My Boston Terrier is prone to HGE and has a very sensitive stomach. Years ago I went looking for a "premium" food and put him on Nature's Recipe Lamb Meal and Rice. I chose this one because it did not contain chicken, as that seems to have been an issure for him from early on. He seems to get an upset stomach more often lately, and I found that Nature's Recipe had changed it's formula and now contains chicken. I seem to be battling his onset of diarrhea constantly, bringing him back around as quickly as possible. I have started adding a bland canned food to his regular food, which does seem to help. But still, it seems we are on this constant roller coaster trying to avoid his upset stomach. Barring a change to ultra premium food, which my income will not allow me, what other options are there? (Mickey is 10 yrs old).
