The Innotek BC-50B no bark collars were introduced in 2003. It features a set it and forget it technology. This is an over simplification. These no dog bark collars not only control barking but teaches the dog not to bark as well. The collar actually will increase the stimulation as the dog continues to bark over 7 different levels, until the barking is controlled. Most important is that it also decreases the stimulation as the dog learns not to bark, again over seven different levels. Plus it provides a 2 second learning time out between stimulations. The result is a dog that learns not to bark with an achievable goal of removing the bark collar several months in the future. This makes no bark systems like this an excellent choice. The collar receiver is standard size and is appropriate for dogs over 20 lbs. and uses a commonly found 6 volt alkaline battery, and is potted for durability. Potted refers to the process of injecting a soft foam which hardens around the delicate internal electronics, protecting them from damage. These no bark systems are a dog specific, other dogs will not set off the correction, only the dog which is wearing the collar.

The PetSafe PBC-102 are conventional no bark collars that will automatically increase the level of stimulation until the barking stops, but does not decrease the level. The collar receiver is a small making it acceptable for dogs as small as 15 lbs. However, it is battery replaceable with a proprietary 3 Volt battery module, only available from PetSafe dealers, so beware. Hence, if customers are going to purchase a PBC-102 we recommend a few additional battery modules at the same time. We do caution that this is not a waterproof system; hence it should never be submerged in water.
