I do not recommend using pig rinds for dog food. A dog's gastrointestinal system is different from a human's, so dogs cannot eat the same foods as humans. Their gastrointestinal systems are better suited to digesting animal meat, bones, and vegetables. Using pig rinds as dog food may cause your dog to suffer from gastrointestinal problems and may lead to malnutrition or other health problems.
Dogs should eat dog food specially formulated for them, which is usually made of animal protein, vegetables, fruits and grains consist of. If you want to provide your dog with meat as a source of nutrition, it is recommended to choose dog-friendly meats such as chicken, beef, or lamb. When feeding meat to dogs, you should also avoid feeding meat with bones in it, as dogs tend to chew bones, which may lead to injury or accidents.
