My dog has a patch on the tip of her ear that looks like a build up of something. It is dry and hard. I started picking at it and the hair started coming part. What is this and how do I help?
She also has other spots on her body that are just dry and thinning hair. Is there anything I can do to help with hair loss/thinning? Anything topical? We were told she may have an allergy to chicken so she is on a sensitive diet.

I have a small dog treat bakery side hustle and would like to include small cakes, donuts and muffins in my treat line. Cake like recipes call for baking powder, baking soda or both. Is there any amount that is safe? Where would I find solid information on the use of these items in cakes for dogs?

I’ve tried using eggs for leavening but things like donuts are still brick like – and yes I taste each item I make!

Thanks!
