Welcome Dustin! I actually have something that has worked great in helping my parents dogs that are prone to get hotspots. My wife and I make a tallow balm, the recipe I’ve posted elsewhere on the forum but I’ll copy here. The herbs we generally use in it are comfrey, calendula, and lavender.

Here is the recipe

1 cup tallow
1 cup dried herbs (by volume)
1.5 tbsp olive or coconut oil (optional)

You melt down the tallow in a pot on low, and once it’s a liquid add in the cup of herbs (by volume) and let it infuse for an hour or so keeping the heat on low. The recipe we originally found (from milkandhoneyherbs) says that the longer you can let the herbs stay in there the better, but we felt an hour was long enough. Once you’re done with that, you’ll want to strain the tallow so you don’t get a bunch of herb chunks in your new balm. By recommendation of someone else here on the forum, we put a thin towel inside of a potato ricer and strained everything through that. Also, if you want to add in the oil, here is where you would do that, it just makes it have a softer consistency. Here you have a couple of options, option 1 is you can just pour it into little containers and let it cool, and then congratulations you’ve made your balm! Option 2 is to let it cool a bit to where it is still in liquid form but not hard yet, and use an emulsion blender and whip it up. We’ve done both ways and found that using the emulsion blender is really nice because it makes it all into a nice, smooth lotion. This really is an excellent skin healer and I cannot recommend it enough!
