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

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.

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.

Hi, I dont’ think the vomiting and diarrhoea is related to the grape ingestion. It could be that she has also eaten something else ! I would recommend to have her checked over 48 hours post ingestion to check her blood, to make sure that everything is fine. Hope this helps !

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

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.

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!
