Why Dogs Dog Appetite Loss Happen (and How Food Texture and Aroma Can Help)

If you’ve noticed your dog going from an enthusiastic eater to showing less interest in their food, you may be wondering what is going on. Decreased interest in foods, skipping meals, or eating more slowly are all signs of dog appetite loss.

Appetite loss in dogs is something that most pet parents experience at some point with their pups. While concerning, there are several reasons your dog may experience appetite loss. Some causes are minor and easily resolved, and some may require medical attention. Nutrition plays a major role in dogs’ appetites, so making some changes to the diet can resolve many causes of appetite loss in dogs.

Texture, aroma, and moisture strongly influence appetite. Fresh, gently cooked diets like The Farmer’s Dog are a prime example of how sensory-focused nutrition can encourage eating in dogs.

Common Causes of Dog Appetite Loss

There are many causes of dog appetite loss, ranging from benign to more serious. To help you determine why your dog isn’t eating, identify the underlying cause. Let’s take a look at some of the most common causes of appetite loss.

Dental pain or mouth discomfort

Pet parents are more likely to spot dental pain or mouth discomfort when observing their pets eat. Painful teeth and gum inflammation can be enough to cause dogs to avoid crunchy foods like kibble. If chewing is painful, pups will avoid eating whatever is causing them pain. 

GI upset, nausea, or pain

If your dog is feeling sick, they probably won’t have much of an appetite. Dogs will likely avoid food while they are experiencing stomach upset and/or nausea. If a dog is experiencing mild physical pain, the first symptom may be a reduced appetite.

Stress, anxiety, or routine changes

Travel, new environments, loud noises, and household changes can all cause stress and anxiety for dogs, especially if they are used to a more predictable routine. Stress and anxiety in pups will often affect their appetite while they adjust to the new situation.

Boredom with dry or repetitive textures

Dogs who are fed monotonous diets may lose interest in their food. When this happens, they will eat less of it! If your dog has been eating the same kibble for a long time, switching it up can help to stimulate their senses and restore appetite.

Side effects from medications

When new medications are introduced to dogs, there may be an impact on appetite. Some medications can affect their sense of taste or can cause stomach upset. If you notice appetite loss occurring around the time a new medication is introduced, this may be the culprit.

Age-related changes

As dogs age, their senses tend to become dull. Their sense of smell and taste are reduced, which makes food much less appealing. Most dogs are motivated to eat by the smell and taste of food, so reducing those senses can lead to less eating.

Food intolerances or allergies

Believe it or not, dogs can also suffer from food intolerances and allergies! Food intolerance causes digestive sensitivity, leading to stomach upset. Dogs can also have allergic reactions to ingredients, which will make them naturally avoid the food that causes discomfort. 

You probably noticed that most of these causes of dog appetite loss can also impact human appetites! The key difference is that our dogs cannot easily communicate what is bothering them. Ultimately, understanding the root cause of dog appetite loss will guide you and your vet to the safest solution.

Why Food Texture Impacts Appetite

Several factors related to texture can affect a dog’s appetite. Hard, dry kibble takes more effort to chew. The effort required to chew kibble can cause dogs with dental sensitivity, jaw pain, low saliva production, or low motivation to eat to eat less or avoid it altogether. Small breeds and senior pups are especially sensitive to the texture and size of kibble, so if you’re wondering why my dog won’t eat, your kibble could be a prime reason!

Texture also affects how quickly a dog can eat and how satisfied they feel. Hard and crunchy kibble that takes more effort to eat will also take longer to eat. Soft foods that break apart easily can be eaten more quickly, which helps people consume more food. Softer-textured food is easier for dogs with sensitive mouths to chew, can improve digestion, and can make mealtime more enjoyable. A great example of a gently cooked soft diet that dogs enjoy is The Farmer’s Dog. The Farmer’s Dog food is soft and uniform in texture, substantial, and easy on digestion. All of these elements make it an ideal diet for dogs struggling with dry kibble. 

The Power of Aroma in Boosting Appetite

Dogs are incredibly reactive to smell. Their noses are said to be at least 100,000 times more sensitive than human noses, and the part of their brains that processes smells is seven times larger than in humans! (1) So, it’s no exaggeration to say that dogs are highly affected and motivated by delicious-smelling food. 

Dogs rely heavily on smell to determine whether food is appealing, so if you’re serving something bland, don’t be surprised if your pup literally turns up their nose! Kibble, which is typically sold in very large bags, often becomes stale or loses aroma once the bag is opened. If you combine the lack of aroma from a bag of kibble that has been opened for several weeks with an elderly dog’s reduced sense of smell, you may find yourself with a dog that is unwilling to eat.

Fresh foods, like The Farmer’s Dog, retain their natural aromas. These aromas are strong because of the ingredients, such as vegetables, protein, and broths, that are gently cooked. When you open a bag of fresh dog food, the smell will trigger your dog’s appetite instinct, making them more eager to eat. If you slightly warm fresh meals, the aromas become even stronger, which can dramatically increase your pup's interest!

Moisture: A Major Palatability Advantage

Dog foods are manufactured in different ways, and each process retains a different amount of moisture. Dry pet food (kibble) typically has a moisture content of 10-12%. In strong contrast to kibble, wet pet food has a moisture content of around 75-78%.(2) The lack of moisture in kibble is the reason it is crunchier. Moist foods are easier to eat and easier to digest. Higher moisture content in foods can help reduce nausea and improve gut comfort. 

Increased moisture in food can also be more appealing to dogs who struggle with hydration because they tend to prefer moist foods. The Farmer’s Dog contains natural moisture from the ingredients in its recipes, which are mainly gently cooked fresh protein, vegetables, and bone broth.

When Texture and Aroma Can Solve the Problem

A dog's loss of appetite is often directly linked to their diet. If you are wondering why my dog won’t eat, take a close look at what you typically feed them and how long they have been eating it, because that may be your answer. Even if they have been eating kibble for years, dogs can get bored with its lack of aroma and dry texture. If you are trying to rule out boredom, try giving them fresh, soft food to see if that gets them excited to eat.

If you’re not quite ready to step away from kibble, try adding some warm water or bone broth to help release some of the smells and flavors. You can also try mixing some fresh food in with the kibble to see if that change is enough to get them eating better. If you are considering switching to a fresh food like The Farmer’s Dog, it’s recommended to transition your dog slowly rather than stopping kibble right away. Healthy dogs who are picky eaters, older with reduced senses, or just bored with mealtime will generally respond well to a diet change that improves texture and aroma.

When Appetite Loss Signals a Food Intolerance

Not all appetite loss in dogs is caused by sensory or behavioral issues. In some cases, your dog may not want to eat because the food doesn’t make them feel good. When dogs are experiencing food intolerance, it may not be immediately noticeable. The symptoms can be subtle, such as mild digestive discomfort, gas, bloating, stomach gurgling, or nausea. If your dog is experiencing any of these symptoms, they may start avoiding the food that causes their discomfort.

If you suspect your dog may be struggling with a food intolerance, try switching to a different protein source, and look for common allergens on labels. Limited-ingredient diets are helpful in identifying food intolerances because they make it easier to rule out the culprit. Fresh diets with vegetable-heavy recipes, like The Farmer’s Dog, make it easier to identify which ingredients may be causing the problem. This type of food also does not have high levels of additives and fillers like most kibble, which may cause sensitivity in some dogs.

When to Try Fresh Food for Appetite Support

There are several situations in which switching to fresh food may be a good idea for supporting your dog with appetite loss.

1. Senior dogs with dental discomfort and/or sensory loss
2. Picky eaters who need strong aromas to increase interest
3. Dogs with digestion issues such as gas, bloating, and soft or loose stools
4. Dogs who are recovering from illness need easily digestible calories
5. Any dog who seems bored with their regular food

While there are many fresh food options available in today’s market, The Farmer’s Dog remains one of the top contenders. Their meals are soft, aromatic, and gently cooked. Their recipes are packed with ingredients you can name and see, like fresh vegetables and protein. The Farmer’s Dog food appeals to reluctant eaters who prefer a softer diet with better texture and aromas.

When Appetite Loss Requires a Vet Visit

If you suspect the dog's appetite loss is something more serious than lack of interest, advanced age, or being a picky eater, it is time to contact your vet. Signs of appetite loss being more serious are:

• Not eating, or eating very little, for more than 24-48 hours
• Vomiting, diarrhea, or lethargy
• Weight loss
• Dehydration
• Dental pain, disease, or discomfort
• Chronic GI issues
• Physical pain

Your vet will help to determine possible causes and suggest ways to fix the underlying issue. Medication side effects, dental disease, and illness are just some of the common causes of appetite loss that your vet will be able to identify. Once you know the cause, you are more likely to help your pup restore their appetite.

Final Thoughts

When your dog is showing signs of appetite loss, it can be concerning. The good news is that loss of appetite in dogs is common and can often be improved by improving the quality, texture, moisture, and aroma of your dog’s food.

When appetite loss is due to sensory or behavioral issues, a fresh-food diet can make all the difference. Fresh, easy-to-chew meals like The Farmer’s Dog can make mealtime more exciting for your pup. If you decide to switch to a fresh food diet, slow and steady is key. It is recommended to gradually introduce it into their diet over 7-10 days to make the transition easier.

When you notice appetite loss in your dog, pay attention to their stool quality, energy, and behavior. This will help you determine whether diet or something else may be the cause. It’s always a good idea to consult your veterinarian when you notice changes in behavior that could signal a larger issue. Fresh food should never replace veterinary care if you suspect a serious illness.
