Do you have a sick dog who won’t touch his food? It can make you worry and wonder … just how long can a dog go without eating? Here’s the short answer: Healthy adult dogs can typically go as long as 3 to 5 days without eating any food, as long as they have access to drinking water. However, this is just an average figure for an adult dog.

How Long Can A Small Dog Go Without Eating? Smaller dogs may not be able to go as long as larger dogs without eating. To err on the side of caution, it’s best to make sure a small dog doesn’t go more than 3 days without eating.


How Long Can a Sick Dog Go Without Eating? If a dog is sick, especially with a digestive upset of any kind, it’s perfectly normal for him to not eat for a couple of meals, or even a couple of days. Dogs will naturally fast themselves if they don’t feel well, so don’t insist on trying to get him to eat. Giving the digestive system a break with a 12-24 hour fast is a great way to resolve diarrhea. Still, since not eating can be a sign of more serious conditions, if your sick dog hasn’t eaten in 2-3 days it’s a good idea to talk to your holistic vet.

Why is My Dog Not Eating His Food? Let’s take a closer look at why your dog isn’t eating, and a few things you can do about it. There are a few reasons for loss of appetite in dogs, and different causes will have different solutions. Since loss of appetite is a common indicator of illness in dogs, you should pay close attention to your dog’s eating habits. If your dog usually eats well but suddenly refuses to eat, it’s often a sign of one of the issues below.


Pain Or Illness Loss of appetite is one of the most common signs of illness, especially if it’s accompanied by vomiting, diarrhea, or other symptoms. Just because your dog isn’t eating doesn’t mean he has a serious disease … reduced appetite can also be a sign of dental pain and discomfort from a broken or loose tooth, or gingivitis. However, if your dog has lost his appetite, it’s still wise to get your vet’s help to find out the cause. Not eating could be a symptom of serious conditions like cancer, liver disease, kidney disease, pain, or systemic infections.


Vaccinations Or Medications All vaccines also carry a risk of adverse effects …one of which is a loss of appetite in dogs. Usually, this is minor and brief … but if the appetite loss continues, you should contact your veterinarian.


When it comes to your dog’s health, it’s crucial to work with a holistic veterinarian who can recognize the side effects of vaccination, especially since veterinary homeopaths are skilled at treating vaccine reactions.


Loss of appetite in dogs is a common symptom of frequently prescribed medications, such as antibiotics. Typically, these signs will begin to show within a day or two, so it’s important to pay close attention to your dog if he’s taking any prescription medication.


Sometimes, a dog’s lack of appetite isn’t due to an illness or medical reaction but could be attributed to pickiness. Dogs may not eat at certain times or in situations where they feel uncomfortable or stressed. Reasons for dog anxiety can range from a new home to travel or house guests, and they may need time to adjust. Most dogs will eventually eat and won’t starve themselves for long.


However, if your dog’s lack of appetite persists, it’s important to investigate other possibilities to ensure it’s not a sign of illness.


Occasionally, dogs won’t eat but will continue to act normal. They won’t show other symptoms and will continue to drink water and even eat treats, maintaining their usual energy for activities and play. In this case, it’s possible your dog is suffering from temporary digestive issues or has simply decided he no longer likes his food. Consider this possibility if you’ve recently changed his food or if the formula or ingredients of a commercial food have changed.


If your dog isn’t eating but is acting normal, it’s likely to be less serious, but if it doesn’t improve in a few days, it may be time for a food change or a consultation with your holistic vet.


If your dog hasn’t been eating for multiple days, you may need your vet’s help to rule out any illness that requires treatment. The next steps will depend on whether your dog has a medical issue.


If your dog isn’t eating because he’s become picky, or is uncomfortable with his mealtime or is in a new environment, there are several approaches you can try:


– Change up your dog’s food. If you feed homemade raw or cooked, try a different recipe. If you feed premade raw, try a different protein or brand. Or if you feed processed food like kibble, consider adding or switching to canned dog food.


– Walk your dog before mealtime to stimulate his appetite.


– Change bowls, or where you feed your dog. Your dog may feel more comfortable eating in his crate or in a quiet corner of the home.


– Don’t show your dog you’re stressed by him not eating. Be cheerful and matter-of-fact when you feed him, and if he’s not interested, just pick up the food and offer it to him later.


– Cut back on the number of meals. Many people feed twice a day, and a lot of picky dogs eat better with only one meal a day.


If your dog is experiencing a loss of appetite, there are several nutritional strategies you can try to stimulate their interest in food. First, experiment with feeding at different times of the day to find a schedule that works best for your pet.


Temporarily reduce or eliminate treats to avoid overfeeding and to encourage your dog to eat their regular meals.


Regularly provide prebiotics and probiotics to maintain gut health, which can be crucial for a dog’s overall appetite and digestion.


Consider giving bone broth or raw goat milk as a source of nutrients that can help improve your dog’s appetite.


Explore natural options to stimulate appetite, such as CBD oil, which some research suggests may help stimulate hunger hormones. CBD oil can also alleviate pain or anxiety, which might be the underlying reasons for your dog’s lack of appetite.


If your veterinarian concludes that your dog’s lack of appetite is due to an illness, treatment for the underlying condition will be necessary. Some vets may recommend a prescription diet, but it’s important to note that most prescription diets are not of high quality and are not recommended for long-term use. Instead, consider a fresh whole food diet, preferably raw, to see if it improves your dog’s appetite.


Avoid forcing your dog to eat, even if they haven’t eaten for a few days. In extreme cases, your vet might recommend a liquid diet, subcutaneous fluids, or even inserting a feeding tube.


If your dog hasn’t eaten for a week, it’s crucial to seek immediate veterinary attention. Healthy dogs can typically only go up to 5 days without eating before they start experiencing health issues.
