How to break rottweiler's tail!

Hello, under normal circumstances, puppies can cut their tails two or three days after birth. Tools needed are valve core, hemostatic forceps (used to open the valve core), iodine and cotton. First cut the valve core into a length of about 5 mm, disinfect the dog's tail with iodine, and put the cut valve core on the broken tail with hemostatic forceps. (Leave three tail joints, which are basically 1/3 of the tail, and must be the middle position between the joints). Disinfect after it's over. Disinfect several times a day. If the method is correct, the tail will naturally fall off in a few days. If you are worried about the failure of tail cutting, please ask an experienced person or a professional pet doctor for help. I hope the above answers will satisfy you!
