I base my opinions on what Ive seen with my own eyes,I grew up around heads involved in the pits in the 80/90's,I never personally got the whole fighting dogs thing,found most involved in it a tad strange tbh,but each to their own.Ive seen enough pure bulls,presa,bandogs,ebts that couldn't do, what a decent lurcher can do around a hole,week in,week out, consistently ....could kill other dogs for fun,but not brave enough to travel a tube and draw something out a 1/3 of its size and kill it quickly....a working terrier is not evenly matched to its opponent,like a pitdog... That dog can be save
