When your pet won't eat or drink it can be an indication of a serious problem. Any change in your pet's usual dietary habits is generally worth a trip to the veterinarian and in some cases it is an emergency. When your pet refuses to eat or drink and is lethargic, vomiting, has diarrhea or exhibits other symptoms like shaking, fever or drooling he or she could be very sick. Time is an important factor in treating your pet and the sooner the better when it comes to the veterinary exam.
Most dogs will not refuse to eat. This is called anorexia and it is a serious concern. The underlying cause of the anorexia should be diagnosed by a veterinarian and the sooner the better. Dogs and cats sometimes eat objects that cannot be digested (foreign body) and these can make our pets feel so sick that they cannot eat. Other conditions like disease, cancer, obstruction or severe pain can also be at the root of the problem. There may be other reasons that your pet refuses to eat or drink.
If your pet generally eats well and his or her refusal to eat is out of the ordinary it is advisable to treat the matter as an emergency. Even finicky cats react to temptations of their favorite treats. When your finicky eater refuses to eat or drink it can be difficult to tell if she is in distress. Changes in your pet's eating and drinking habits should be communicated to your veterinarian or to the emergency room doctor without delay.
