I have been using Omega Horseshine and Omega Nibblers for years.  I think both products are outstanding.  My mare loves the Nibblers and I like the fact that I can break them up into smaller pieces and put them in my pocket for an always accessible treat.  They have done wonders for Pearl’s feet and coat.  She is grey and even in the middle of winter, with a huge fluffy coat, dirt, and mud ground into her fur, the sun just glints off of her.  It is truly amazing.
