Long story short I work for my parents mechanical contracting company and I brought my dog to work today and my dad gave him a raisin thinking it was ok. Nope! They are toxic to dogs. I called the vet and they said to watch him to look for signs of toxic poisoning and call the poison control center if he starts throwing up or anything like that. Now I can't concentrate on work I'm so worried about my poor pup! Have any of your dogs eaten a grape or raisin and were fine?
