A dog’s eating habits can be a crucial indicator of their overall well-being. When your dog suddenly refuses to eat, it’s a clear sign that something might be amiss, whether it’s a physical ailment, a mental struggle, or an emotional disturbance. A dog refusing to eat without a clear reason warrants attention.
Numerous factors can influence a dog’s appetite. These can range from common issues like dental disease and undiagnosed pain to more complex concerns such as stress and anxiety, gastrointestinal upset, parasitic infections like roundworms, or infectious diseases like influenza. Cognitive decline, often referred to as cognitive dysfunction, can also play a role.
When your dog’s appetite wanes, a visit to your veterinarian is essential for a thorough examination. Identifying the root cause of the anorexia is the first step toward restoring their desire to eat. In some cases, and depending on the diagnosis and treatment plan, your vet might suggest an appetite stimulant to aid in your dog’s recovery process.
What Are Appetite Stimulants for Dogs?
Appetite stimulants are substances or methods designed to encourage a dog to eat more or to induce feelings of hunger. While it’s paramount to address the underlying cause of the decreased appetite, appetite stimulants can be a valuable component of the overall treatment strategy.
When Do Dogs Need Appetite Stimulants?
Appetite stimulants may be recommended in several scenarios:
- When a dog consistently refuses to eat for a period that begins to negatively affect their health.
- When a dog is not consuming sufficient calories to maintain a healthy body weight.
- When a dog is undergoing treatment with medications, such as chemotherapy, which are known to decrease appetite.
- When a dog is in the recovery phase after an illness or surgery and requires additional nutritional support to regain their appetite.
Veterinarian-Recommended Appetite Stimulants for Dogs
1. Specially Prepared Treats and Food Toppers
One effective approach to stimulating a dog’s appetite is by offering their favorite treats or preparing a special meal. Simple options like plain, boiled chicken can be highly enticing for a sick or older dog with a finicky appetite. Ensure that any chicken given to your dog is unseasoned, skinless, and boneless. Giving your dog chicken should always be done with their health in mind.
Incorporating food toppers, such as warmed broths or wet food, can also encourage dogs to finish their meals. Switching from dry kibble to canned food is another simple strategy that can often improve a dog’s interest in eating.
Other methods to encourage eating include hand-feeding to coax your dog, or gently warming their food. Warming food can enhance its aroma, making it more appealing. However, it’s crucial to exercise extreme caution when microwaving dog food. Food can heat unevenly, creating dangerously hot spots. Heat it in very short intervals and always test the temperature with your hand before serving it to your pet.
2. Acupuncture
While acupuncture is not a cure for underlying conditions, it has shown efficacy in reducing pain, inflammation, and nausea. Dogs suffering from decreased appetites due to medical conditions such as diabetes, kidney or liver failure, pancreatitis, or hormonal imbalances like Addison’s disease, often experience an improved appetite following acupuncture sessions.
3. Mirtazapine
For decreased appetite stemming from a medical condition, your veterinarian may prescribe medication. Mirtazapine is frequently prescribed to dogs experiencing appetite loss due to conditions causing queasiness, such as kidney disease or cancer, or as a side effect of treatments like chemotherapy.
Originally developed as an antidepressant for humans, Mirtazapine’s known side effects of weight gain and increased appetite led to its use in veterinary medicine as an appetite stimulant for dogs.
4. Maropitant (Cerenia®)
While not directly classified as an appetite stimulant, Maropitant (Cerenia®) is a potent anti-nausea medication that can indirectly help improve a dog’s appetite. Often, dogs refusing food are experiencing nausea, even without overt vomiting. Anti-nausea medications can be highly beneficial in promoting consistent eating. Other anti-nausea drugs your vet might consider include ondansetron and meclizine.
5. Entyce® (Capromorelin)
Entyce® functions as a ghrelin receptor agonist. By mimicking the action of ghrelin, the “hunger hormone,” it stimulates the production of growth hormone signaling to the brain, thereby increasing the sensation of hunger in dogs.
Can CBD Help a Dog’s Appetite?
Before administering CBD to your dog for appetite support, it is crucial to consult with your veterinarian. According to The American Veterinary Medical Association (AVMA), there is currently insufficient scientific evidence to confirm CBD’s effectiveness in enhancing a dog’s appetite. It’s likely that more established and proven appetite stimulants would be a better choice for your dog.
When to Seek Veterinary Care
It can be incredibly distressing when your dog refuses to eat. Anorexia in dogs can stem from a wide array of causes, from simple pickiness to serious underlying medical conditions.
As a general guideline, if your otherwise healthy adult dog has not eaten for more than two consecutive days, it is advisable to contact your veterinarian. If your dog exhibits additional symptoms alongside appetite loss—such as vomiting, lethargy, or diarrhea—you should reach out to your vet immediately.
Similarly, for very young puppies, senior dogs, or dogs with pre-existing health issues like diabetes, even missing a single meal can be significant. In these cases, it’s important to contact your vet promptly to discuss the situation.
Your veterinarian will likely recommend a physical examination to identify any apparent causes, such as dental problems or abdominal pain. Further diagnostic tests, such as blood work or X-rays, may be ordered to gain a clearer understanding of the issue and determine the most appropriate course of treatment. Appetite stimulants may then be incorporated into the treatment plan as needed.
