There vest are the only ones I will use!!! I have tried the cheaper vest and was never happy! Currently use there Titan vests and I can't complain they have held up great through a lot of hogs!
A couple years back the game wardenS caught one less than a mile frOm my house that was just shy of 9 feet long and turned it loose in a lake that's only a mile and a half from my house! I live in Southern Oklahoma.
I've had this problem on my main strike dog once. used ivomec for 60 days straight and then tapered off slowly. All his hair grew back and he stills looks and hunts great about a year later with no more outbreaks.
