Many factors could affect your decision to transition your dog’s diet to a low-fat one. It can be as simple as wanting to ensure your dog’s body stays fit and healthy, or it also might be because your pooch is experiencing a medical condition that requires them to lose weight. Well, whatever it is ‘s best to be familiar with the most common conditions to determine why your furry friend needs low-fat dog food.


Spoiling your pooch with treats may be fun (for the both of you) at first because you get to see your fur baby happy, and for a paw-rent that’s one of the most rewarding things ever. However, overfeeding your dog can have adverse effects on their weight, leading to weight gain and obesity. Compared to healthy dogs, obese dogs are more at risk of developing arthritis or pancreatitis. In some cases, obesity is also believed to be connected to heart disease and high blood pressure.


Pancreatitis is an inflammation of the pancreas. The pancreas helps digest and break down food that goes in your stomach, and having an inflamed pancreas disrupts the whole process of the digestive system. This means that whenever your dog eats, they will have trouble digesting carbs and breaking down fats, causing pain in your dog’s stomach. Based on American Kennel Club, symptoms of pancreatitis include abdominal pain, diarrhea, vomiting, lethargy, fever, appetite loss, and dehydration.

Sensitive Stomach

Dogs with sensitive stomachs tend to have messy bowel movements and smelly gas. Low-fat dog foods help in aiding your dog’s sensitive tummy. Having less fat to break down also means lesser unpleasant trips to the toilet for your fur baby.
