Dogs may eat non-food items like plastic because they are curious about their taste or texture, or because they are hungry or bored. Some dogs may also chew and swallow non-food items due to emotional problems such as separation anxiety, stress, fear, etc. This behavior is called pica.
Unfortunately, ingesting non-food items such as plastic can lead to serious health problems, such as digestive issues, choking, Poisoning, etc. Therefore, if you find that your dog has swallowed non-food, it is recommended to seek medical treatment or consult a veterinarian immediately. At the same time, pay attention to providing dogs with enough food, water and toys to relieve their boredom and stress. You can also train dogs to obey basic commands and prevent them from eating things they should not eat.
