The idea of feeding raw pork to their dogs will horrify many pet parents. Humans and dogs alike should never eat undercooked pork as the meat may contain various parasites.
Heartworms and roundworms can both be carried by pigs but what you need to worry about is trichinella spiralis which causes trichinosis a potentially serious gastrointestinal disease.
Dogs may vomit and have diarrhea due to upset stomachs.
You may notice some stiffness when your dog moves when he has a weaker immune system a sign that he is suffering from pain.
A simple way to avoid such an infection is to freeze pork meat and bones for at least three weeks beforehand.
Several large pork shoulder bones can be stored in your freezer for a few weeks if you have a large freezer.
Having performed this your dogs bone should no longer contain parasites. Especially on a hot day your dog will appreciate receiving a bone straight from the freezer.
