Dogs can suffer from anorexia, a condition that can occur in both normal and abnormal pets. Symptoms are evident when the owner places food in front of the dog and the animal does not pay attention, not even sniffing at the food. In some cases the dog will just walk away.
Anorexia can be divided into two kinds. The first, which affects male animals more often than females, is when the pet is not physically ill. For instance, some dogs develop anorexia or related eating problems when they have a new owner, move to a new house, or experience some other stressful event that affects their emotional health. In other cases, anorexia is the result of owners spoiling their pets. When a dog refuses to eat a certain kind of food, the owner may look for another brand that the pet will eat. Now the pet understands how to get its master's attention, and so it becomes increasingly selective over what it eats. Over time, this can lead to anorexia.
The second and more common kind of anorexia is when the pet is really sick. There can be many causes. Dehydration, for example, can lead to low blood pressure, depression, and weakness. Ultimately, the pet may lose its ability to eat. Other ailments that can contribute to anorexia are diseases of the liver and kidneys, diabetes, and problems with blood circulation.
We can prevent anorexia in several ways, but it starts with observing the pets' behavior at meal time. First, if you notice that your pet is not eating properly, try to observe its reaction and compare it with a normal scenario. Also, try to observe whether it vomits or has a bad stomach. When a new pet is brought into the house, you should not change the food immediately. Try to give it the same type of food it is accustomed to eating. This will reduce the animal's stress. Pet owners should also train their pets to eat at fixed times. If they do not eat at meal time, take the bowl of food away after 10 -15 minutes. Pets can do without a meal for one whole day.
It is important for the pet owner to notice other types of behavior, such as their pet's bowel movements, whether it is vomiting, how much interest it shows in playing around, and its appetite for snacks as well. It is definitely not normal when the pet won't eat its favorite snack. In this case consult a local veterinarian immediately. The vet should be able to make a diagnosis based on past behavior, a blood test urine analysis and/or X-rays. Certain adjustments can be made to change the pet's behavior if it seems to be suffering from anorexia and is not really ill.
