Having two small inside dogs a bark collar is just about a must or at least it is in my house, they seem to bark at every sound they hear and if we have company over it is very hard to keep them quiet so we have to use bark collars on them.
This Bosco Knows Bark Training Collar is different from all of the others we have purchased, this one comes with interchanging faces that you can trade out if you would like, this is the first time I have seen a bark collar made like this and I really like it, you can trade between the blue and the orange facing. It is easy to replace as you just pull it out and pop the other one in place.
This collar is safe to use on your little fur buddy, it doesn't shock it just sends out vibrations and sounds to deter your dog from barking. The collar is adjustable and it also includes an extra set of probes, one for short haired dogs and one for long haired dogs, there is also a little plastic piece you can use to change out the probes. A battery is also included so it is ready to use when you receive it after you put the battery in and decide which set of probes suits your little buddy.
