6 Appetite Stimulants for Dogs
By Sarah Wooten, DVM
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.
When Can Appetite Stimulants Help My Dog?
Appetite stimulants are indicated when a dog refuses to eat long enough that it impacts his health, consistently does not consume enough calories to support a healthy weight, is on a medication (such as chemotherapy) that decreases appetite, is recovering from an illness and needs appetite support, or to help a dog eat a new diet. Dogs with kidney disease, for example, can have underactive appetites that lead to weight loss, or may not want to eat their therapeutic kidney diet. An appetite stimulant can help in this case to get the dog the nutritional support that he needs. There are several options that your veterinarian can suggest, including pharmaceutical, natural, and holistic options.
Ways to Stimulate Your Dog’s Appetite
For a sick, debilitated, or geriatric dog who is picky about eating, one of the easiest (and cheapest) options to try is tempting him to eat rotisserie chicken. We all know how good rotisserie chicken smells in the grocery store when we walk by—and it smells even better to dogs. Even the pickiest eater will often gobble up his food if you doctor it up with a little white meat from a rotisserie chicken. Do not give dogs the bones or skin from a rotisserie chicken, and if they are instructed to eat a low-fat diet, only feed the white meat portions. Other easy strategies to try to increase appetite include hand-feeding and microwaving the food to warm it up.
Acupuncture, while it cannot cure a condition, is known to reduce pain, inflammation, and nausea. Dogs with decreased appetites due to medical conditions such a diabetes, kidney or liver failure, inflammation of the pancreas, or hormonal conditions, such as Addison’s disease, are known to benefit and have an increase in appetite after acupuncture sessions.
When natural options stop working, it is time for pharmaceutical intervention. Mirtazapine is a common drug that is prescribed to dogs who have a decreased appetite due to other conditions that make them feel queasy, such as kidney disease or cancer, or medications such as chemotherapy. Mirtazapine acts on the central nervous system and increases serotonin levels, so it is important that it is not given to dogs who are on SSRIs (selective seratonin reuptake inhibitors).
Meclizine can help with appetite in some dogs. Meclizine is an antihistamine that is known to reduce nausea due to vertigo. If your dog is not eating due to nausea, there are several other medications available, such as maropitant, a common drug available through your local veterinarian.
Ghrelin Receptor Agonist
There is a new medication on the market for dogs that mimics the effect of ghrelin, which is the hormone that makes a dog or a person feel hungry. The medication binds to ghrelin receptors and signals the brain to cause the dog to feel hungry.
Finally, for those of you living in states where it is legal, CBD (cannabidiol) products manufactured for pets are exploding onto the veterinary scene. The benefits include reduction of pain and increase in appetite. It is important to note that CBD from hemp is not THC, and marijuana is toxic to pets. Ask your veterinarian for product recommendations.
It is important to note that these suggestions do not replace medical advice. If your dog is not eating and you have not seen your veterinarian, you should make an appointment to rule out serious underlying health issues that are causing your dog not to eat.
