My Dog Hasn't Eaten In Almost 3 Days, She Won't Eat Anything, What Could It Be?

The best piece of advice is to take your dog to the vet immediately, as there is no way of saying exactly why your dog will not eat without knowing the full circumstances. A dog can go 24 hours comfortably without eating, but once the dog has stopped eating for a number of days then that it is a signal that the dog is very sick. It's very unhealthy for the dog to starve like this, too, so it's important that you book in with the vets so that they can take a look at your sick dog.

In the meantime, there are some things you can do to try and make your dog eat. You can open your dog's mouth to check for injuries to the gums, cheek or teeth, too. It could be that your dog is in pain and will not eat for this reason. In which case, try giving your dog some soft food like tinned dog food. You may even want to put some milk in a bowl as the milk will provide nutrients but will not rub up against the gums. If you are going to give your dog milk then it is generally healthier to provide it with goat milk. The dog will be able to stomach it much more easily than cow milk.

You could also mix one cup of milk with an egg, and add some sugar for flavor. This is what you should offer your pet whenever it doesn't eat. The egg is rich in nutrients and the milk has calcium, and like mentioned before it will not rub against the gums. It's really easy for the dog to digest too, and also acts as a way of soothing irritated stomach linings of dogs.

My dog is moping around is being sick not persistent but in spouts he is drinking and is hydrated but will not eat he tried a bit off human food s I would rather him eat than not eat at all I'm starting to get really worried he ate a little bit off sausage roll

My dog is having the same problem. About 2 weeks ago, he got his first vaccinations and has slowly declined since. I am out of town, and took him to the vet when his eating declined to nothing. He was vomiting for two days so I took him to a vet here. I believe he has caught something from the OTHER vet because the "new" vet said there is no pain associated with something lodged in his intestine. He is having to be force-fed yogurt (which he hasn't thrown up, and is another sign nothing is lodged there). He will drink his own water when he is thirsty enough, but I give him some in his mouth when it's been too long since he drank last. I also last night wanted him to eat some protein, so I spooned some "burger mush" into his mouth along with his yogurt. Could it be the stress of a long trip and now not being at home? I'm calling the vet again today, she may need to run blood tests.

My dog is very sick.  We took him to a vet because he has lost weight and is not eating.  They said the blood work came back normal, but he has a urinary tract infection.  They gave us antibiotics 2 days ago, but he seems worse now that he did when we took him to the vet.  Has anyone else seen anything like this?

First of all- Take your dog to the vet!
 
it is obvious your pet is very sick. That is not normal for a dog not to eat and to be vomiting. You could lose your dog to dehydration.

The lost of appetite can be because of heat but if the dog is losing weight then it is bad. He might be seriously sick. It may also be an adjustment of the dog's eating habits. Dogs eat much in the growing age. But whatever the condition may be, you must take the dog to the vet.

Take him to see a veterinarian so they could get him a remedy for it. He may be sick because illnesses can spoil appetites. Hurry up and do this before the condition worsens.

Dehydration will kill your dog. Take it to the vet asap. It sounds like parvo.

Yes, it sounds like parvo, a virus that eats the stomach lining so your dog can't tolerate anything, including water.  if it is parvo, your dog will need to be hospitalized to prevent dehydration.  good luck.
