I would go with the Wellness , Eukanuba is really a very poor quality food and could be causing her gas and mulitple poops. While on Wellness I could just about schedule my puppys poops one time at 7 am then shortly after dinner around 6. Wellness is really a good quality food and will probally help with both the poops and gas
Another good food is Merricks puppy plate, because you can add water and it makes a nice gravy so its softer and easier to chew.
