Onions, garlic, alcohol, chocolate, coffee, macadamia nuts, raw bread/pizza dough, foods containing the sweetener xylitol (birch wood), salt, moldy food, currants, grapes and raisins can cause poisoning in dogs. Grapes and raisins are especially dangerous, potentially causing kidney failure, or even death.
Until recently, I did not realize how serious this is. We used to have a very large dog, a Leonberger named Bronco, who weighed 140lbs when he was not overweight. He seemed to have a stomach made of steel. On one occasion, Bronco got hold of a box of chocolates in the shape of small gnomes. Each gnome was filled with liquor—some with gin, some with vodka, some with whiskey, and some with rum. It was a gift from Rachel, our daughter, who had just come back from a visit to China. She had bought the present for us at the airport in Hong Kong.
What happened was that Bronco ate the entire thing—tinfoil wrappers, chocolate, liquor, and all. We were afraid he might get very sick, and we carefully monitored him, ready to rush him to the emergency clinic if necessary. Fortunately, nothing happened, except he threw up a little bit of tinfoil. I guess he had a stomach of steel. Below is a picture from Bronco’s gingerbread house raid. We laughed. It was just funny.

What this experience did not teach me is how dangerous certain foods can be to dogs. Bronco was fine eating the chocolate gnomes, and gingerbread houses, and you can laugh when it all ends well. However, recently Claudia and I witnessed the death of a dog who had eaten raisins. This was a shocking experience. It reminded us that knowing what food is dangerous to dogs is very important and preventing them from eating food that is dangerous to dogs is crucial. If you are not willing to keep track of this, don’t get a dog.
The Death of a Dog
Warning: The Story Below Can be Triggering to Sensitive People, Skip if Needed
A few weeks ago, I mentioned that we took our mini-Australian Shepherd Rollo to the emergency. We took Rollo to the veterinary emergency because he had thrown up three times within six hours. He had been chewing on a lot of rawhide which is a bit risky, so we were worried. He got an X-ray and various blood tests. However, everything was normal. It was probably just a stomach flu or upset stomach. He received anti-nausea medication, and another medicine.

We like this emergency clinic because you can remain with your dog the whole time and participate in everything they are doing. The drawback is that you are in a big room with a lot of other dogs and their owners, and you’ll see everything that is going on, which sometimes is not pleasant, and this time we witnessed a shocking tragedy. We had to wait a long time because almost all of the attention was given to a dog who had eaten raisins. We were there from about 1:00AM to 5:00AM. We were clearly not a priority, but we did not complain.
About the same time as we came in a man and a woman brought in a sick dog. They also had a very tired little boy with them. He was maybe three years old. The dog was throwing up, and he was lethargic and obviously very sick. We overheard that he had eaten raisins. Suddenly the dog had a seizure. The nurses/doctors took blood samples. Then he had another even more severe seizure, and then another. It looked bad. The tests showed that his kidneys were shutting down. After a while the veterinarian informed the couple, and the boy, that the dog was dying a painful death and that the best might be to euthanize him.
They took the dog and the rest of the family to a private room. After a while the woman ran out of the room. She was crying hysterically as she ran out of the emergency clinic. She couldn’t control herself. The man and the boy came after, also crying, but they were calmer. The man paid the bill at the front desk, and they left. Claudia and I and Rollo, we just sat there, and we watched it all. We saw them bring out the dead dog from the room. It was a show that we had not anticipated and that would stay on our minds, maybe forever. We were told Rollo’s tests were fine and that his stomach was fine, and we paid, and we left. It was quiet in our car on the way home.
When I came home, I walked over to the pantry and I grabbed the raisins box and was about to throw it in the garbage, when I decided to just hide the box far into the pantry and never buy raisins again. I don’t like throwing away food.


That is so very sad. Our dogs hate raisins and if they accidently happen to be in something they are eating, they spit them out. It’s as if they know they are not good for them. Believe me, they eat everything else!

That’s really sad to hear . I’m glad Rollo was okay , but that’s really sad for the other family .
I’m always paranoid about certain foods being in my home and ingredients or plants . We don’t have poinsetta’s in the house ever , I throw away any products with Xylotol , even if it’s cosmetics . Choclate is stored in the fridge and we just eat , any other strange things get walked to the garbage outside . Roxas my doberman, ate my brown sugar blackened fish fillet . I called the ER vet and they told me as long as it was real sugar , he would be fine . So I took it to heart. Still good to think about what items we bring into our homes .

Thank you so much Oliveunicorn. Yes I’ve read that Xylotol is really bad for them. Their digestive system is different and it is important we know what is toxic to them. It is great that you keep track including avoiding dangerous house plants. We try to do the same but we failed on many occasions (Bronco’s chocolate, liquor, unhealthy pies, etc.) This experience was a reminder of how bad it can get.
