Why does your dog eat anything andeverything including sandpaper?

Dogs do not typically eat sandpaper or other indigestible items. If a dog is consuming inappropriate things like sandpaper, it would be imperative to consult with a veterinarian to rule out health concerns, such as medical conditions or nutrient deficiencies, that may be motivating this behaviour. In some cases, excessive licking or swallowing of non-food items can indicate gastrointestinal or neurological issues and should be brought to the attention of a health professional promptly.
