How Can You Tell if Your Dog is Overweight?

Let’s first get a handle on your dog’s current weight and weight gain. Since most of us don’t have a scale or don’t weigh our dogs regularly, their weight might not mean anything to you. First and foremost, know an ideal body condition score [1]. This number, more than the number on the scale, will better help you determine what a healthy weight is for your canine companion. It takes into account different body types and muscle masses and will help you reassess your dog’s weight as they continue on their weight loss journey. As a general rule, when looking at your pet from above, they should have a waist. It shouldn’t be a straight line from their shoulders to their hips. Their stomach should also tuck up when viewed from the side, not sag down to the level of the deepest part of their chest (or beyond!) You should also be able to feel ribs without pressing too firmly on their chest.

Next, talk with your veterinarian. They can give you an idea of what your dog should weigh, how much they need to lose, weight-loss strategies, and walk you through body condition scoring.

After you’ve determined that your family friend is overweight, it’s important to realize how they got there. Too much human food snuck under the table? Not even walks around the neighborhood? Or a dog food that’s too high in calories? Narrowing down where that extra weight came from will help you to break those bad habits that has your pup on the plump side and get them slimmed down more quickly.

Health Concerns Associated with Obesity in Dogs

Next, we need to look at problems that excess weight can cause in your favorite couch potato. It’s also important to remember that a healthy weight range for a dog is much narrower than it is for a human, especially smaller breed dogs. A few extra pounds can literally be the difference between a healthy pup and one of these detrimental conditions.

  • Heart Disease: While it might not be artery clogging complications experienced by humans, excess weight puts extra strain on heart and cardiovascular system. Constant stress can lead to congestive heart failure and decreased circulation.
  • Diabetes: Extra fat stores can increase the chances of insulin resistance in a body. That means that they are producing adequate amount of insulin but that their body isn’t responding to it in the correct way. This increases their blood sugar, is left untreated can lead to permanent nerve and organ damage or even death.
  • Joint Problems: The more weight your dog is packing around, the more wear and tear their joints, tendons, and ligaments experience. Issues like arthritis and injuries can occur more easily and prior issues like hip dysplasia can be exacerbated by extra weight.
  • Breathing Troubles: Carrying excess weight puts more pressure on your dog’s chest and diaphragm making it more difficult for them to breath, especially when lying down. You may notice that your heavy dog pants excessively, even when not exercising, and that they tire out more quickly.
  • Overheating: The more layering a dog has, the more quickly they get hot. This is especially dangerous in dogs due to their fairly inefficient cooling system. Again, heavy dogs tend to pant excessively in order to try to cool their body.
  • Cancer: Obesity can increase the risk of certain cancers. It can also plug up their liver with extra fat stores causing it to filter less effectively.

So, what does all of this mean? For most overweight dogs it means a shorter lifespan. The extra work that this weight puts on a body can cause them to die younger.

Which Dogs are More Predisposed to Weight Gain?

Just like people, some dogs are going to gain weight more easily than others. This can be due to genetics, activity, and, of course, food. Some breeds that may pack on the pounds more easily include:

  • Сocker spaniels
  • Labrador retrievers
  • Basset hounds
  • Dachshunds
  • Shelties
  • Cavalier King Charles spaniels

These dogs have a genetic composition that makes weight gain an issue.

That’s not to say that other breeds can’t get heavy just as easily. Especially dogs that are inactive or overfed. Other causes are:

  • Old age: Dogs tend to become less active as they age and their metabolism slows down, meaning they burn fewer calories than they once did.
  • Health conditions: Anything that can disrupt a body’s normal function can contribute to weight gain. Conditions like hypothyroidism, for example, can cause weight gain.

Also, dogs that have been spayed or neutered can gain weight more easily. Not only are the reproductive hormones that are removed during altering used for reproduction, they also have an effect on a metabolism. Removing them tends to slow metabolism.

  • Medications: If your family friend has ever taken corticosteroids for a skin condition, you’ve probably seen the effects some medications can have on weight. Some medications that we give our dogs can increase their appetite or slow their metabolism.
  • Inactivity: If you don’t move as much, you don’t burn as much. Dogs that are inactive due to injury or unwillingness to exercise are going to gain weight, especially if they’re still eating the number of calories that an active dog would need.
  • Overeating: This one is often on us. We tend to ‘love’ our pups with food and indulge and treat them with calories that they just don’t need.

How to Help Your Dog Lose Weight

1. You need to first access their caloric intake

Unfortunately, it’s not as easy as saying your dog needs X amount of calories per day. Rather, you need to look at their activity level, age, and whether they’ve been spayed or neutered to calculate their caloric needs [2]. Once you know how many calories they need per day, feed them that many. All brands should list the number of calories per cup so you can easily figure out how much food to give.

2. Another option is to look at labels

They will have a recommended feeding guideline for dogs of different weights. These guidelines will be given in a range in order to take different activity levels into account. See where the amount that you’re feeding your dog stacks up to what you should be feeding. Most of us don’t realize that we’re giving our pups more than the recommended amount. You should always measure food and divide it between meals per day rather than free feeding them.

3. Your next option is to feed your dog less of their food

To promote weight loss, you should feed your dog for the weight that they should be at, not the weight they currently are. For example, if your pet weighs 40 pounds (18.14 kg) and needs to weigh 30, feed them the amount that a 30-pound should get, not a 40-pound.

4. Diet is only half of the journey, exercise needs to be included as well

Exercise will promote weight loss more quickly and encourage lean muscle growth. Just like in people, start your dog’s exercise program out slowly and gradually build up to more and more time each day. Look for low impact activities, such as walking or swimming, to help protect those joints.

5. Choose the best options

The real benefit behind these foods is that they will provide complete nutrition with fewer calories so that you don’t have to skimp on meal sizes-something that some dogs just won’t tolerate!

How to Choose the Best Dog Food for Weight Loss

What makes food good for weight loss? Again, weight loss dog foods should be higher than average in protein and lower than average in fat and calories. That way they can still provide the nutrition and energy that dogs need without creating excess fat stores. They are usually higher in fiber as well that acts as a filler to keep a tummy full for longer.

Lower than average calories means you should look for food that’s 400 or fewer calories per cup. Some weight loss foods are actually under 300 calories per cup. Protein levels should be in the high 20s, or better yet, 30 percentages. Fat should be in the single digits percentage-wise.

Besides these nutrition levels, you need to make sure the food you choose is complete and balanced. Look for the AAFCO stamp that ensures that food meets the nutritional requirements for healthy dogs [3]. This will make sure that all needed vitamin and mineral are covered.

An added benefit that you can look for in a weight loss dog food is enrichment with omega fatty acids and glucosamine to aid in joint health and probiotics to help promote healthy digestion. This will just ensure that your dog will maintain overall health while they are traveling down the weight loss road.

Finally, you need to make sure your dog’s weight loss food tastes good. We’re all well aware that human diet foods don’t always taste as great as the alternatives. Diet is the same. Fiber tends to not be tasty, so the higher the fiber the less the taste. Make sure that the brand of weight loss food that you choose is appealing to your pet, or they’re not going to eat it and you’re going to have more troubles on your hands.

Also, make sure that you can afford it. Dog foods for weight loss may be pricier than their regular versions, and your family friend may be on this food for a long time, depending on how much weight they need to loss. Choose a variety that is affordable and easy to get your hands on.
