Hi Melissa, Many a dog has had gut surgery to remove parts of corn cobs. Not a good treat for a dog with powerful jaws! The fibrous cob is totally indigestible and if ingested can cause serious blockage in the intestine. There is a lot of cellulose in the kernals and the dog cannot properly digest those, if you want to feed veggies for a chew treat give him a piece of broccoli or carrot stick. Generally for a dog to obtain full food value it is best to grind up the veggies.
Even if your dogs are nibblers and you are supervising them and removing the cobs as soon as they are finished others should be mindful that most Berners will crunch and swallow chunks. Be careful Rose T.
