ok,

 

The first thing I would recommand is having him tested for intestional worms as this can be the leading cause of weight loss in dogs and will cause a fat tummy.Worms can also cause anemia and other health issues and can lead to the death of a pet. You may be able to just drop off a stool sample at your vet.

 

If you place him on heartworm prevention such as heartguard this will also deworm for intestional worms monthly.

 

I would also recommand finding a food he likes and sticking with it, it can cause extreme stress on a dog gastrointestional tract when you switch foods. Dogs do best when maintained on a regular diet.

 

I suspect he probably has intestional worms which are causing him to not absorb all the nutrients in the food.

 

You should have this checked as soon as possible
