Getting alot of pm's on how to brand so I will do a quick run down.
1. you need your brand, Brass or copper works the best. I got mine at

2.get your liquid Nitrogen, I just use a styrofoam cooler ( tape around lid when transporting) I cut a small hole in it so that I can close the lid with the brand in it. Liquid Nitro will evaporate when exposed to air.
Cost me $6 to do 16 dogs
3. you need Isopropyl Alcohol I use 91%. Walgreens or any supermarket
4.Clippers
5.Gloves
6.Electical tape
Now you have everything you need except help, it is nice to have two people holding the dog and one person branding.
1. Put brand in liquid Nitrogen
2. Tape the dogs mouth shut so he doesnt bite you .
3 .Shave the area to be branded , you get a cleaner brand and gets colder
4. Put a small amout of alcohol on the shaved area ,enough to cover the branded area.This makes it colder.
Your brand is cold enough when it has stopped bubbling like it did when you put it in.
5. My brand is pretty thick so I only put it on for 7 to 10 seconds and that is on the body.
Push pretty hard so you don't get shadowing and slightly roll it to get good clean edges.
6. Put brand back in cooler and get ready for the next.
I don't brand ears, because they can be cut off so I don't know how long to leave it on for the ears.
