In their effort to thwart my gardening someone uprooted an entire onion. Then someone ate half that onion. Now someone (Tar) has onion breath. To the googles! Yes, onions are bad for dogs. Really, really bad. If in distress (despite looking guilty, guilty, guilty) take to the vet. Good news is that the damage is reversible and we're really taking long term onion eating causing anemia. So Tar is on the watch list. Right now he is racing around the backyard chasing Abby.
