what’s a dog food you’ll be purchasing?

hello,

My newly adult dog was doing really well on his previous kibble (Acana), but after a while it started to give him the poops. We went back and forth to the vet and narrowed it down to being food related. She suggested we try some other brands. So we are now on a new food which have resolved his issues down there, but I can’t see them being long term because it’s more of a boutique brand. Initially I just wanted to see how his body digests food curated in this format. What foods do you all recommend?

Thanks!

Edit: I just checked my phone after finished work and floored by the responses. Thank you for taking the time - I am going to read through them all!
