Batman and The Joker. Outdoor weddings and rain. Sunglasses and the sun. There are many great opposing forces in this universe, and in the world of dogs none is more infamous than that of dog vs. grape. Sure, dog vs. cat seems the more obvious choice, but I have seen a lot of videos of them getting along and not one of a dog eating grapes.

Let’s jump right in, shall we?

Can Dogs Eat Grapes?

Dogs can absolutely not eat grapes. Why exactly? The science verdict is still out as to why grapes (and therefore raisins) are so toxic to our horizontal pals. It doesn’t matter the breed, the size, male or female, young or old—all dogs can be affected. What is known, however, is that even just one grape can be fatal. Yeah, fatal.

Signs And Symptoms Of Grape Toxicity

If your dog has eaten some grapes, you may start to see some troubling signs and symptoms within the first several hours, including:

  • Vomiting
  • Diarrhea
  • Weakness
  • Lethargy
  • Uncommon stillness
  • Diminished appetite
  • Abdominal pain
  • Dehydration
  • Increased thirst
  • Increased urine production
  • Lack of urine
  • Kidney failure

While some of those signs and symptoms will be obvious to spot, others might be more difficult to notice, as our dogs don’t speak the same language we do.

Note: Typically, abdominal pain can be ascertained if your dog is sensitive to touch in the area.

It’s always frustrating when there are opposites on a list like that, and so when it comes to urine production or lack thereof, pay attention to the amount. With increased urine production, your dog may have an accident that is out of character. A decrease in urine may manifest as far as stopping urinating entirely.

As for knowing whether or not your dog is dehydrated—gently pull back the skin on your dog’s neck. When released, it should spring back quickly. If your dog is dehydrated, it will return slowly. Other signs include pale gums, a dry nose and mouth, and panting.

What To Do If You Think Your Dog Ate a Grape

Contact your veterinarian or an emergency vet clinic immediately. Treatment usually involves induced vomiting followed by ingestion of activated charcoal to try and absorb some of the toxin. Your dog’s caretakers may also administer IV fluids for the kidneys and medications to help ease nausea, maintain blood flow, and control blood pressure.

At the end of the day, Batman always wins. The rain stops. The sun sets. And in the battle of dog vs. grape, I have faith that the ancestors of wolves that prowled ancient earth can handle a few purple circles.
