Waiting to see if it helps, update

So far, Shelby doesn’t mind the taste and it’s easy to figure out the dosage.
I’ll update after a month to let you know if it works.
Well, Shelby has been taking this now for over a month. I’ve seen a positive reaction to this supplement. She had 4 small fatty tumors that have almost all disappeared. She has 2 fatty tumors that have gotten a little smaller in size, but are still are able to see. They’re not as uncomfortable for her (she doesn’t mind if you touch them while petting her), which is fantastic! Her allergies are better and she’s eating well again.
So, over all, this supplement seems to work as advertised.
Shelby is a 12yo English Lab, my service dog, lifesaver and best friend. I’m so thankful this is helping her. I can’t imagine life without her!
