うちの犬、最近固いものを面倒くさがって食べないようになってきてしまった。まだ1歳なのに・・・【再】
My one-year-old beloved dog has recently started avoiding hard kibble, finding it too much bother to eat.
Apparently, the owner had consulted about this once before, but the issue wasn't resolved, causing continued distress.
Concerned why such a young dog is behaving this way, many online users are sharing similar experiences and advising vet visits.

Periodontal Disease (Dogs)
Canine periodontal disease is an inflammatory condition caused by bacteria proliferating between the teeth and gums, and it affects a surprisingly large number of dogs. It is so common that an estimated 80% of dogs over three years old suffer from some form of periodontal disease, but it can certainly occur in young dogs as well. Small breeds and brachycephalic (short-nosed) breeds are particularly susceptible due to their crowded teeth. The cause lies in food debris accumulating on teeth to form plaque, which then hardens into calculus (tartar), leading to widespread gum inflammation. Symptoms range from severe bad breath, red and swollen gums, bleeding, and loose teeth, to pain that causes dogs to avoid hard foods, chew only on one side, or lose appetite. As in the case of the dog in this article, a young dog of just one year old refusing hard food likely indicates oral pain or discomfort, which could be an early symptom of periodontal disease. Early detection and treatment are crucial; diagnosis is made through oral examination and X-rays by a veterinarian, and scaling or tooth extraction may be necessary. Daily tooth brushing habits and the use of dental care products are indispensable for preventing the disease and maintaining your dog's health.
Palatability (Dog Food)
"Palatability" in dog food refers to a dog's preference for and eagerness to eat a particular food. It encompasses not just whether a dog eats a food or not, but also qualitative aspects such as how enthusiastically they eat it and whether they finish it all. A dog's palatability is highly complex and influenced by various factors. The most significant factor is their sense of smell; dogs have a sense of smell thousands to tens of thousands of times stronger than humans, so the aroma of food greatly affects their appetite. They are often attracted to rich meat and fat scents. Taste also plays a role; dogs tend to prefer sweet flavors and dislike bitter ones, though their sense of taste is not as developed as a human's. Texture is also important, with preferences varying among dogs for crunchy kibble, wet food, or soft food. In cases like the current one, where a dog starts to dislike hard food, texture could be a major contributing factor. Other influences include food temperature (they often prefer food close to body temperature), types of ingredients, digestibility, past eating experiences, and even their living environment, stress levels, and relationship with their owner. If palatability declines, creative approaches to food type and serving (e.g., adding toppings, warming the food) can be effective, but it's essential to first consult a veterinarian to rule out any underlying medical conditions.
Abnormal Eating Behaviors in Dogs
Abnormal eating behaviors in dogs refer to various problematic actions related to eating that deviate from normal dietary patterns. Often dismissed as mere "fussy eating" or "pickiness," these behaviors are frequently caused by underlying physical illnesses, mental stress, or environmental changes, potentially signaling something from your beloved pet. Common abnormal eating behaviors include loss of appetite (reduced food intake, complete refusal to eat), pica (eating non-food items like stones, soil, or feces), polyphagia (eating excessively, stealing food from other dogs), fast eating, and selective eating (eating only specific foods). The situation described in this article—"finding hard food too much bother to eat"—can also be considered a change in eating behavior due to avoiding a specific texture. The causes are diverse; physical causes include oral problems (periodontal disease or pain), digestive diseases, kidney disease, liver disease, and other internal organ disorders, as well as endocrine abnormalities. Psychological causes include separation anxiety, environmental changes, stress, boredom, and demanding behaviors. When abnormal eating behaviors are observed, the most crucial step is to have a thorough physical examination by a veterinarian to rule out any medical conditions. Subsequently, a behavioral approach (reviewing the eating environment, selecting appropriate food, training, stress reduction measures, etc.) is needed to identify and address the root cause of the problem.
