I heard a rumor that chocolate was toxic for dogs too. Never heard of the grape thing.

Chocolate is toxic to dogs and cats, not a rumor.

Semi sweet chocolate chips made my Sheltie very sick. He was a real chocoholic and got the odd M&M or two, but he got in a grocery bag and found the dark chips. The dark chocolate is MUCH worse than milk.
I had a long haired chihuahua/Pom mix who ate M&M's every day of his life. Lived to be almost 19. Go figure.
No chocolate is probably best, but that dark kind is the worst.
Never knew about grapes and raisins. Good to know for future reference. Thanks!

Also, sighthounds are extremely sensitive to hops and can be poisoned by them.

The miserable things grow wild here and it's a constant battle to eradciate them.

Dogs can't digest the cocoa in chocolate, so it causes severe gastrointestinal problems. Onions are also toxic for dogs.

Chocolate is harmful to dogs. It contains a chemical that their livers can't process. I give my dog carob drops from PetSmart.

I used to give him grapes. He could have eaten a whole bunch in one sitting if I had let him - he loved them so much. Then I read in Reader's Digest that grapes are harmful to dogs - damages either their liver or kidneys; so that treat was immediately stopped. Nowadays I won't even buy grapes for myself because I don't want him to beg for them.
