Natural food supplements

[Carol]

Hi All,
 I have received a catalog from a company called Springtime, Inc. They sell
premium dog supplements, (their words) .The one I am interested in is called
Fresh Factors. Claims to help itchy skin, eye watering and redness. Holli
(my almost 6yr old) suffers from allergies. She is allergic to every thing
except humans and cats. I was wondering if anyone had used any of these
supplements and if they had good results.
Thanks for any input.
