Why do dogs suddenly lose their appetite?
A dog's appetite is an important indicator for owners to observe whether the dog is healthy in daily life. There are many reasons why dogs are picky eaters and anorexia. Basically, they are as follows:
Behavioral problems: When the dog reaches the age of 4-5 months, the dog will become interested in more food flavors. If you let your dog taste many different flavors during this stage, it will Eat selectively. This is the main reason why dogs are picky eaters.
Food issues: Preservatives commonly used in food can produce smells that dogs don’t like, as well as the smell of certain foods themselves, causing dogs to not eat the food you give them just because they don’t like the smell.
Stress reaction: Sudden changes in dogs such as long-distance transportation, changing residences, changing owners, temporary foster care, etc. may cause a loss of appetite due to stress reactions, including changes in seasonal climate, which can also cause changes in the dog's appetite.
Malnutrition: Lack of minerals and vitamins may also affect the dog's diet due to the destruction of the dog's own nutritional balance. Long-term picky eating and anorexia worsen malnutrition.
Gastric ulcer: Dogs suffering from gastric ulcer usually eat very slowly, which is also an important reason for dogs' poor appetite. As long as the gastric ulcer is treated, appetite can be completely restored. Eating shelf-stable food containing preservatives and irregular diet are the main causes of gastric ulcers in dogs. Long-term picky eaters and anorexia can also cause gastric ulcers.
Thyroid problems: Hypothyroidism, the inability to secrete enough thyroid hormone, slows down the dog’s metabolism. The dog's appetite decreases and he eats very little food every day, but he will not lose weight and may become fatter and fatter; at the same time, he will be lethargic, lazy, obese, and have dry hair every day. Hypothyroidism can be treated and these symptoms disappear after treatment.
Oral problems: Dental disease, gum swelling, oral ulcers or wounds, etc. can also directly affect your dog’s food intake.
When a dog's appetite changes and decreases, if it is suspected to be caused by gastric ulcer, thyroid, oral disease or other serious diseases, we need to diagnose and treat the dog in time. Usually, as the disease is cured, the appetite will gradually return to its original state. .
