I’ve heard people say that a dog can eat anything, after all, they eat from the trash. Perhaps they do, when they have no other choice. Just like a homeless person will eat from the trash when they have no other choice, but it doesn’t make it right, and it certainly isn’t healthy.
Keep in mind that not everything you put into your body is good for you, and it is no different for a dog. Many packaged foods contain salt and preservatives that can cause complications for humans, which means that it can possibly be worse for a canine.
