Dogs usually are hearty eaters. Most of the time, they enjoy chowing down their food. They even find stale food or garbage delicious!
But even a chow hound may occasionally lose his appetite due to stress, a lack of exercise, or even a change in the weather.
Temporary appetite loss in dogs is not serious - dogs are by nature hardy animals and can stay healthy and active even if they don't eat for 48 hours.
Believe it or not, dogs are very in tune with their bodies. When they do not feel so well, or when they feel there is a need for internal cleansing (like detoxification), they fast on their own.
But if your dog suddenly has no appetite and energy for more than two days, coupled with weight loss, then you should take her to the vet for a check-up. The appetite loss is most likely caused by some underlying health problem.
As you can imagine, there are many possible reasons why a dog may lose her appetite. Some common ones include:
Dogs are animals of habits - they like routines and dislike stress! So when a dog's daily routines are disturbed, or when there is stress in her living environment, she may lose her appetite.
Some examples of stressors could be when there is a new dog in the family, or when she is put in the kennel while her owners are on vacation.
Digestive problems such as diarrhea, vomiting, constipation, inflammatory bowel disease, and so on, can also cause a dog to lose her appetite.
If your dog stops eating because of diarrhea and/or vomiting, don't force food down her throat. Fasting for a day or so in this case is actually good for your dog. Just remember to encourage her to drink water to prevent dehydration.
Of course, you also need to find out and address what causes your dog to have diarrhea, vomiting, or other digestive issues.
Infectious diseases usually cause fever, which in turn may cause a loss of appetite in dogs. In this case, it is also natural and beneficial for the dog to fast.
Temporarily going without food allows the body to devote less energy to digestion and more to fight the bugs that make him sick.
Again, be sure to keep the dog hydrated. One good way is to give your dog some unsalted chicken soup or this Only Natural Pet Human Grade Bone Broth for Dogs & Cats. The taste may entice the dog to drink the soup, and the nutrients in the soup can help the dog fight the infection as well.
Sometimes, a dog has no appetite when he is suffering from an upper respiratory disease (e.g. asthma, kennel cough). Perhaps the dog doesn't want to eat because he cannot smell the food!
Other health problems that may cause dog appetite loss include:
As you can see, a loss of appetite in dogs can be caused by quite a few different diseases. Be sure to get a medical check-up if your dog stops eating for over 48 hours.
For the occasional loss of appetite in dogs (and if the dog is otherwise healthy), try some of the following to appetite stimulants.
Many dogs like the taste of garlic and in fact a small amount of garlic is good for dogs as it can boost a dog's immune system. (If you are unsure if garlic is safe for dogs, please be sure to read this page.)
Next time when your dog is not eating, trying mixing a small amount of finely chopped fresh garlic (one-eighth to one-fourth of a teaspoon depending on the size of the dog) to his food. The garlic taste may just be the thing that can entice him to eat.
Other herbs that are not only appetite-stimulating but also nutritious include peppermint, fennel, alfalfa, and dill. Just sprinkle some of these dried herbs on your dog's food.
Depending on the cause of your dog's loss of appetite, you may want to try using various essential oils to help!
For example, if your dog doesn't eat due to stress, consider diffusing some calming and relaxing oils to help ease her stress and calm her down. Lavender (Lavandula angustifolia) and Roman Chamomile (Chamaemelum nobile) are two gentle, dog-friendly calming oils that may help.
If your dog has a digestive issue, you may want to use essential oils that can give digestive support to help your dog. Peppermint (Mentha x piperita) and Ginger (Zingiber officinale) are two good choices.
If your dog just has a sluggish appetite, diffusing some oils that are appetite-stimulating may help perk up her appetite. Citrus oils, such as Sweet Orange (Citrus sinensis) and Grapefruit (Citrus paradisi), as well as the oil Sweet Marjoram (Origanum majorana) are good for stimulating a sluggish appetite.

This homeopathic remedy is effective for dogs who have lost their appetites due to indigestion or constipation. Dogs that need this remedy may vomit or retch. They are depressed and irritable especially in the mornings.
Carbo vegetabilis
This is another remedy that is effective for dogs who have lost their appetites due to poor digestion. Dogs needing this remedy often have gas, and are usually lethargic and weak.
You may also want to consider some of these suggestions to help your dog get his appetite back:
Some dogs may stop eating when they do not like their food! If your dog is reluctant to eat her food, try feeding her a new type of food to see if the change can do the trick. If she eats the new food heartily, then you have found a solution to the problem (provided of course that the new food is natural, and of high-quality.)
Dogs (and cats for that matter) love to eat foods that have strong smells. By warming the dog food a bit, it becomes more aromatic and may just be the way to get the dog eating again.
Sometimes a dog's appetite loss is caused by his owner! Maybe the dog is being given a few too many treats! If you think that's the case for your dog, try to give him fewer treats (sorry Fido!). Remember, as a general rule, treats should constitute no more than 10% of a dog's diet.
If your dog's appetite loss is due to poor digestion or indigestion, give him supplements of digestive enzymes to help him digest food and absorb nutrients.
If the appetite loss is due to digestion problems (such as diarrhea, gas, vomiting, and so on), this Chinese herbal supplement may help:
