MR PITBULL SAYS: DISCARD ANY NOTION THAT BARKING COLLARS ARE INHUMANE
MR PITBULL SAYS: BARK LIMITER DESERVES MY HIGHEST RECOMMENDATION
THIS IS THE BARK COLLAR I USE
I will never forget the first Barking collar I bought; because of a poor design it would shock the dog when he was not even barking. The next Barking collar I bought literally burned two holes into the neck of one of my dogs where the contact points touch. The next Barking collar I bought had re-chargeable batteries that needed to be re-charged about everyday. The next Barking collar I bought worked nicely until it rained.
ANOTHER ANTI- BARKING COLLAR YOU MAY WANT TO LOOK AT
Another idea, instead of buying a Barking collar; use a remote training collar. For many this works perfectly. With the remote training collar, when the dog starts barking, you have to use the remote to stop the dog from barking. With most dogs, after he has been corrected a few times the barking stops altogether. If however your dog continues Barking while you are not home, then you need an anti-Barking collar.
If you have any doubts about using a anti-Barking collar, do yourself and your neighbors a favor, and read REAL PEOPLE REVIEW BARK COLLARS. Even the reviews with 1 star are very informative.
