does raw pork bones give dogs ringworm ?

Ringworm is a fungal infection of the skin, so no.

The guy who gives me bones also said that pork bones were no good for my dog too.But mine like them and are well so i still give them,do others give pork bones too?

Perhaps they mean tapeworm?

British pork no longer contains tapeworm either.......

I feed raw pork to mine regularly.Never had any problems and all 5 dogs love it.Pigs trotters is one of their favourites!!!!
