I didn’t realize that a cookie, (actually two,) had fallen to the floor. I heard him crunch and looked up to see him pick up the third cookie. I snatched it away, but they were dark chocloate and I know that is not good for a dog. He is about 50 lbs. Should I do anything? Will he be OK? I once had a large dog eat a full pan of brownies and he was fine. My mom used to give her cockapoo bites of chocolate, and he lived. But dark chocolate is supposed to be worse, and of course, that is what I really like.
If you’re worried, you can induce vomiting. Hydrogen peroxide is a typical emetic, but I’m not a vet, so you can always call your vet to check.
Yes, dark chocolate has more Theobromine than milk chocolate , but I don’t know how much dark chocolate it takes to cause serious illness. It does take quite a bit of milk chocolate to cause serious illness in a dog. You might get some upset tummy from small amounts of chocolate. And, of course, how much dark chocolate was in the cookie? A thin layer coating the cookie would be less than say, squares of pure dark chocolate.
I have been told this calculator is quite accurate.

Dark chocolate dangerous levels are about 1.5 ounces per 10 lbs body weight.
ETA: good find Trubandloki!

I can’t take much credit.
A friend shared it with me when my dog ate some chocolates.
It saved me quite a bit of panic.

That’s a great tool. Most chocolate cookies have pretty low amounts of chocolate, so I wouldn’t worry.
(My dogs love chocolate cookies. And I’ll admit to giving them some…like an Oreo. I think the amount of chocolate is very low.)

My cat ate chocolate chip muffins. I tried inducing vomiting and it didn’t work. At any rate, he was absolutely fine, despite all that.
Try to figure out how many chocolate chips are actually in the cookie, but I think you probably are okay. Most chocolate isn’t real chocolate anyway. Check the label for ingredients.

thank you all. It was two chocolate covered shortbreads from Aldi’s. I love those. I was munching one, and the carton must have fallen to the floor. I realized he was eating something crunchy and I looked up as he carried the third one to right in front of me. I snatched it away from him, but he had eaten two. According to the site helpfully provided by trubandloki,it looks like he will be OK. But I will have to be more careful in future.

Don’t sweat it.
That’s a pretty small amount of actual chocolate for a dog his size.

My beagle has eaten a unopened container of Lindt chocolates and on a separate occasion ate my sisters pan of “special” brownies she was storing in her suitcase.
He is still here to sing the stories of his people.
I wouldn’t stress over two cookies.

Before we knew chocolate was bad for dogs…way back when…everyone in the family would share their (dark) chocolate cookies, cakes, ice cream etc. (though never pure chocolate squares because those were considered too good for dogs haha). All our dogs lived to be at least 15 years old…and were not all big dogs.
So no, I wouldn’t worry!

I think the true answer is “it depends” and consult your vet.
Anecdotally… my black lab ate a dozen costco double chocolate muffins (on the counter, not yet put away after getting groceries) when he was about a year old… other than looking guilty and feeling miserable for a day or so, he was fine.
I tried to induce vomiting but he seemed to enjoy the hydrogen peroxide and it did not cause him to toss his cookies as intended.

But Labradors don’t count. Lol! They have special tummy acids that enable them to eat things like a whole frozen ham or a pan full of soapy water. Not that these things ever happened to me. 
Seriously though I had a friend whose Daschund ate 2 dark chocolate Godiva squares and seized so badly he broke his back and died.

I hate to think how much chocolate our dog ate when I was a kid. She never had a problem. My mother’s Dalmatian had a thing for Devon fudge. She was almost killed, but it wasn’t an actual direct effect of fudge.

Be careful inducing vomiting, especially in cats. It can cause aspiration, which can lead to pneumonia.

years ago my sister was house sitting a lab. Some friends came for birthday dinner with really large and awesomely good chocolate cake. The next morning, Lab got the remaining cake (over 1/2) off the counter and downed it, plastic wrap and all. She did the peroxide thing to the Lab - he tossed up the cake and the plastic, and before she could stop him, he ate the mess all over again! She did get the plastic before it disappeared, and had to wait for the cake to return a 2nd time. COMPLETELY GROSS

Lab life! It’s a good thing they’re such great dogs because they can be quite disgusting.

How is Trooper doing?

Thank you for asking. He seems to be fine, aside from his problems with old age. A different vet told me last year that I thought he was about 12, she told me he was closer to 14, or 15. He has clouded eyes, and his teeth were terrible so I had to have a bunch of them pulled. Since I have no carpets, he has for the last year been scrambling over the floor. After two years of being fine, he can now barely walk on them. I finally coughed up some carpet runners, and they have helped immensely. But he is still an old dog. I thought about getting him a buddy after Toffee passed, but they weren’t close, and when I visit my sister with her small dog, and my niece with her two very rowdy dogs, he is not interested in interacting with them. Plus the staggering vet bills from various aliments last year convinced me I could just not afford another pet. as it is, I already have 3 cats, one of whom is very ungrateful, and I would give her away in a heartbeat but everyone I know is full up on cats.
Sorry, I got carried away…But Trooper is basically ok, and again,Thanks for asking!

I’m glad he’s doing ok. You might try this stuff. I used it for my old lab (we’ve always had tile floors and when he turned 14 he had real difficulty getting up and down).
