I recommend a Premium Dog Food brand that is NOT grain free. If you change food, make sure the transition is gradually to not upset the puppy’s digestive system. For the first 6 months please add probiotics, such as Forti Flora or any other brand.
I prefer to feed my dogs Pruina ProPlan as this food is formulated by certified nutritionists and based on scientific research. It also goes through several quality controls. Stay away from “designer foods” with pretty labels. This is my personal opinion, you can certainly feed another brand. Also, check food brands (treats) for Rosemary extract. Rosemary have found to possibly trigger seizures.
For puppies up to 1 year a puppy food 28g protein, 14 g fat. After a year of age a 26/16 formula maintance food is perfect. Too high protein levels for puppies can cause too fast growth, which has an impact on bones and joints. Unless your teenage, adult dog is a hard working “sled dog” there is no need to feed a sports or high performance food. A good indicator that your dog is at a good weight is, feeling the ribs. If you can feel the ribs with no pressure applied your dog is in perfect shape. Sometimes it can be hard to keep weight on young Belgians. They just burn it off quickly. In that case I would change temporary to higher fat content, such as performance or sport. Dogs that are neutered or spayed tend to gain weight quickly. Once the dogs get over weight, it is pretty hard to get it off. In that case a lower fat diet is better. Feeding the dog less of the same food means the dog gets less vitamins and other nutrition their body needs. It is better to buy a “weight control” food. There are several on the market.
