I'm sure I'm not the first to think of this (& actually my wife was the first in our house - I'm apparently pretty slow on the uptake), but I haven't seen it mentioned on UPH (maybe I've just missed it). Since I'm now convinced mean seeds have killed BOTH my springers, my next one WILL wear a vest to at least help minimize the chances of grass awns introducing themselves through the skin. Please consider this as a preventative measure for YOUR dog. And be aware that these things can enter your dog any number of ways. Paws, eyes, ears, larynx, skin, whatever. Read through the entire sticky thread "Dangerous seeds" at the top of this forum.
