How many have crossed a pit with a jagd terrier

I own 3 Jags, two males & a female. They can be out together only when I'm home. In order to build on their pack drive/bond I feed all three together. But this takes training. First you must establish that your Alpha. The way I do that is get a bowl of dog food and set it down. Those that own Jadgs know this is a hard thing with two much less three. But if they come near I jab them with my fingers/open hand in the neck & use the command "Back", when they back off & are waiting at a distance. I pour the bowl out then say "get your food". I sit close and watch. I watch for lip curling, growling, tails stiff and straight up, & hair sticking up. These are tell tell signs of a fight or attack coming. If I see it I make a correction fingers to the neck while saying No. I stay there till all the food is gone & pet each dog while they eat. I do this at every meal. I believe Jags need to hunt as pack animal. This is the method i use, good luck to my fellow Jagd owners. Now like I said I only have them out when I'm home and separated when I'm not. I have had the male dogs get into it during the females heat. These dogs are a handful, but I would will always have one in my pack. My goal is a taller more bone Jagd. I have a buddy that knows of a male(the sire to one of my males) that is closer to 40lbs, & several inches taller. This male is opposite of my other terriers. Loves to be close to owner, but when out in the field hunts just as hard as the other two. Verses nothing to do with you all hunt.
