I wouldn’t worry yourself over staying within the brand, that’s a bit of a myth. I switch between brands with every bag, and i don’t even bother to mix them unless i dont have enough left to give a full meal. Depending on how you switched though if your dog isnt used to a rotational diet, you may have switched Acana too fast, as that is a fair amount lower in protein than orijen (which i can’t use either) I do like acana, though alot if their kibble sizes are a bit big for my liking.
I don’t recommend blue buffalo at all-any line of them. sketchy company, if you nose about on the forums you will see a lot more in depth comments about tham
Some dogs dont do well on certain proteins, so that could have been the case with the beef there, though it could have been changing him too quickly if he isn’t used to it.
As far as that range of protein %, I would try out Fromm, especially the 4 star line, they have plenty of flavors to pick from. I also like Earthborn, and the small breed i use a lot in my rotation as I have one that has issues with peas so a lot of grain free blends don’t work for us (though sometimes I just buy her a separate bag and the other 2 can share) but the Earthborn grain free line is a favorite of mine as well, though it’s a bit higher in the protein than what you are looking for. Go! is manufactured by Now Fresh and they have Now Fresh and Summit you could look into. Nature’s Variety prairie is a bit lower and from a solid company, precise is a good company…you will find that in the 20%s for protein, you probably won’t be at 5 stars, but as long as the red ingredients are kept to a minimum, i wouldn’t balk at the food if it’s what you need to do for your dogs stomach
