My Dog Ate An Apple Core: What Now? (Solved & Explained!)

You’ve probably been told that apple cores have cyanide in them, which instantly brings up spy-cinema poisonings where the person who has been dosed drops dead in an instant. So, if your dog ate apple core, will this happen?

If your dog just ate an apple core and you’re worried sick, then you can relax. While apple seeds do contain trace amounts of cyanide, there’s not enough of it in a single apple core to poison your dog. Apple cores are more worrisome as a choking hazard, but likely your dog will just end up with a tummyache.

In today’s article we’re going to clear the haze a bit about the apple core so that you’ll have a better understanding about its actual toxicity when it comes to your dog. Read on to get the real scoop about apple cores and your dog!

So, Apple cores won’t really give your dog cyanide poisoning?

Okay, we’re going to start off by admitting that technically, your dog could get cyanide poisoning from eating apple cores, but it’s not very likely and we’ll tell you why very shortly. The reason that they have the reputation is scientifically sound. Apples have a compound which is called amygdalin and it converts to cyanide in their bodies.

Yikes – but wait – there’s a bit more to it than that. Vets have heard this little story quite a lot, as the internet really loves to make people worry, and so a number of dog owners have visited the vet in panicked droves because they’re dog got ahold of an apple core.

 So, what do the experts have to say to that?

Well, according to the ASPCA Poison control, your dog would need to eat 85 grams of apple seeds to be poisoned, which doesn’t sound like much but to put it simply – your dog would have to consume 200 apple cores to get that many seeds. So, if your dog ate ONE, they’re not going to get cyanide poisoning – period.

So, apple cores are safe to give as a treat?

Eh, it would be alright if it wasn’t for the choking hazard. Apple cores are a bit more fibrous, making them harder to chew and to break up, and dogs don’t really help with their whole ‘gobble it whole before my owner changes their mind’ mentality towards most treats.

This makes apple cores quite the choking hazard and so we simply cannot recommend them as a regular treat option or apple-core disposal method (since we get rid of a lot of our leftovers via the ‘Dog-o-matic’ option).

If your dog manages to get a hold of one or two and to completely swallow it, there’s also no guarantee that they won’t have a little gastrointestinal distress. Dogs stomachs differ from pooch to pooch, and while some will digest these with no problems, other dogs might have diarrhea and a serious belly ache.

It’s better to stick to treats that aren’t going to harm them or if your dog has developed a taste for Red Delicious or Granny Smith apples, then you can simply cut them up first and leave the core out of the equation. Your dog gets their apples, you don’t have to worry, and everybody wins!

Do dogs like apples?

Some dogs absolutely LOVE apples, immediately ‘parking’ themselves in view the moment that you start peeling or chopping one up for yourself and giving you ‘that look’ until you decide that it might be nice to share.

This is perfectly fine to do, but you’ll want to set a few ground rules to ensure that your furry friend doesn’t get a tummyache. Apple have a good nutritional profile, with calcium, fiber, phosphorous, and a goodly amount of Vitamin C in the bargain. Even so, while your dog can certainly have some, it’s still tricky to digest.

As such, the best way to sate your dog’s cravings is going to be a compromise. If it’s your dog’s first apple, then give them a single slice, but if they are already veteran apple fans then you can give them 2 or even 3 slices – just be sure to keep it at that.

Keep the skin or remove it, just make sure that the Apple is washed and neatly sliced, and as a bonus the fibrous fruit acts like a natural toothbrush and it will freshen your dog’s breath a little. If your dog loves the apples, 1 – 3 slices every day should be the maximum amount that you give them.

What i my dog ate a rotten apple, core and all?

Rotten apples are quite aromatic and when you consider that your dog’s sense of smell is estimated to be anywhere from 10,000 to 100,000 times better than our own, your apple loving dog is eventually going to find and eat a rotten apple.

Our advice for this would be simply be ‘don’t panic’. While rotten apples are certainly nasty, if your dog manages to eat the whole thing without it becoming a choking hazard, then a case of diarrhea and an upset stomach are going to be the most likely outcome.

You can help to soothe your apple lovin’ buddy with some canned pumpkin (not the pie filling, which is too sugary and will come right back up), and this will help to settle their stomach and hydrate them a bit until the diarrhea can run its course.

Make sure that your dog has plenty of water, as well, as they need to stay hydrated. If your dog stops drinking the water, displays a lot of discomfort, has blood in their stool, or the diarrhea doesn’t go away within 2 days then you’ll need to get the vet involved, but otherwise they should recover quickly.

Some final words on cyanide cores

Today we’ve addressed the popular ‘apples are chock full of cyanide’ story and the truth is, while they do indeed have amygdalin and this CAN convert to cyanide, your dog would have to eat 200 apple cores in order to actually poison themselves with the famous cinema-cyanide method.

That said, we don’t recommend apple cores as treats, but your dog can have 2 – 3 slices a day if they want to and it will even freshen their breath up a bit. Just start being careful about how you dispose of the cores after your dog gets a taste for them, otherwise you’ll have to start guarding the trash bin!
