Your senior dog no longer eating is already a cause for concern. But what does it mean if your dog also had diarrhea? Let’s take a look at the most likely causes that can lead to both a loss of appetite and diarrhea, and review 4 steps to take at home now to help your dog.
What Are the Most Likely Causes?
The following conditions cause loss of appetite, as well as vomiting and diarrhea, with diarrhea often the most commonly observed symptom:
1. Dietary Change
If you have suddenly changed your dog’s food, it can cause your dog to have diarrhea. Many times, your dog will still be eating and not be vomiting. This diarrhea will go away after a few days on its own. When you switch your dog’s diet from one brand to another, it is best to do so gradually over 5 to 10 days. This will help prevent your dog from having diarrhea. Many times, your dog will not need to see a vet and will quickly recover from this diet change.
Parasites can cause your dog to stop eating and have diarrhea. This can easily be diagnosed and treated by your vet. There are even over-the-counter dewormers that you can give to your dog for some of the most common types of parasites. In a severe parasite infestation, your dog may also stop eating. Usually, dogs with parasites will still be very active and playing – just having diarrhea.
3. Heat Stroke
If your dog becomes overheated, they can develop heatstroke. Some dogs will love to stay outside for long periods of time. Without access to cool fresh water, shade, and sometimes a fan they can develop heatstroke. Dogs who have heat stroke will be panting and drooling. They may also vomit sometimes and have diarrhea.
Below are other conditions that typically will cause both vomiting and diarrhea, in addition to loss of appetite:
Pancreatitis is inflammation of your dog’s pancreas. This is a common condition that will cause your dog to vomit and have diarrhea. Pancreatitis is caused by your dog eating a high fatty meal. Your dog will also have a very painful stomach and not eat. Pancreatitis can be treated but in severe cases can be fatal. Sometimes your dog will need to see your vet for IV fluids and injectable medication for them to recover. For mild cases of pancreatitis, you can try at-home treatment of a bland diet but if your dog does not stop vomiting and eating after 24 hours, they will need to see your vet. The cost of this workup and treatment at your vet can be $500 to $1500+ depending on the severity of your dog’s condition.

This condition can cost $500 to $1,500+ depending on how severe your dog’s condition is and where you live.
7. Toxin Ingestion

4 Steps You Can Take at Home to Help A Dog Who is Not Eating & Has Diarrhea
There are a few things that you can do at home to help your dog who is vomiting, having diarrhea, and not eating. Note that you should not give your dog new medication (even over-the-counter medication) without first discussing it with your veterinarian:
- Withhold food for 4 to 6 hours: If your dog’s stomach is upset, not giving them food for a few hours will allow their stomach to calm down. When you start to offer food again make sure it is a small amount of a bland diet.
- Entice them to eat: Some dogs will eat more willingly if they are offered human food. Things like chicken and rice. Also adding a scrambled egg to their food will help. When cooking any human food for your dog, try to make it as bland as possible. No fats, oils, butter or seasoning should be used as this can make your dogs stomach issue worse.
- Give them a Probiotic: If your dog is vomiting and having diarrhea they have also disrupted the normal bacteria flora found in their stomach and intestines. Common probiotics that you can find at the pet store are Fortiflora and Profivex.
- Give them over-the-counter gastrointestinal medications: Some gastrointestinal medications used for people can also be given to dogs. Things like Pepcid and Imodium can help dogs with GI issues. Pepcid can help decrease the gastric acid build-up and help your dog who is vomiting. Immodium can help decrease your dog’s diarrhea. Before starting any new medications ask your vet to make sure your dog can take these medications.
