Snickers is chocolate with peanuts, caramel and nougat, which makes it heavy on every front.
What is on the label
I pulled the ingredient list for Snickers from Open Food Facts (product code 0040000524311). Ingredients are listed from the most to the least by weight.
Milk chocolate (sugar, cocoa butter, chocolate, skim milk, lactose, milkfat, soy lecithin), peanuts, corn syrup, sugar, skim milk, lactose, salt, egg whites, artificial flavor.
Recipes change, and flavors and package sizes can differ, so read the bag you actually have before you rely on this list.
What matters for your dog
- Chocolate. ASPCA says chocolate is toxic to dogs because of compounds called methylxanthines. It says the darker the chocolate, the greater the risk, that white chocolate has the least, and that baking chocolate and cocoa powder have the most. Milk chocolate is the first ingredient on this label.
About Snickers
The label lists milk chocolate first (sugar, cocoa butter, chocolate, skim milk, lactose, milkfat, soy lecithin), then peanuts, corn syrup, sugar, skim milk, lactose, salt, egg whites and artificial flavor. No xylitol, raisins or macadamia nuts are listed.
The chocolate is the problem. Pet Poison Helpline says chocolate contains theobromine and caffeine, and that the severity depends on the amount and type of chocolate and your dog’s size and health. A full-size bar is a lot of chocolate for a small dog.
Snickers also comes in minis, fun size, Almond, Peanut Butter and ice cream versions. They have different labels and different amounts. I checked the standard bar.
If your dog already ate some
Write down what it was, how much, when, and your dog’s weight, and keep the package. Then call your vet, ASPCA Poison Control at (888) 426-4435, or Pet Poison Helpline at (855) 764-7661.
Don’t wait for symptoms if the snack has chocolate, xylitol, or a lot of onion or garlic in it. And don’t try to make your dog vomit with salt or salt water. Pet Poison Helpline says that can cause salt poisoning.
Questions people ask
Can dogs eat Snickers?
Chocolate is the first ingredient, and ASPCA says chocolate is toxic to dogs. Call your vet or Pet Poison Helpline if your dog ate any, with the amount and your dog’s weight.
Is the peanut part a problem?
The peanuts are not what ASPCA’s list flags here. The chocolate is. The label also lists no xylitol.
My dog ate a fun-size bar. Is that serious?
It depends on your dog’s weight and the type of chocolate. A small dog needs far less than a big one to run into trouble, so call and ask rather than guessing.
