Caught Hog Question

I have never thought about ahving the dogs "roll out" after the pig is flipped unitl I got here and heard it mentioned. I keep my dogs close to me so once they get one I respond and then claim the pig and they back up and let me do my thing whether it is gut and clean or cut and release. I tie my young dogs up the first few times until they figure it out and after I release the pig or get it packed up I continue on my waya dn then they go back to working. This is the method I have always used but I guess if there was a group of pigs then it could be beneficial for the dogs to hunt on after I reach the first one.
