There is no known safe amount of grapes for dogs to eat. There is always a possibility of kidney failure. The (major) problem with treating these guys is that you don't know if it's going to cause kidney failure until it's too late. They don't act different or ill until they are life threateningly ill. The only way to treat them is to go to the clinic, make Rocky vomit if it was within an hour or maybe 2, then keep her on IV fluids for a day or two. And some dogs can eat grapes without any problems. We just don't know how each individual will react. So I know that's not the most helpful answer, but that's the more accurate one we have. You can chance it and do nothing and there is a good chance everything will be fine, or you can take him to the clinic immediately for hospitalization. Good luck!

    The toxic dose if grapes is unknown so one dog can have signs from a few while another can eat 50. it can damage their kidneys so it is something to monitor for. If you notice any vomiting or changes in drinking or urinating then he does need to get examined.

    Hi there! Thanks for using Petco Pet Education Center, formerly Petcoach! Grapes can be very toxic to dogs. It really depends on how many were eaten though some dogs, even large breed dogs, can have a toxicity with a small amount of grapes. Grapes can result in kidney failure and this toxicity is very serious. Usually, affected dogs are hospitalized for treatment and very carefully monitored. I recommend you consider having her evaluated by a veterinarian for further assessment and treatment. If your veterinarian cannot see you, you could consider an emergency clinic. Keeping my fingers crossed for a speedy recovery! Good luck and have a great day!

My dog is a black lab mix with hound and she ended up getting around 5 grapes in her system do to my child not knowing they can be harmful do you think this will hurt her
Hello. 5 grapes may or may not be a problem. We just do not have a threshold as to how many grapes may cause acute kidney failure. I would call your vet or nearest emergency clinic where they will get Miyah to vomit if the ingestion was within the past several hours. Actvated charcoal will be given & I V fluids started to really flush out her kidneys. This is generally continued for 36-72 hours while kidney function is monitored. If there is no kidney damage after 3 days, Miyah will likely remain unaffected. I hope all goes well & thanks for using Boop by Petco.

Is the a cure or treatment for a lung or kidney failure? after knowing that my dog had eaten a grape?
There is treatment available yes. The treatment usually involves bloodwork to check the liver/kidney values, fluid therapy to flush out the toxin ingestion, as well as detoxification of the GI tract with medications prescribed by your vet. I do hope that your pet does well and isn't too ill from the grape ingested. Each pet will react differently and the toxin amount ingested varies from pet to pet, so the kind of treatment can also vary some. Best of luck and take care.

This sounds quite serious, and I would take Frost into a vet immediately. The problem with grapes is that we don't know the amount needed to cause kidney failure, and even one or two could potentially cause it. It's concerning he won't eat or drink, and is vomiting everything, and that can be signs of kidney failure . He needs veterinary care now, please take him into a vet immediately. Best of luck.
