Sory I haven't answered back - family crisis involving a broken back (not me). Anyway...
I tried several different feeds and am now sticking with TOTW Pacific Stream. For the meds we did the motronidazole, Panacur (I think) powder, and steroids, etc. I used the following supplements: Missing Link, ProZyme and another brand from the vet (forget the name) and fed yogurt with active live cultures.
I can tell you I checked the labels and did my own comparison of the supplements. The total Zyme and Total Biotics had all the others beat by a mile if you compared types of enzymes and especially the amount/concentrations of each enzymes/probiotic.
Sorry if this is not very helpful. It has been a long stack of months and once we got on the right track my mind seems to have forgotten all about the ones that did not work for Tyler. If you do think about ordering some I can give you a tip to assist with the dosage "math": the scoop holds 1/4 tsp if filled to level. So 1/4 tsp treats 1 cup of food (any form - RAW, kibble, etc). Thusly, Tyler gets one cup kibble 3x day. He gets one scoop (1/4tsp) per feed so he takes a total of 3/4 of each powder per day. The rough math worked out to each jar should last me 3 months.
