Why Do Senior Dogs Stop Eating and What You Can Do

Senior dogs stop eating for a variety of reasons, and it's essential to identify the cause to provide the right care.

Loss of appetite in older dogs can be a sign of dental problems, with gum disease affecting up to 80% of dogs over the age of three.

As dogs age, their sense of smell also declines, which can make food less appealing.

Dental issues are often accompanied by bad breath, which can be a clear indication that your senior dog needs a dental checkup.

Some senior dogs may develop a condition called megaesophagus, where the esophagus becomes enlarged and food gets stuck.

This condition can lead to weight loss and poor appetite, making it crucial to work with your veterinarian to manage the symptoms.

Physical problems can be a major reason why older dogs stop eating. Many older dogs won't eat well if they have chronic health problems, such as cardiac, renal, or hepatic disease.

Dental disease can also be a culprit, making it painful for your dog to eat. A dog with a sore mouth may approach food, but then walk away.

Nausea and intestinal blockages are other potential issues. If your dog has ingested a toxin or is experiencing vomiting, diarrhea, or drooling, it's a good idea to seek veterinary attention.

If your dog hasn't eaten in 24 hours, contact your veterinarian. Your vet will likely run bloodwork to identify any worsening or developing problems.

Some signs that might indicate a physical problem include:

A thorough physical examination is also important. Your vet may notice a sore neck or other issues that could be affecting your dog's appetite.

Medical conditions can be a major reason why old dogs stop eating. Infections and cardiovascular diseases can cause a reduction in appetite, while gastrointestinal diseases can make eating painful.

If your dog has a tooth or gum injury, it may be uncomfortable for them to eat, leading to a refusal of food. This is especially true if the injury is severe.

Senior dogs are more prone to underlying illnesses that can cause a loss of appetite. These illnesses can be anything from kidney disease to heart disease to cancer.

It's essential to have your dog examined by a vet to determine the cause of their lack of appetite and find the best course of treatment.

As dogs age, their bodies undergo significant changes that can affect their eating habits. Their sense of smell and taste decreases, which may change their food preferences or decrease the excitement they experience at mealtime.

Older dogs may not expend as much energy since they exercise and move around less, which may explain why they aren't as hungry as they used to be. This can be a normal part of aging, but it's essential to monitor their weight and body condition to ensure they're not losing too much weight.

Most senior dog foods are formulated with appropriate nutrient limits and are less calorie-dense than rations for puppies and young adults. However, some products may have protein calorie levels similar to growth diets.

Here are some key principles for feeding a senior dog:

Eating 20% to 25% fewer calories has been shown in adult dogs to slow the progression of age-related changes and increase a dog's lifespan. However, in very old dogs, it may be more important to increase their caloric and protein intake to sustain a normal physique as their body condition and weight naturally decline with advanced age.

Old dogs can be finicky, but a loss of appetite in dogs is often a sign of something more serious. If your senior dog is refusing to eat, it's essential to investigate the underlying cause.

Adding warm water or salt-free broth to their kibble can make it more enticing and aromatic, but this is only a temporary solution. If your dog's appetite hasn't returned to normal, it's time to see a veterinarian.

There are several common causes of reduced appetite in dogs, including illness, dental disease, recent vaccination, travel and unfamiliar surroundings, and pickiness or behavior issues. Prompt veterinary attention is crucial, especially if your dog is exhibiting other symptoms.

A decreased appetite in dogs can be a sign of significant illness, including cancer, systemic infections, pain, liver problems, and kidney failure. Your veterinarian can help determine the underlying cause and recommend the best course of action.

Some dogs may refuse to eat due to dental disease, which can cause pain and discomfort. Have your dog checked for a broken or loose tooth, severe gingivitis, and even an oral tumor.

Here are some potential reasons why your old dog may not be eating:

In some cases, a loss of appetite in dogs can be caused by something as simple as traveling or moving to a new location. However, it's essential to investigate other possibilities before assuming your dog is just picky.

As we explore why old dogs stop eating, it's essential to consider the external factors that may be at play.

Changes in a dog's environment can significantly impact their appetite. For instance, a move to a new home can be stressful for dogs, leading to a decrease in appetite.

External factors can also include changes in a dog's social circle. If a dog's primary caregiver is away for extended periods, the dog may lose interest in food due to separation anxiety.

Other external factors to consider are changes in a dog's physical environment, such as a new pet in the house or a change in the dog's living space.

If you've recently changed your dog's food or feeding time, it could be affecting their appetite. Two days is the most time your dog should go without eating before seeking medical attention.

Changing your dog's environment, such as returning from a trip or moving houses, can also cause stress and impact their appetite.

Consult a veterinarian as soon as you have concerns about your pup, and never punish them for not eating.

Medication Side Effects can be a common reason why old dogs stop eating. New medications can make dogs lose their appetites.

Some medications have nausea as a side effect, which can lead to a decrease in appetite. A new prescription diet might be to blame, too - they aren't always the tastiest.

Consult with your vet about next steps if you think medication side effects are the cause. Maybe you can switch to another medication or prescribed diet.
