Dogs might think they’re human, but their physiology is not like ours. Humans might eat a wide variety of foods with little concern, but there are some very common human foods which you should not feed to your canine companion. You’ve probably seen the foods on this list before, but this is WHY these foods should not be fed to dogs.
Everybody’s heard that chocolate is bad for dogs, and it’s true. Chocolate contains a compound called Theobromine. Theobromine is a type of compound called a methylxanthine, and another methylxanthine you might be more familiar with is caffeine. We know quite a lot about these compounds, as humans use them both medicinally and recreationally. The long version is that they all inhibit phosphodiesterase and antagonise adenosine receptors. The short version is that they increase muscle activity, including the heart, and stimulate the central nervous system.
This presents as dogs that have fast and irregular heart rates, high body temperatures and increased muscle activity that can progress to seizures.
It takes a reasonable amount of chocolate to poison a dog. One M&M isn’t going to do it. For a 35kg dog it’s going to take at least 3500mg of theobromine, which is about 5kg of typical milk chocolate. But only 1.2kg of dark chocolate or 600g of cooking chocolate, which is possible.
A 10kg dog needs much less. 1.5kg of milk chocolate would do it, which is only about 3 large Easter Bunnies, or 300g of dark chocolate, which is one packet from the cooking isle.
Chocolate is super tasty, dogs will absolutely gorge themselves on all chocolate available, so it’s not too difficult to poison smaller dogs with it.
And even if you get the dog through the toxicity, the high fat content of chocolate can go on to cause other gastrointestinal problems.
Yes, I said onions AND garlic. All allium species contain the same potentially toxic compounds, whether raw or cooked. That goes for spring onions too, it’s just really difficult to convince a dog to eat enough of them to be poisoned. These plants cause a Heinz body anaemia by inducing oxidative damage to the surface of the red blood cells, and for some reason breeds of Japanese origin like the Akita and Shiba Inu seem particularly prone to this toxicity.
It usually takes 10 to 15g per kg of body weight to poison a dog, but those breeds can be affected by as little as 5g per kilo. So for a big, 35kg dog, that’s about three medium sized onions.
Poisoning can happen all in one go, or it can happen by eating small amounts over a longer period of time, which is why it’s infuriating to see garlic being suggested as a natural remedy for things.
Bad cases will have to be treated with a blood transfusion as there is no direct antidote. And for interest, there are other things that can cause Heinz body anaemia too, like zinc.

This bad little boy is super rare to find!!! This is a mitotically active cell present in peripheral blood circulation from a dog - only the second one I have ever seen!!
As a game, in the diagnostic lab we yell KABLAM! anytime we see a mitotic figure. The first one to say kablam wins :-P We should so turn it into a drinking game…
There was a sensitive pragmatic question which needed to be answered, however. To put it bluntly: Was Arya going to be naked on camera? Many cast members have appeared nude on the show, though typically signed on when they were at least 18 years old (and often agreed to nudity as part of their deal). The 22-year-old Williams joined Thrones when she was 11 and has grown up in front of fans. Williams says the showrunners let her decide precisely how much to show. “David and Dan were like: ‘You can show as much or as little as you want,’” Williams says. “So I kept myself pretty private. I don’t think it’s important for Arya to flash. This beat isn’t really about that. And everybody else has already done it on the show, so…”
Still, when it came time to film the encounter, Williams had to be naked-ish on set, and that was a naturally a bit awkward. “In the beginning, everyone was really respectful,” she says. “No one wants to make you feel uncomfortable which kind of makes you feel more uncomfortable, because no one wants to look at anything that they shouldn’t look at which in turn makes you feel like you look awful because everyone is kind of like—” [Williams averts her eyes]. “You want people to act more normal.”
Continues Williams: “Then [the scene] was rushed. We were [directed by] David Nutter, who has a habit of speaking fast anyway. By the end we’re rushing to finish the scene and David is going, ‘Okay, you’re going to come in and do this and do that and, great, take your top off’ — and then walked off. And I’m like … ‘Okay. Let’s do it.”
Dempsie suggested the experience was strange for him too for given how long he’s known Williams, who’s about a decade younger than him. “It’s obviously slightly strange for me because I’ve known Maisie since she was 11, 12 years old,” says the 31-year-old actor. “At the same time, I don’t want to be patronizing toward Maisie — she’s a 20-year-old woman. So we just had a lot of fun with it.”
But Williams says what’s most important to her about Arya’s battle-eve night of romance wasn’t reading the scene or even filming it, but rather what this moment meant for her character. Year after year, Arya has been laser-focused on survival and training and revenge. Being with Gendry meant that, for one night at least, Arya had an experience that put her back in touch with her humanity.
“It was really interesting because it’s a very human relationship for Arya,” Williams says. “This is something she’s stayed away from, an emotion we’ve never really seen her engage with. David and Dan were like, ‘It’s the end of the world, what else would you have her do?’ This may be is a moment where Arya accepts death tomorrow, which she never does — ‘Not Today.’ So it was that moment where she says, ‘We’re probably going to die tomorrow, I want to know what this feels like before that happens.’ It’s interesting to see Arya be a bit more human, speak more normally about things people are scared of.” — Maisie Williams discusses Arya’s surprise Gendry scene
About to burst
A geyser forms due to water being heated by the energy beneath the Earth’s surface. The water is heated past the normal boiling point of water, but remains in a liquid state because of the pressure of the water on top of it.
Eventually, enough water turns to steam that it begins blasting the column of water upwards. Once the first bit of water is removed, the pressure drops, causing more water to turn to steam and leading to a runaway eruption of the water.
