anyone know where i could find a decent list of which foods are toxic for dogs online??? i know some, like chocolate, onions, etc. and i know sugary, greasy, salty foods aren't good (just like they are not good for us) but i am looking for a good list. i didn't know that some dogs couldn't have grapes until i read it here today (and to think i tried to give my b/f's chihuahua a grape last night, but she wasn't interested, EEP! could have been bad) i think that supplementing a dog's diet with a variety of healthy "treats" is a good idea but i want to make sure i don't accidentally give something bad. thanks oodles for any help!
