Running Catch Dogs

Black streak you are right on the smaller dogs but why does a dog have to catch on the ear to be a catch dog or have to be a certain breed wolfhound great dane mastiffs all of these dogs could be catch dogs but the most common dogs that are consider catch dogs are ab dogos or pits a german Shepherd could be a catch dog they have size mu smaller dogs don't hunt miles away they run 100 to 200 yard loops we walk hunt in the mountains I can't lead a bull dog for 5-10 miles then pack a pig out while holding on to a dog at the same time also they grab ass until I get there then call um off the ass to the ear so I can poke the pig if.my dogs use chest plates not full vest and yes some people like to put tons of kelar on there vest but I don't why because I am not letting my dog hold a pig for a lot of time as soon as they get on the head I got the legs I run grayhound German Shepherd x over cat these are all bigger then a bulldog I also run wippet x cat they are smaller dogs but will out run almost any pig or dog for that matter but again the smaller dogs only run a short way the long out they go the longer I have to pack out the pig that's why I don't like mile dogs also can you run a bulldog 3 days in the mountain catching pigs walking miles pulling around a person up and down hill and catching pigs I am not knocking bull dogs I just got one to hunt in texas but that's because it's a different type of hunting also if I am hunting open pastures on a bike I can be on my small dogs and pig fast so there isn't to much damage done if any it's just a point of view of someone that does run small dogs and does catch pigs and needs that type of dog to catch good pigs and my dogs will grab anything but like I said only on the ass till I get there I am not trying to be a smart ass know it all
