I have one that when I feed venision she has a nice black runny poop the next day!!!!
I have a couple who tear also and have not noticed any improvement as of yet,But the teeth do look better and the breath does smell better.
My skinny picky eater has gained weight,and my tea cup of 15 pounds is slimming down
I leave out NV kibble for I do have one who really does not like raw,(she is getting better)and a pg female also who is really picky right now and want to make sure she is getting all she needs,Noone seems to touch it much though
but it is there if they need it.
I just wonder with her being pg what else I should be giving her? (on raw)
