I haven't had it happened yet but ive been thinking but cant wrap my head around it is how the heck do u get a catchdog off a cow? And also howcan u train or teach a dog to avoid large running water. So they want drown.
I had one catch a cow that my buddy's dogs bayed up...We were unloading dogs and I let the bulldog out so he could empty out. He heard the dogs barking and he dashed for the bay and he caught the cow and it took a while to get him off...long story short...I could never break him off of cows after that...not to mention he lost his canines on that deal...
I tried five or six times after that episode using full power on the collar but he couldn't be trusted going through cattle after that...before he caught that cow he used to not pay them any mind and he was broke off cows but when one is bayed tight I believe any bull dog will catch in the heat of the moment...
