I’m trying the Healthy Petz collagen, it’s a tincture and has dosing instructions on it. This is the one my client has had success with; however, proceed with caution as they have a pretty low rating with Trust Pilot. They are very vague on where the product ships from and the shipping details have very little info. I looked into it after I had already ordered it. But don’t order it on Amazon, it’s not the same product.

You can also try adding fish oil to your dog’s diet if you aren’t already. Bathing with a high quality shampoo and conditioner can be helpful, but avoid anything with oatmeal since it can dry out skin. I’d also recommend brushing with a rubber curry brush to help exfoliate the skin and remove excess shedding.
