So I have a 10.5 year old pit Terrier mix who has bad digestive issues. I’m moving him from hills science diet sensitive stomach to hills Prescription I/d dry food this week(he loves the wet food but it’s way to expensive). I’m also adding some vegetables to his diet. I’ve started adding frozen green beans ,carrots, cucumbers, and pumpkin Totaling about a cup all together to his morning meal along with the hill science diet about a cup and a half (soon to be the I/d) and for his night time meal right now is half a can of the wet i/d 1 1/2 cups of the sensitive stomach (soon 2 been just dry I/d) a small amount of frozen kale and about 2 teaspoons of salmon oil. Is this ok or could I be doing more harm then good.
