When people look into feeding their dogs, they should consider a few factors. Things like age, metabolism rate, if they are spayed or how active of a dog you have play an important part in how much you feed them.
That said, most recommend feeding their adult Belgian Tervuren 2 to 3 cups of dry kibble per day. The food should be of high quality with key supplements. Meat should be the first ingredient of your Terv’s diet. Anything like; chicken, turkey, lamb, and salmon will suffice.
You should avoid grain, cheap fillers, high sugar content and artificial flavors. Look more for food that has Taurine, Glucosamine, which helps with the bones and joint. Omega 3 and 6 will help promote healthier coats and skin.
Feeding your dog twice a day will help reduce the chances of them inheriting bloat or Gastric Dilatation.
Also, if you have a 55 pound light duty working dog, then feeding them 1400-1600 calories per day will suffice their needs. A 75 pound dog with the same activity level will need 1800-2100 calories per day.
Finally, you should always make available to your Belgian Tervuren clean drinking water.
