Generally speaking, dogs will not die if they are hungry for a day or two, because they can maintain their energy needs by consuming their own fat, but this does not mean that hunger is harmless to dogs. Dogs are often hungry and full, which is easy to cause emaciation and gastrointestinal diseases.
What's the harm of a dog being hungry for three days?
In addition, a few months old puppy can't be hungry. Dogs within 3 or 4 months are prone to hypoglycemia if they don't eat for a day, which will be life-threatening, especially puppies with small size and weak stomach. If it is an adult healthy dog, as long as there is enough clean water and you don't eat for a day, there should be no big problem. Although dogs won't starve to death if they don't eat for a day, they can't be without water. They must prepare enough water for the dog, and the water source must be clean to ensure that the dog will have no problem drinking it. Each variety is different. Whether a dog can endure hunger for a few days depends on the dog's physique. If the host is going on a business trip and has no time to take care of it, he can put the rice on a big plate for several days at a time. Or send it directly to a nearby pet hospital or pet agency.
