I think I read somewhere once that grass seeds can be dangerous to dogs but can't remember exactly what else the article said. Can anyone fill me in?
Yes they can be dangerous, and can even cause life threatening absesses! If you take your dog out in the grass, groom him after to remove any plant matter and so on caught in his fur.
Yes, be very careful as these seeds bury into the skin(it can happen in humans too) and have to be removed by a vet.
