I was joking but I think every one else is serious. I've never done it but I bet it works for sure. My wife has a cosmetology license and says alot of folks use preparation H for lot's of stuff. Especially drawing the skin up. Even bags under the eyes.
I may try this prep h to speed up my dogo's draw up process but what has worked for my bitches over the years is when they start to get sick of the pups (5 weeks on avg), I separate them and only let them nurse 1 or 2 times a day for about a week, then after a week or so of that I fast the bitch for a day, then only feed her a very small amount of food with extra nutrients like eggs and olive oil and vitamins included in that small amount (1/2-1 cup sport mix or victor etc) for a few days and they have always dried up quickly for me with this method. I will them give them extra feed and eggs etc to catch them up on weight after they dried up and get them back to the woods asap.
I also road them a few times to get them legged up again before hunting typically or use them conservatively the first time or 3 back. FYI I dont care what the old timers etc tell you dont use canola oil despite the shiny coat its not healthy use olive or coconut oil and eggs or sardines
