Is this food a good brand to feed my dog?

These are dog treats and not very good ones at that. Find a good quality meat based diet. There are several of them out there. Livestock feed stores have some really good brands for good prices like Exclusive or Diamond Naturals. Sounds like these dogs have some severe medical issues. So you might really want to consult with your vet. You need to increase the quality of the food that you are feeding and decrease the amount that you are feeding. Doing so will save you so money so that these dogs can be examined by a vet.
