Have had no problem with it. Was recommended for my dog by Dr Donna Gigliotti, chiropractor at Western Lehigh Veternary Hospital
When I saw improvements for one cat I started giving it to all my cats.
Canine Renal Support, 3.9 oz (110 g)
I have been using this product for years. It really helps with my allergies and tearing eyes!
This is an excellent source of vitamin D however it may require additional supplementation or taking more than two a day
