Although the recipes are the same, the plan continues to be customized by a veterinarian, and tailored to your dog.I would like to explain why:The nutritional requirements for senior dogs, according to FEDIAF, which indicate the amounts of each nutrient that must be present in the diet, are exactly the same as for adult dogs.The only difference is in the energy requirements, which are different because, as a general rule, the recommended daily dose of food in the senior stage may be lower than in the adult stage.That's why Barkyn recipes can be adapted to senior or adult dogs, although there is a difference in the daily dose recommendations to be consumed.I would also like to share with you that recipes for senior dogs should have a good amount of B vitamins, a source of omegas and antioxidants and be moderate in fat.This is also the case with our adult recipes (we want the best for each dog at every stage of its life).Therefore, there is no need to worry: the recipes are safe and indicated for adult and senior dogs, with the necessary adjustments in the recommended daily dose.
