Fat content, depending on what clinical research you read, suggests a 15%-19% ratio. Lowering the fat content for animals who are without chronic issues, may induce other issues with their health, such as skin and allergy disorders. Imbalances within the protein to fat content, cause nutritional imbalances within the dog.
As you have specified that your Schnauzer has pancreatitis and is on a special diet, I would not include your new yorkie on it as well. If she is not receiving the "nutritional fat and protein requirements" for her body, then she will continue eating more until she does. This continuous eating will lead to serious weight and health issues. This is one of the main causes of Pica in animals. This "nutritional-starvation" is represented by a continuous hunger, which directs them to eat everything .
Also, on a low protein, low fat diet, most of the Kcal and the nutrients are coming from carbohydrates, which is not really a good thing. While carbohydrates are great for feeding all the muscles of the body, they are not great at building and maintaining them as they are not as "nutritional dense" as proteins and fats.
Hope this helps. |
