Pig ears are generally safe for dogs. They can be controversial, mostly because of a salmonella outbreak in 2020. This was a serious incident that involved the hospitalization of humans. However, these types of events are very rare, and they can happen in all sorts of products, not just pig eras. Generally, pig ears are safe, especially if you go for pig ears with no added chemicals or preservatives. They're boneless, so you don't have to worry about that, but they can be crumbly, and small pieces may break off, which always creates a small risk, but most dogs manage this just fine. You know your dog (and their eating habits) best, so it comes down to a personal choice.
