Old Dog Eating A Lot But Losing Weight

While it’s not uncommon for dogs to lose a few pounds once in a while, any sudden and unexplained weight loss is a huge red flag for all dog owners. If your dog is losing weight but eating, a visit to your veterinarian is in order.

Like people, dogs can lose weight for many reasons. Rapid weight loss can be a sign of serious underlying health conditions. But it may also be that your dog is more active and burning more calories than before.

Weight loss that exceeds more than 10% of your dog’s normal body weight is a cause for serious concern and warrants a trip to your veterinarian.

Weight Loss In Older Dogs: Is It A Problem? What You Need To Know

Anything less than 10% isn’t considered clinically significant, but you should keep a close eye on your pooch and monitor their weight.

Keep on reading to find out the most common causes for sudden weight loss in dogs and what you can do about it.

It’s completely normal for your dog’s weight to change over the course of its lifetime. Factors such as diet, age, breed, and health problems can affect your dog’s weight and cause weight loss. However, if you have detected that your dog is eating well but still losing weight, then speak with your veterinarian as soon as possible.

How Much And How Often To Feed Your Dog

While dogs can lose weight for many different reasons, getting slimmer is never normal unless your dog is on a planned diet. If your pooch lost a lot of weight suddenly, despite having a healthy appetite, don’t panic! Instead, take your dog to the veterinarian so they can identify the problem and offer your pup the necessary treatment.

Not all cases of weight loss in dogs are caused by diseases. You may be surprised to learn that changing your dog’s food is one of the most common causes of weight loss.

You may think, this can’t be the case since I haven’t changed my dog’s food in years. However, while your dog may be eating the same brand of kibble, it doesn’t mean that the manufacturer didn’t change the formula in the meantime.

How To Help Your Dog Lose Weight & Keep It Off

Not suspecting a thing, you continue feeding your pup the same amount of dog food as before, but alas the new formula has 10% fewer calories. At the end of the day, your dog ends up eating fewer calories than it needs and, as a result, starts losing weight sooner or later.

These changes are easy to miss since many dog foods are labeled in a very confusing way. So, before you jump to the conclusion that your pup is sick, check the food’s ingredient label and see how many calories it has per serving.

If the food is the same as before, schedule an appointment with your veterinarian. But, if it turns out that the formula was changed and has fewer calories, simply start feeding your dog more of it.

Reasons Why Your Dog Is Overweight (even If They Don't Eat Much)

While most dog owners stay up-to-date with monthly deworming treatments, which offer protection against intestinal parasites and heartworms, , there are many different types of intestinal parasites, and not all deworming treatments are equally effective. For example, many treatments can’t kill whipworms, but your dog can get infected by ingesting the eggs from contaminated water or soil.

The main issue with intestinal parasites is that they consume all the food the dog eats, thus depriving it of all necessary nutrients. Intestinal parasites may be to blame if your dog is eating a lot but losing weight.

Luckily, intestinal parasites are easy to diagnose through a fecal exam and are treated by a broad-spectrum dewormer. After a successful treatment, a monthly deworming medicine is the best preventative.

How To Fatten Up A Dog: 7 Easy Tips To Get Your Dog Eating Asap

Unfortunately, diabetes is often diagnosed in older dogs, especially in females. Dogs with diabetes start losing weight rapidly since their bodies can’t get the energy from the glucose and instead try to convert fat or protein into energy.

If your older dog is losing weight but eating and is also drinking a lot of water, you should take them to your veterinarian. Most dogs with diabetes lose weight very quickly and may also start to lose muscle mass.

And since diabetes causes excessive thirst, your dog will also have to urinate excessively and may have accidents in the house even if properly housetrained.

Best Senior Dog Food, According To A Veterinarian

If your dog is experiencing any of these symptoms, it’s important to take them to the vet right away. Your veterinarian will run blood glucose tests and a urinalysis to determine whether your dog has diabetes. When the diagnosis of diabetes is confirmed, the treatment will include insulin shots and a specialized diet.

Maldigestion disorders, such as exocrine pancreatic insufficiency, hamper the body’s ability to break down food into usable nutrients. This means that all essential nutrients your dog eats every day just pass through their digestive system without being absorbed by the body.

A dog with a maldigestion disorder will have a healthy appetite but will continue to lose weight. Besides the notable weight loss, your pooch may also have diarrhea, loose yellow stool, and gas. However, these symptoms alone aren’t enough to diagnose the problem.

Why Is My Senior Dog Losing Weight?

Therefore, you will need to take your dog to the veterinarian who will perform a full physical exam and run tests. Your veterinarian will most likely take a stool sample and test your dog’s blood for digestive enzymes.

Malabsorption disorders interfere with the body’s ability to absorb nutrients from the intestinal tract. Inflammatory bowel disease is one of the most common malabsorption disorders diagnosed in dogs.

If your dog is eating a lot but losing weight and also vomits, has diarrhea, or foul-smelling loose stool, they may have inflammatory bowel syndrome. The exact cause of this disease isn’t completely understood, but it leads to inflammation of the intestines.

What To Do If Your Senior Dog Is Not Eating

The initial testing for inflammatory bowel disease includes fecal examination, blood testing, and an X-ray or ultrasound of the intestines. There is no cure for this disease, and treatment consists of a specialized diet, probiotics, and anti-inflammatory drugs. While inflammatory bowel disease is a chronic condition, your dog can lead a normal life with a change of diet and appropriate treatment.

Dental disease is a common problem for many dogs, especially seniors. Broken or infected teeth, gingivitis, or gum disease can be extremely painful and make it hard for your dog to properly eat food.

Since dental problems make chewing very painful, many dogs stop eating their food and start losing weight. However, dogs who aren’t experiencing severe oral pain may continue eating but still lose weight because they are unable to chew properly.

Overweight And Dog Weight Loss Plan

If your dog is losing weight and has any of these symptoms, take them to the veterinarian for a dental exam. Bear in mind, if dental disease isn’t diagnosed and treated in time, oral bacteria can spread throughout your dog’s body and affect the heart, liver, or kidneys.

When spotted in time, dental disease is fairly easy to treat and most dogs start eating normally once the issue is resolved. Since dental problems can have big repercussions for your dog’s overall health, you should be proactive and start brushing your dog’s teeth from a young age.

As your dog gets older, its organs can’t work as effectively as before. While weight loss can be a symptom of many conditions, dogs with kidney disease don’t start losing weight immediately. Instead, weight loss is typically associated with advanced forms of kidney disease.

Why Your Older Dog Is Losing Weight And What To Do

Dogs can experience acute and chronic kidney failure. With the latter, the disease progresses slowly over the years and is usually diagnosed in older dogs. Chronic kidney disease is caused by an underlying illness, hereditary conditions, and dental disease.

Since kidney failure is a life-threatening condition, it is essential that you take your dog to the veterinarian if you notice any of these symptoms. The treatment for kidney failure depends on the severity of your dog’s symptoms and whether the condition is acute or chronic.

Liver disease is a common condition in dogs and another potential cause of your dog’s weight loss. Since liver disease has similar symptoms to those of other health problems, many owners don’t realize that something is wrong until it’s too late.

In most cases, liver disease is the result of aging, but it can also be genetic or caused by an infection, fatty food, or certain plants and medications. Besides weight loss, dogs with liver problems can also exhibit the following symptoms:

While liver disease is often seen in older dogs, young dogs can have it, too. If your dog is losing weight and experiencing any of these symptoms, take them to the veterinarian as soon as possible. Your dog’s treatment will depend on the severity of liver damage and the problem that caused it.

Like with kidney disease, dogs with heart problems don’t start losing weight right away. In fact, early symptoms of heart disease in older dogs are so subtle that most owners ascribe them to the normal age-related slowing down.

How To Help Your Dog Lose Weight

Since heart disease can lead to congestive heart failure, it’s important that you know the symptoms so you can get your dog the help they need.

Heart disease is a serious condition, so it’s crucial that you take your dog to the veterinarian as soon as you notice any of these symptoms. When diagnosed in
