The National Cattledog Association, in whichPF competes as a breeder, stopped listing the breeder names on their website after the 2014 National competition.

and RanchWorld.com, where PF occasionally advertized or was mentioned in advertisements, doesn't archive their ad content. Trudee just happened to catch one that was sold, before it was pulled. That dog was a two year old in April 2018, which would likely place it's birthdate in early 2016. In the furthest stretch, late 2015.

It seems to me that cattle dog breeding and training is pretty much a word of mouth business, and if a trainer has one spectacular video of full length on SM to show his product, how often does it need to be updated or replaced?
2014 wasn't a long time ago. I believe that was the same year Ford announced the 2019 return of it's iconic Ranger pickup that it started taking orders for in December. A little bit of good rep seems to replace a lot of expensive advertising, if your principal buyers are westerners. IMO
