Common Reasons Why Dogs Stop Eating

There are numerous reasons why your dog might turn their nose up at their food. These can range from simple pickiness to underlying health issues. A sudden change in your dog’s eating habits is often a red flag that something is amiss, whether it’s related to their physical health, emotional state, or even the food itself. If you observe a decrease in your dog’s appetite without an obvious cause like spoiled food, it’s always wise to consult with your veterinarian.

When to Worry: My Dog Won’t Eat or Drink

If your dog is not only refusing food but also water, this is a serious situation requiring immediate attention. Dehydration can quickly become dangerous for dogs. Encourage your dog to drink by ensuring their water bowl is clean and filled with fresh, cool water. You can try adding a small amount of tuna juice (from tuna in water, not brine or oil) to their water to make it more appealing. Alternatively, offer them ice cubes to lick or chew, or the cooled water from poaching chicken (avoid using salty stock cubes). If your dog still refuses to drink, contact your vet immediately.

Medical Reasons for Loss of Appetite in Dogs

A lack of appetite, especially if sudden, can be an early indicator of illness in dogs. Many health conditions can cause a dog to stop eating, ranging from minor issues like dental pain or a mild stomach upset to more serious conditions such as pancreatitis or even cancer. Potential medical causes include:

  • Oral Pain: Dental problems such as tooth decay, infections, gum disease, or broken teeth can make eating painful and deter your dog from food.
  • Gastrointestinal Issues: Stomach problems, intestinal issues, or tummy upsets can stem from viral or bacterial infections, inflammation, intestinal blockages, parasitic worms, or overeating. Dietary indiscretion, like scavenging for inappropriate items during walks, or sudden changes in diet are common culprits for digestive upset.
  • Pain: Dogs are adept at hiding pain, but it can significantly impact their appetite. Pain from any source can lead to reduced food intake.
  • Organ Dysfunction: Problems affecting vital organs such as the heart, lungs, liver, pancreas, or kidneys can cause nausea and general malaise, leading to a decrease in appetite.
  • Systemic Illness: Infections or viral illnesses can make dogs feel generally unwell, mirroring human experiences of reduced appetite during sickness.
  • Medication Side Effects: While less common, certain medications can have side effects that include nausea and appetite suppression. Always discuss potential side effects with your veterinarian when your dog is prescribed medication.

Behavioral and Emotional Reasons for Appetite Loss

Dogs are sensitive creatures, and their emotional state can significantly influence their eating habits. Anxiety, stress, or fear can all contribute to a dog’s refusal to eat. Dogs thrive on routine, and even minor disruptions to their environment or daily schedule can be stressful and affect their appetite. Behavioral reasons could include:

  • Environmental Changes: New environments, home renovations, moving houses, loud noises like fireworks or storms, or the introduction of new pets can all trigger stress and appetite loss.
  • Routine Disruptions: Changes in the daily routine, such as the loss of a family member or pet, changes in work schedules, or children returning to school, can create anxiety and impact eating habits.
  • Separation Anxiety: Dogs with separation anxiety may refuse to eat when left alone for extended periods, or when their owners are away, such as during work hours or vacations. Some dogs may only eat when their owners are present.

Typically, if stress or anxiety is the cause, a dog’s normal eating patterns should resume once the stressor is removed or they adapt to the change. However, some dogs may need additional support to manage anxiety. Consulting your veterinarian or a certified dog behaviorist can provide strategies to help your dog cope.

Is Your Dog a Fussy Eater?

If your dog rejects their regular food but eagerly accepts treats or human food, they might simply be a picky eater. Picky eating is often a learned behavior. Smart dogs may realize that by refusing their usual meals, they are more likely to receive more appealing alternatives or extra attention from their owners. This can reinforce picky eating habits. Neophilia, a preference for new tastes, can also contribute to fussiness if dogs are constantly offered a variety of foods. They might eat enthusiastically at first but then become bored as the food becomes familiar.

The Impact of Overfeeding and Treats

Overfeeding, particularly with treats and snacks, can significantly reduce a dog’s appetite for their main meals. Treats should only constitute a small percentage (ideally no more than 10%) of a dog’s daily caloric intake. Excessive treats can lead to an unbalanced diet, weight gain, and various health problems. Ensure all family members are aware of feeding guidelines and avoid over-treating your dog.

Problems with the Dog Food Itself

Sometimes, the issue is simply with the food itself. Consider these food-related factors:

  • Stale or Old Food: Food that is old or stale loses its palatability. Always offer fresh food. Store dry food in airtight containers and refrigerate opened cans or pouches, using them within 24 hours.
  • Expired Food: Check expiration dates and discard any food past its “best by” or “sell by” date.
  • Spoiled Food: Food can spoil even before the expiration date if not stored properly. Store food in a cool, dry place. Once opened, dry food should ideally be used within a month. Buy appropriately sized bags to ensure freshness.
  • Changes in Food Formula: A “new and improved” formula might not appeal to your dog. Introduce new foods gradually over 7-10 days to allow your dog to adjust to the taste and avoid digestive upset.

Strategies to Encourage a Dog to Eat

If your dog is not eating, try these methods to stimulate their appetite:

  • Offer Small Portions: Provide smaller, more frequent meals instead of large portions.
  • Warm the Food: Gently warming food to body temperature can enhance its aroma and make it more enticing. Ensure the food is thoroughly stirred to eliminate hot spots.
  • Hand Feeding: For some dogs, hand-feeding can be more appealing and encourage them to eat.
  • Probiotics: Consider adding a probiotic supplement like Pro Plan FortiFlora, which can improve gut health and palatability. Consult your vet before adding supplements.

Making Dog Food More Enticing

Enhance the appeal of your dog’s food with these simple additions:

  • Soften Dry Food: Add a little lukewarm water to kibble and let it soak for a few minutes to soften it and release aromas.
  • Warm Wet Food: Gently warm canned food in the microwave to body temperature to intensify its smell and palatability. Always stir and test the temperature to avoid burns.
  • Add Cooked Chicken: Mix small amounts of plain, boneless, skinless cooked chicken into their regular food to make it more appealing.

Never Force-Feed a Dog

Do not force-feed a dog that is refusing to eat. This can create negative associations with food and potentially cause aspiration. Instead, focus on making food more appealing and consult your veterinarian if the issue persists.

When to Seek Veterinary Advice for a Dog Not Eating

Consult your veterinarian if your dog:

  • Has not eaten for 24 hours.
  • Has not eaten for 12 hours and is also vomiting or has diarrhea.
  • Is refusing both food and water.
  • Is losing weight.
  • Appears unusually lethargic or tired.
  • Shows other signs of illness, such as coughing, constipation, or straining to defecate.
  • Exhibits signs of dental problems, such as mouth pain, bleeding gums, excessive drooling, or pawing at their mouth.

Understanding Stomach Gurgling and Appetite Loss

If your dog’s stomach is gurgling but they are not eating, this could indicate gastrointestinal upset. The gurgling sounds are caused by gas moving through the digestive tract. If your dog is unwell or has not eaten for a day, veterinary consultation is recommended.

Dog Eats Treats But Not Regular Food

If your dog eats treats but refuses their regular food, it might be due to pickiness or simply holding out for something more appealing. However, it could also be a sign of underlying illness, as even sick dogs might accept treats when they refuse meals. If there is a sudden change in appetite, consult your veterinarian. If you suspect pickiness, explore strategies for managing fussy eaters.

Refusal to Eat Dry Food

A sudden aversion to dry food can indicate dental pain or gum issues. Dogs feeling unwell may also prefer wet food because of its stronger aroma and softer texture. Try softening dry food with warm water or mixing in a small amount of wet food. If your dog consistently refuses dry food, veterinary examination is advised.

Eating from Hand But Not from Bowl

If your dog eats from your hand but not their bowl, the bowl itself or its location might be the problem. The bowl could be in a noisy or busy area, difficult to eat from if it slides, or your dog simply might not be hungry or dislike the food. Hand-feeding is often more engaging for dogs. Try using a different bowl, eliminating treats, or mixing in a different food to see if eating habits change. Rule out dental pain if these methods are ineffective.

Dog Not Eating But Acting Normally

If your dog is not eating but otherwise seems healthy and energetic, try encouraging them to eat. If they still refuse food after a day, consult your veterinarian. While there can be benign reasons for temporary appetite loss, persistent lack of appetite warrants veterinary investigation.

Pregnant Dog Not Eating

Pregnant dogs, especially in early and late pregnancy, may experience appetite fluctuations. Offer small, frequent meals of highly palatable food. In late pregnancy, a growth-type diet is beneficial due to its higher calorie and nutrient density. If a pregnant dog refuses food for 24 hours or is losing weight, seek veterinary advice.

New Dog Not Eating

Newly rescued dogs may be too stressed or anxious to eat initially in a new environment. Allow them time to adjust and offer familiar food in a quiet, calm setting without interruptions. Appetite should return within a day or two as they settle in.

Sick Dog Not Eating

For a sick dog, short-term appetite loss is common. Bland diets like boiled chicken and white rice can be offered in small amounts to settle the stomach, but these are not nutritionally complete for long-term feeding. Veterinarian-prescribed gastrointestinal diets are more balanced and digestible, containing prebiotics to aid recovery. Offer small, frequent meals. If your sick dog is not eating and has vomiting or diarrhea, veterinary consultation is essential.

Stressed Dog Not Eating

For stressed dogs, feed them in a calm, comfortable location with reassurance. Offer favorite foods to encourage eating. Loud noises like fireworks or thunderstorms can suppress appetite. Even if a stressed dog won’t eat, ensure they have access to fresh water, as panting due to stress can lead to dehydration.

Older Dog Not Eating

Appetite changes in senior dogs can be due to various age-related factors, including illness, dental pain, vision loss, arthritis pain, or cognitive decline (canine dementia). Reduced sense of smell can also make food less appealing. Establish a consistent feeding routine, avoid moving food bowls, and provide non-slip surfaces for eating, especially for dogs with arthritis. If an older dog hasn’t eaten for a day, is losing weight, or shows concerning changes in eating habits, consult your veterinarian.

Puppy Not Eating

Puppies adjusting to new homes can be nervous and may initially eat less. Regular feeding is crucial for puppies. If a puppy has not eaten for 12 hours or shows signs of illness, veterinary consultation is necessary.
