong in your yard. Some trainers say that using these collars on a dog that has separation anxiety may not be a good idea. The anxious dog may associate the correction from the devices with being left alone. Using these on the anxious dog may just cause a more anxious dog.

One model of no bark collar responds to the vibrations of the dog's vocal cords. Another model uses a microphone and corrects dogs because of sound. Whichever you buy, they all work basically the same way. When the dog barks, they emit a mild electronic shock. Correction from bark collars continue if the dog keeps barking.

There are many types available. Some have levels of correction that you set. If the no bark collar has eight levels of correction, but you know your dog will be adequately corrected at level three, set the units at that level. Specialized models with this feature give you complete control over the dog. Another model has stepped ranges of correction that automatically increase as the dog continues to bark.

If your dog stops barking, they reset and correction begins at the lowest level when the dog barks again and give a mild electronic correction that is similar to the feeling you get when you touch a door knob after sliding your feet across a carpet. The right units give an annoying, not harmful, correction.

Another type of unit is the citronella spray bark collar. Citronella collars emit a spray of strong citrus scent when your dog barks. The citrus scent from this model is very strong to your dog, because of its strong sense of smell, and offers a distraction without any physical discomfort.

Eventually, the no bark collar will become unnecessary. Your dog will associate correction from the unit with bad barking and will learn to bark only when necessary.

They can be used on any dog that knows basic training commands; even toy breeds can wear a small unit. They are light-weight, weighing as little as several ounces. Some models are water-resistant, others are water-proof. Some models even have a bark odometer that tells you how many times the dog barked during the day. Although trying to stop dogs from barking may be a difficult task, you can be sure that it will be easier with a PetSafe Comfort-Fit Bark Control Collar.
