Slim I’ve freeze branded a few dogs, horses, and cows. Naturally it a different hold on time for each. I used liquid nitrogen though. Usually on a dog the hold time was about 6-8 seconds depending on how thick the dogs hide was. Getting the hair off is a big deal, where there’s not even any stubble if possible. Then the purest alcohol to clean it. I’d rub it pretty good to get any oils and dead skin of. I made a template out of cardboard that the outer edges of the brand would almost touch so that I could put it up to the animal and move it around to where it fit best and I was going to be able to get the whole brand to make contact. When I figured out where that was I traced around the template with chalk and then took clippers to it. Right before I put the brand to it I would spray it with alcohol again. Making sure the animal can’t squirm or run away from you is huge too because it’s super hard to get the iron back in the same exact spot. When you pull it off, usually the brand will whelp up or raise within a few seconds if I remember correctly. Like I say, that was with the nitrogen though. I have a tank that I would go get nitrogen in but pour some over into a styrofoam cooler to freeze the iron. I cut a slot in the lid for the handle to stick up through and wrapped a towel around the handle where it stuck out to hold the cold in the cooler and keep the nitrogen from evaporating. I’m sure you know but if you hold it too long, the brand will look like a hot brand. It will kill the hair follicles instead of just the pigmentation. That’s what they do on animals that are white usually.

You can on this one that I should’ve rocked the brand around better. Because of the muscle there, it the brand wasn’t held firmly enough against him on one side to take.

This one took better. These were a couple of the first ones I did.
