Handling a Rally

I've never done this but i've seen a video a guy had some years ago and it worked pretty good for him. I know it will make the ol butt hole pucker a bit lol BUT it did work for them. They used two bulldogs both tied to lariat ropes and would let the dogs go and grab a hog then pretty much yo-yo the dog and hog out of the pack while their currdogs stayed working the rally, they tied 9 hogs out of the group this way before it busted.

I would be VERY careful sending a bulldog into a rally of hogs, me and a buddy sent 2 bulldogs into a rally of hogs that from what we could see/tell were primarily big sows w/ pigs one night north of jasper and we doctored those two dogs for almost an hour, once they ran in and caught all the other hogs slammed em/ bit em/ cut em, those two poor bulldogs got flat out whooped on. I ended up pulling my pistol and firing it multiple times to get the hogs to break and we managed to catch 3 out of over 30 head but those poor bulldogs got whooped like ive never seen, they had big patched of hair/skin completely missing and im almost 100% sure it was those big sows running into em and biting them while they were caught on another hog. if you aren't prepared a rally can get real western real quick! I know theres a few guys on here that have talked about baying big sounders in the past, hopefully they will see this and give some better insight as to how they do it.
