I can tell you have a TSC lol.
Ultrashine/ Omega Horseshine even more so, do wonders for skin and coat and then some. I saw better results with the Omega Horseshine, tho.
I would seriously think twice about both, Safe Choice and Omolene 200. Both pretty high in sugars, regardless of the name.
Either Strategy Healthy Edge, one of the better Purina feeds( don't know if your TSC carries it, mine does, so yours could order), or Nutrena Life Design senior.
With the minimum recommended amount to feed of thes two plus the Ultrashine, you don't need to add ShoGlo. Overkill. If you stay BELOW the minimum recommended amount of either feed, add 1/2 ration, one measure, of the ShoGlo.
I would do a fecal test before worming next time, and give him dewormer for what he needs, IF he needs any at all. If you keep his environment clean, I.e. pick poop, you don't need to deworm that much. Latest research shows resistent worms, and scientists have begun rethinking the prophylactic worming.
Sorry for taking the fun out of shopping, but it's really not necessary. K.I.S.S....keep it simple,stupid( not meant personally, lol)
