My dog ate a grape. Is it toxic? What should I do right away?

There is chemical in grapes that is toxic to dogs but 2 grapes will contain a relatively small amount. Usually issues arrise when dogs eat a whole packet off raisins. I would monitor Bruno closely and visit the vet if he seems to be unwell.

Hello. This is always a bit of a quandary because there are no hard rules for raisin & grape consumption in small amounts. A few raisins in a 60-pound dog is probably or no consequence, but some dogs can react to just one. Personally, I would just watch Buddy. Most problems will develop in 6-24 hours, & consist of vomiting &/or diarrhea. If any of these should develop, get to your vet immediately. No vomiting or diarrhea by 48 hours, then he will be fine. Just be diligent in keeping an eye on him. Thank you for using Petco Pet Education Center, formerly Petcoach.

I don't think a big guy like Toby will suffer and bad effects from eating one grape. The skin on the grape contains the toxins, but it would take many more than the one grape to cause him a problem. The same situation for raisins....not a good snack. I feel sure that Toby will be fine!!

Oh no, poor Rosie! Grapes are highly toxic to dogs and can cause acute kidney failure, leading to signs of lethargy, vomiting and inappetence. Rosie needs to go to an ER vet immediately, as this could be a life-threatening emergency. The vet will be able to examine her, determine her kidney values on lab testing (CBC, chemistry, urinalysis), and start her on IV fluid therapy with other supportive medications. Good luck!
