Welcome to Just Answer. My name is Jane. I have been involved professionally with dogs in the healthcare and behavioral fields for over 20 years. I’ve worked as a Vet Assistant and Behaviorist and have extensive experience in dog reproduction, as a breeder, for even longer than that.. It will be my pleasure to work with you today.
Yes, raisin and grapes are bad for dogs. And dogs that have consumed large quantities of grapes have developed kidney failure. Here is a link to a site, which talks about this.
The ASPCA study showed that as little as .15-.32 ounces per pound could have a toxic response. You can read more on this here:
Treatment is frequently I.V. fluids at 1 ½ times the maintenance amount and monitoring the kidney values for a few days. You will need to estimate the weight of the raisins ingested to get an idea of whether there is the possibility of a toxic response. I don't think a couple of raisens is going to do anything to them but you should monitor them for symptoms of vomiting, possible loss of appetite and diarrhea, just in case for a few days. If you see any signs of toxicity, have them seen immediately. Many owners will go ahead and take them in anyway to have their kidney values monitored.
I hope I've given you great service. If so, I'd appreciate a 5 star rating. The rating should be based on my answer and not any site issue.
