Much of the opposition for blood tracking dogs, stems from the same mindset that opposes change, period.
Like opposition towards MYH, more youth seasons, additional SH, use of semi-autos, air rifles and so on, it just comes naturally to some people to oppose anything different than what we've had here in PA.
Even if such things have been the norm elsewhere for years and considered perfectly acceptable.
If "we didn't have it here - we don't need it", is the response I've heard numerous times over the years when discussing such issues.
Several years ago at a meeting in Johnstown, Andy Bensing came with his blood tracking dog and a discussion was had outside during a break.
More than one person expressed opposition to the idea of allowing dogs to assist in finding wounded big game, claiming it was just an excuse to let dogs "run down" deer.
I pointed out Andy's dog, which IIRC weighs about 15-20lbs, as they were standing right next to us. Asked the loudest opponent of tracking dogs, how many dogs that size, would be needed to "run down" a deer.
