I have two dogs with a sensitive stomach. The other one gets acid reflux from some kibbles. Both did fantastic on Maxi Digestive Care. No stomach problems, no acid reflux. Shiny fur, good energy. Small firm stools. Went through 4 15kg bags of it. Would absolutely buy it again, but my budget doesn't allow it right now. That's the only reason I'm not giving it 5 stars, because it's just too pricey compared to several other brands! Otherwise it was a great experience.
