Ask a Dog Vet and Get Answers to Your Dog Health Questions
Hi. My name is***** Thank you for your question about Patches. Grape / raisin toxicity is something that is real. I've seen a few dogs at my ER clinic that have had their kidneys shut down due to the toxin that is in them. Did Patches eat enough of the grapes to have a toxicity develop? That sometimes is where the unknown is. At this time, the toxic component of the grapes / raisins still hasn't been isolated. Can some be more potent than others depending on where they were grown or with what they were fertilized with? Could some dogs be more sensitive to the toxin than others due to underlying issues? There are factors that are being looked into.
Ideally in a situation like this, if I have a dog his size eat grapes of this amount, I will run blood work to see where their kidney values are at to begin with and then recommend being on IV fluids for 24 hours and rechecking the values to see where they are at. Really large ingestions are ones where I will diurese for 2 days.
That is good that he's not showing any symptoms at this time. It is way better that he's not lethargic, vomiting, or being "off". Maybe he's not one that is more sensitive to the toxin in the grapes or maybe these grapes weren't the worst of them. Maybe he ate less than the 8 grapes. The other maybe is that it is still too early to really see the signs if he's going to have kidney issues. One fairly consistent characteristic is that the dogs start to have GI upset and/or depression within the first 6-24 h of ingesting nephrotoxic levels of grapes.
I would take him to the vet to have them check his blood values of his kidneys to see what that shows. IF they are in any way elevated, then starting IV fluids would be the best thing to do. Grapes again are frustrating as some can eat that many at his weight and be in a world of bad. Others can do the same thing and not have an issue. At this time, his acting completely normal is way better than him having any clinical signs.
