Hi, in regards the VASQUEZ style restricted restraint collar, you have to give the dog a little time to adjust to it, it is meant to restrain but also for the dog to adjust to the noise, after a short period of time you will see that the you will NOT have to CHECK , by actually lugging back on the lead, as the noise plus, sensation of the WEBBING or Leather closing around the neck area ( opening of collar MUST be EXACT measurement of dogs neck NOT LESS , NOT MORE) induces the desired result, they are a very very effective restraint, but like anything else, change takes a little time to adjust to it,
now just some trivia on why I moved over to VASQUEZ, is the SALIVA gland damage resulting from OVER ZEALOUS CHECKING with a Check chain type restraint
if the Choker/Check chain moves up to high on the neck towards the ears, and you apply enough pressure, that Saliva gland can be damaged, which results in HUGE amounts of TARTAR and calicum build up on the SIDE that isn't damaged, plus the fact, once blocked , that gland causes a whole heap or trouble, I seen it personally in a Bull Terrier, and also a Ridge back cross, and in both cases the end result was surgery, and you havn't even thought about the Trachea area etc,
the VASQUEZ should be OPEN / LOOSE at all times, until a check in introduced,
it is a great gadget, I have had deliquent dogs that pull like crazy on a Check / Choker till they are hoarse, and worked 1 hour with a VASQUEZ and have them calm, collected, no distress, no hoarsenees in their breathing etc, different animals..
THEN YOU TEACH THE OWNER hahahah
