What Are the Dangers of Obesity for Dogs?
Showering your dog with treats might be your favorite way of showing him you care, but what you may not realize is that you’re actually doing him harm. Gaining even a pound or two can be significant for a dog and being overweight or obese can shorten your dog’s lifespan and increase his risk of disease.
Obesity isn’t just a human problem. In fact, Dr. Justin Shmalberg, DVM and veterinary nutritionist for fresh pet food company NomNomNow, states that up to 60% of dogs are overweight and nearly half of those are obese.
Here are some of the risks associated with canine obesity:
- Chronic, low-level inflammation that contributes to other diseases
- Increased risk for developing type two diabetes
- High blood pressure and other markers for heart disease
- Osteoarthritis and increased joint degeneration
- Increased risk for urinary bladder stones
- Reduced tolerance for heat and exercise, and other respiratory issues
Not only is obesity one of the most common medical conditions seen in dogs, but it’s also one of the most preventable. Meeting your dog’s calorie needs with a high-quality dog food, without going overboard on treats and snacks, is the best way to keep him healthy.
If your dog needs to drop a few pounds, switching to a weight management formula might help.
What to Look for in a Low-Fat Dog Food
When you want to lose weight, you probably eat less and choose low-calorie options. The same principle applies to weight loss in dogs, except that you’ll be the one making the decisions.
As difficult as it might be to say no to those puppy dog eyes, it’s in your dog’s best interest!
You shouldn’t simply cut your dog’s feeding amount in half, however. Drastically reducing your dog’s food intake might achieve the desired result (weight loss) but less food means fewer nutrients. If you’re feeding your dog well below the recommended volume, he might not be getting the nutrients he needs.
Switching to low-fat dog food or a weight management formula is a better option.
Look for a recipe that is rich in whole animal proteins to help your dog build and maintain lean muscle mass. Extra fiber and moisture content will help your dog feel full while boosting digestion and reducing calories. Make sure your dog’s minimum dietary requirements for fats are met (minimum 5% for adult dogs) without going overboard—something at or under 10% is ideal.
Low-fat dog food is a great choice for dogs who need to lose weight, but it can also be a dietary necessity. For example, dogs with pancreatitis or irritable bowel syndrome (IBS) may have trouble digesting dietary fats. Switching to a low-fat dog food could help manage these conditions.
