Hi Froggy, in 2005 I bought a pedigree blue cattle dog pup for my youngest son, beautiful dog but no matter what you did training wise it barked and I mean barked, I had its vocal cords cut by a vet but it still made enough noise to really annoy neighbours, he also had an electric barking collar but just ignored the zap and would just bark , loved to fight as well and fought every dog he could, we ended up giving him to a breeder I knew and from what I heard he flogged him, I should have just put him down sadly..
