Anything that can cause a dog to feel ill, such as kidney disease, pancreatitis, intestinal parasites, liver disease, cancer, infection, intestinal obstruction, etc., can lead a dog to refuse food and water. Like humans, dogs cannot go for more than a few days without water, so this should be treated seriously.
If your dog isn't eating, consult a vet within 8-12 hours if there is any accompanying vomiting or diarrhea. Absent these symptoms, there's a few likely reasons your dog isn't eating, including emotional issues.

How long can a healthy dog go without eating? Most healthy dogs can go up to five days without food, though that number is only true if your pet is still drinking plenty of water. Some can even go up to seven days without, though you should never let things get that far without taking your dog to the vet.

If your dog is avoiding food but is drinking excessive amounts of water—much more than is normal for him—this is a telltale sign that he has develop diabetes.

Force-feeding your dog should not be your go-to solution if it refuses to eat food. Sometimes dogs may want to skip a meal or two if they are not hungry, which is entirely normal. Give your pet a little time, and just put its food within reach. If it eventually feels hungry, it will eat on its own.

Persistent vomiting and diarrhea can cause rapid dehydration, and damage to the intestines and immune system can cause septic shock.

Change in appetite
If you notice a sudden change in your dog's appetite, he may have come into contact with roundworms. Dogs that are infected often lose their appetite or, in some cases, have a sudden increase in hunger.
If a dog begins showing signs of stomach upset but is still willing to eat and drink, its owner can first try offering a bland, low-fat, highly digestible diet to resolve the issue. “Boiled, skinless chicken or turkey breast mixed with white rice or low-fat cottage cheese can be offered in the short term,” Gould said.
Herbs are another natural stimulant that can work well when added to dog food. Choices such as chamomile, ginger, celery seed, and peppermint are among the herbs that tend to work best. Garlic seems to have the highest success rate as dogs enjoy the taste and it naturally boosts the immune system.
Other more serious reasons for a dog being sick include infection, worms, eating foreign bodies such as socks or toys, or swallowing or licking certain flowers, plants or toxins that are poisonous to dogs. More critical medical issues such as cancer or kidney, liver, or pancreatic disease could also be to blame.
Coughing, diarrhea, vomiting and lethargy are the general signs the dog has worms. Other symptoms depend on the type of worm. For example, if your dog has a tapeworm, clear identifiers can be rapid weight loss or what appears to be grains of rice in their stool.

How does it spread? Parvovirus is highly contagious and can stay on surfaces and in environments for a long period of time—withstanding heat, cold and humidity. Dogs can contract the virus by interacting with infected dogs, or by coming into contact with contaminated faeces, surfaces or environments.
