We have jumbo cow ears for dogs available in bulk or in a 12 pack bag from free range (grass fed) cattle from Brazil. These are a low fat, non greasy alternative to pig ears. As many consumers are more aware of what chews they provide for their dogs, the jumbo cow ears are becoming a popular chew for many. These are supplied in boxes of 50 units. These are a non-bleached natural ear and therefore has no white colour.
