Is your dog different from his usual lively and enthusiastic dog? Do you notice some of its strange behaviors, such as suddenly not eating or drinking? Many people are plagued by various rumors and misunderstandings, and may think that dogs are "waiting for death" if they don't eat or drink. Is this really the case? Let's walk into the world of science together to understand the truth of the facts. 
First of all, we must understand that dogs are our human friends and partners in our lives. They will have a variety of behaviors and expressions, some sweet, some playful, some cute, and some angry. However, sometimes certain behaviors of dogs may cause us to be troubled, for example, the dog suddenly stops eating or drinking. Since dogs can't speak, and we can't directly interpret their inner world, so for the dog's sudden non-eating or drinking, we must first keep a normal mind, don't panic excessively, and guess whether it is "waiting for death".
As a professional pet breeder, what I want to tell you is that if the dog does not eat or drink, it is likely that the dog has some kind of health problem that needs our timely attention and care. A dog's appetite and mental condition reveal to us their physical, emotional and health conditions, so when the dog is not eating or drinking, the first thing you need to do is to understand and solve the problem.
There are many possible reasons why a dog does not eat or drink, such as it may be digesting a certain food, or it may have gastrointestinal problems. At the same time, dogs may refuse to eat due to pain, nausea, collapse, or other conditions that cannot be ignored. If the dog does not eat or drink, but can still play and run, then the dog may only have some minor pain, you can try to give it some food that the dog likes to see if it has an appetite. However, if the dog neither eats nor drinks and appears irritable or even exhausted, then you should take it to the veterinarian immediately. Only a veterinarian can give an effective diagnosis based on the dog's specific symptoms and physical condition.
What to do if your dog suddenly stops eating? First of all, as mentioned earlier, don't panic. You can take your dog to a quiet place and try to provide him with different foods to see if he has an appetite. If the dog still doesn't eat it, then you'd better take it to the veterinarian immediately.
When your dog doesn't eat, you may start to worry about whether there is a problem with the type and quality. It is true that some low-quality products may cause a decrease in your dog's appetite, or cause other health problems. Also, dogs may like different foods for different reasons, so you can try changing your food offering strategy to see if it improves. Overall, when your dog no longer has an appetite or is unwilling to drink water, he is facing some problems. And these questions are probably not "waiting for death", but the dog can't tell you what it's going through in human language. So, don't let any misleading opinions get you into worry, and don't try to guess or solve the problem yourself. Remember, your dog is an important part of your life and deserves the same care and medical care as a human. Therefore, at any time, the health of the dog should cause us to pay close attention.
For dog lovers, dogs may have a loss of appetite or be unable to eat for various reasons, which is a problem that we must face and deal with. Only by having an in-depth understanding of the dog's needs and respecting the dog's habits can we truly provide the care that the dog needs. Loving the dog well is the best feedback we can give to the dog.
