My dog ate grapes days ago, no symptoms. Is kidney damage a risk?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 15 lbs

My dog loves frozen grapes and i just read that it is very dangerous for him to eat them. He isn't showing any symptoms of sickness and the last grape he ate would have been at least 3 days ago. Do I need to worry? Obviously, he won't be eating them again.

Some dogs can eat grapes without getting ill or having kidney failure, others cannot. Next time you visit a veterinarian with Riker have some blood work done to make sure he has healthy kidneys. Should Riker get lethargic, start drinking a lot of water or has diarrhea or vomits. All these could be signs of kidney disease.

It may or may not be related as no one knows the toxic dose of grapes and it can vary between dogs. If there is no change in appetite or an increase in drinking and he is acting normal then you can continue to watch him. If you notice any of those symptoms irnhe continues to vomit then I would get him checked

Thank you for submitting your question regarding Joker. Diarrhea is not a common symptom of kidney disease. It is likely not related to the grape ingestion. Typically a dog with kidney dysfunction will vomit, drink excessive water, refuse food and be lethargic. However, it is best to see his veterinarian for bloodwork so you know for sure and don't have to worry. I hope this information helps!

Grapes toxicity in dogs causes acute kidney failure, the most common symptom of kidney failure is excessive drinking and urination. i strongly recommend taking her to the vet urgently for a urine analysis and blood test in order to assess the potential damage to the kidneys.

My puppy ate a grape yesterday and is lethargic. Is it kidney failure?

I would be more worried about him having a viral infection such as parvo, especially if he has not had the full course of vaccinations. It would likely take several days before you would see signs of kidney failure caused by the grape ingestion. I do suggest you take him to a veterinarian ASAP as both parvo and kidney disease are life threatening conditions.

My dog ate grapes. Could she still be poisoned without symptoms?

There are no home remedies to prevent any adverse effects from rapes, but poisoning events and kidney failure are quite rare. Not all grapes/raisins appear to be toxic so I recommend monitoring for any change in thirst and urination

My chihuahua ate raisins, no symptoms after 24 hours. Is she okay?

Thanks for using Petco Pet Education Center, formerly Petcoach. Unfortunately, the answer is “there is no way to know”. Not all dogs will develope any type of kidney injury. The dogs that do get kidney damage sometimes do not show signs on bloodwork for up to 72 hours. To be safe I’d say do a kidney blood panel and urinalysis on Monday. Realistically though, if there is no increased drinking or urinating or any other changes by tomorrow, she is likely to be just fine. Best of luck to you and Luna!

My dog ate grapes 5 days ago. Is she okay if no other symptoms?

Symptoms of grape toxicity usually begin within 24-48 hours of ingestion, so Arlee is likely to be ok if she's had no other symptoms 5 days after eating them. The exact dose of grapes to cause toxicity is unknown, so it is very important that you don't allow Arlee to eat anymore grapes (or raisins). If she's got a rash, then I would take her into your regular vet to be evaluated for that, as there are a few different things that can cause a rash, and she may need medication to help clear it up.

My dog ate grapes. Blood test high, vet says okay. Should I worry?

How naughty of Hector to get into some grapes! It is extremely encouraging that his kidney values (particularly the creatinine and BUN) are within a normal range. The SDMA value is thought to be of use in detecting early signs of chronic kidney disease, but is not of much value when concerns about acute kidney disease arise (as in the case of grape ingestion). Remember that there is a wide range of normal to account for individual variation and values at the higher end of this normal range do not typically indicate a problem. I can see that Hector's ALT (a liver value) is mildly elevated, but in all honesty, I do not worry about elevations in this value until they are about twice the upper limits of normal (>240, whereas Hector's value is 181). That said, it is still worth asking your vet if it is possible simply to recheck this value in another week or two. It will most likely return to normal, but if it remains high or increases further, ongoing monitoring of the ALT and further diagnostic testing (bile acid testing, abdominal ultrasound, etc.) may be indicated. I hope this helps to clear up any confusion and that Hector continues to do well after eating grapes!

My dog ate grapes. How long to watch for grape toxicity symptoms?

Grape toxicity can cause kidney disease and failure. An increase in drinking and urination along with anorexia and vomiting are common side effects of that. These generally stay within 24 hours with the most severe starting 24-48 hours. So 2 days is the time to monitor for any toxicity

My dog ate raisins 12 hours ago, no symptoms. What should I do?

Unfortunately, it's hard to say how raisins or grapes will affect a dog as tolerance can be different. I would continue to monitor Sasha just in case, and if you notice any issues such as vomiting, diarrhea, changes in appetite, lethargy, excessive (or no) urination, abdominal pain, confusion, etc, take her in for care ASAP.
