Are there any natural over-the-counter products or supplements I can use on my dog's skin?

Fish oils would be the first one that comes to my mind. While there are veterinary options, you can probably find very comparable OTC products as well. Beyond that, not really. Topical things, yes, but anything oral additives? I wouldn't think so. I would discuss that with your veterinarian first before trying any kind of at-home remedies.

First off, I'm not a huge fan of topicals in dogs. We use them periodically. Dogs are great lickers, and when they lick, they remove the topical, and it may or may not be healthy for them, and that is usually the case. The other thing is when you apply a topical to a bothersome area, it just draws their attention to it even more. It's like if you have poison Ivy and you scratch it, it itches worse because you drew attention to it. So I'm not a big fan of topical. However, I'm a huge fan of the omega three and omega six fatty acids, which can help to supplement the skin's protective barrier and helps to take away inflammation. They need to be formulated for pets, and there are some good products out there. The Bayer free form is my favorite, and I feel like it's the most effective. But use one specifically made for dogs. CBD is becoming a question more and more for us. Unfortunately, here in North Carolina, we really can't comment on CBD. We're not even allowed to legally. Let's just say that nothing I have read has shown me that it can help with skin issues, but the jury's still out. There's a lot of research still to be done. People think coconut oil and CBD cure everything, so just try it. We don't really recommend that.
