A change in a dog’s eating habits, either up or down, is a clue that something is not right with your dog. When a dog refuses to eat out of the blue, he is telling you that he doesn’t feel well, either physically, mentally, or emotionally. There are many things that affect a dog’s appetite, such as dental disease, undiagnosed pain, stress and anxiety, upset stomach, infectious disease such as worms or influenza, or cognitive dysfunction.

In humans, we know that taste decreases with age, and humans on cancer treatment say that nothing tastes good. The same may be true for our canine companions. When your dog doesn’t eat, it is important to visit your veterinarian to figure out what isn’t right, and fix it. If it is going to take some time to resolve the underlying issue, then an appetite stimulant may be indicated to support your dog on the road to recovery. 


A dog is truly man’s best friend, closest confidant, and giver of unconditional love and support. Your canine companion is a member of your family, and when they don’t feel well, it’s important to identify and treat the problem. Just like humans, dogs may fall victim to a decrease in appetite or become disinterested in their food. While a day or two of this activity may not be cause for concern, prolonged issues with eating or appetite can lead to serious consequences. Luckily, below are several ways that you can stimulate your furry friend’s appetite and get them back on the road to healthy eating.

Features of Appetite Stimulant For Dogs

Anabolic steroids are synthetic derivatives of testosterone that have enhanced anabolic effects with reduced androgenic effects. Anabolic steroids do not directly affect hunger, satiety, or sensory perception of food. Instead, they antagonize the catabolic effect of glucocorticoids and the negative nitrogen balance associated with surgery, illness, trauma, and aging. In all cases, improved nitrogen balance depends on adequate protein/calorie intake and treatment of the underlying disease. Anabolic steroids stimulate hematopoiesis, appetite, and weight gain. Adverse effects of anabolic steroid therapy include hepatotoxicity, masculinization, and early closure of bony epiphyses in young animals. Anabolic steroids are contraindicated in animals with congestive heart failure because of sodium and water retention. Because of human abuse potential, anabolic steroids are controlled substances. Although once (in)famous for abuse in people and horses, stanozolol and boldenone undecylenate are no longer marketed by veterinary pharmaceutical companies in North America. Currently, any anabolic product for veterinary use can only be obtained from a compounding pharmacy.

Mirtazapine was created to treat depression in humans, but was found to be very beneficial in stimulating appetite in pets. It is usually administered to pets suffering from conditions like renal failure and stomach disease. In addition, it aids with loss of appetite or nausea associated with cancer treatments. Mirtazapine is sold per tablet and requires a prescription from your veterinarian.

Why do dogs lose their appetite

When appetite starts to fall, it is often due to a disease or condition such as:

  • Cancer
  • Kidney disease or liver disease
  • Gastrointestinal (GI) disease (including pancreatitis in dogs)
  • Inflammatory bowel disease (IBD)
  • Pain
  • Surgical recovery
  • Dental disease in dogs
  • Tooth root abscess in dogs

Potential Side-Effects of Mirtazapine

Mirtazapine generally is well tolerated in dogs and cats, although trials are lacking. Common side- effects include drowsiness, sedation, low blood pressure, and increased heart rate. If the animal experiences breathing difficulties, hives or swelling of the lips, tongue, or face, then an allergic reaction to the drug can be the case. The most-common side effects in humans are somnolence, dry mouth, increased appetite, and weight gain.


Dog supplements to stimulate appetite are effective for the right dog and circumstance. This means they may not work for your dog and some of the methods may be more effective than others. It depends partly on the underlying cause of your dog’s resistance to eating, and the treatment’s benefit alongside how common of a problem it is. Does the treatment temporarily stop the problem? Will the treatment be ongoing? How many satisfactory reviews has this method or treatment received? These are all important questions to ask before purchasing a product.

For example, if a new dog is feeling anxiety or a lack of appetite from just moving in, providing them with some rotisserie chicken as a treat or on top of meals can encourage them to develop an eating habit. Whereas an acupuncture treatment would not be suitable in this scenario and may make things worse.

Precautions for Using Mirtazapine

Mirtazapine should not be prescribed or administered to a patient that is hypersensitive or allergic to the medication. It also should be used with caution whenever the animal is taking other medications, as it can interact with other drugs, including Tramadol and monoamine oxidase inhibitors.
