What happens if a Border Collie eats pork?

A Border Collie eating a little pork is fine; pork provides some protein, vitamins and trace elements, and moderate feeding adds nutrition. But pork is fatty and lower in protein than chicken, duck, beef and similar meats, so avoid overfeeding to prevent obesity.

Also, do not feed pork to Border Collies under 2 months, since their guts are immature and weak, and pork can cause indigestion with vomiting or diarrhea.
