I think salted porks are not the best choice, bacon, ham...high in salt and fat, not so much a great choice, I think chicken or beef is probably better you can control the level of salt and fat with those meats.
Gucci doesn't even really like ham, I never really tried to feed it to her, but I've never seen her beg for it..I've always thought it was bad like bacon and one of those risky pancreatitis foods (?)
Well, ham is salty, but good ham is NOT high in fat. In fact, most cuts of beef have more fat. I certainly wouldn't make it part of an every-day diet, but for small, occasional, training treats, many dogs love it and do fine with it. I don't buy ham for Kodi, but he has had bits of our left-overs here and there this week. We probably won't have another big ham until Christmas, so in the scheme of his entire diet, he's getting very little.
You definitely want to avoid any fatty meat because of the risk of a ham to your dog, because of the risk of pancreatitis. So obviously, you don't feed the fat on the edge of of the ham, but likewise, you wouldn't want to feed the fat from roast beef or steak, or the skin of chicken or turkey. It's not the animal it comes from, but the fat content.
In fact, pork loin is often cheap, very low in fat, and can be easily cooked up, diced and packaged for training treats. It also freezes well. I do that a lot. (and, of course, there's no added salt in pork loin, so that's out of the picture too)
