Can Dogs Eat Swedish Fish Candy? It’s Dangerous

If you like fish-shaped candy, you almost certainly have a bag of Swedish Fish stowed away in your pantry. You’ve undoubtedly pondered what would happen if your dog got his paws on a bag of Swedish Fish candy if you’re a dog owner who enjoys candy.

Is it true that dogs can eat Swedish fish? No, dogs are not allowed to consume Swedish Fish or any other candy. While there are no specific components in Swedish Fish candy that are hazardous to dogs, it does include sugar. Large amounts of sugar consumed at once can result in stomach distress, cavities, weight gain, and diabetes.

We’ll explain why dogs shouldn’t eat Swedish Fish in this post, as well as what to do if your dog does. Continue reading to learn more!

Is Swedish Fish Good for Dogs?

To cut a long tale short, Swedish Fish candy isn’t good for your dog or you! In terms of nutrition, these fish-shaped sweets are high in empty calories and lack critical elements.

Sugar, inverted sugar, and corn syrup are the first three components of Swedish Fish candy. Given that dogs require proteins to flourish, it’s evident that sweets won’t suffice to meet your dog’s nutritional requirements.

Furthermore, these sweets lack the vitamins and minerals that your dog’s body requires to function effectively throughout the day. It’s also worth noting that Swedish Fish candy is devoid of nutritional fiber, which means it won’t help your dog’s digestive system.

Overall, eating Swedish Fish candy will not bring any nutritional or health benefits to your dog. In reality, the empty calories in this candy will only lead to your dog gaining weight and becoming fat.

Side Effect of Swedish Fish for Dogs

The good news is that Swedish Fish candy is free of xylitol, a naturally occurring sweetener that is extremely hazardous to dogs (source). So, if your dog gets to sneak a few candy when you’re not looking, don’t get too worked up!

However, consuming these fish-shaped chocolates is not without risk, and there are certain adverse effects. The following are some disadvantages of giving your dog Swedish Fish candy:

Too Much Sugar

Swedish Fish candy, as previously said, comprises sugar, invert sugar, and corn syrup, among other things. The amount of glucose and fructose in each of these sweetening products varies.

There isn’t much else in the way of nutrients that can slow down the pace at which your dog’s body absorbs glucose and fructose. As a result, your dog’s blood sugar levels will skyrocket after eating this fish-shaped candy, followed by a crash.

Furthermore, sugar molecules can attract water from your dog’s cells, causing water to accumulate in the body. Excess water in the body might make it difficult for your dog to stay hydrated, resulting in electrolyte and salt imbalances.

Digestive Problems

Ingesting an excessive amount of Swedish Fish candy in one sitting might create intestinal issues in dogs. The sugar in this candy might induce vomiting and diarrhea in dogs if taken in big amounts.

Keep in mind that some dogs may get constipation as a result of ingesting too much sugar. If your dog has a digestive problem after eating Swedish Fish, know that it’s because of the sugar in the candy.

Teeth Cavities

Believe it or not, dogs can acquire cavities and rotting teeth from consuming too much sugar, just like us (source). Sugar is used by bacteria in your dog’s mouth to make acid, which eats away at the enamel, causing tooth decay.

Furthermore, germs from your dog’s teeth might travel to his gums, causing gingivitis and other unpleasant dental issues. You may wind up spending a lot of money on treatments and dental operations depending on the severity of your dog’s dental troubles.


Swedish Fish, like many other candy, is high in empty calories that will do nothing except make your dog gain weight.

While eating a few candy here and there won’t harm your dog right now, it will lead to weight gain and obesity in the long term. Obese dogs are significantly more prone to get diabetes, heart disease, and joint pain as a result of their excess fat.

Obesity is a serious problem for many dogs and their owners, and it isn’t something that can be corrected fast. As a result, keep track of how much food you offer your dog and avoid human foods and snacks that are high in sugar and calories (source).

How Much Swedish Fish Can a Dog Eat?

After eating a few Swedish Fish sweets, some dogs will get diarrhea and vomiting, while others will devour the entire bag without having any negative effects.

The amount of fish-shaped candy your dog may consume is determined on their size, age, breed, and overall health. Nonetheless, you should never give Swedish Fish to your dog and keep candy packages out of reach of your dog.

A tiny dog, such as a Chihuahua, may have a severe sugar surge from eating a handful of Swedish Fish candy, while a Great Dane may not be affected. However, just because your dog is large does not indicate that it is healthy or safe for him to consume candy.

What to Do If Your Dog Eats Swedish Fish?

It is contingent on how much Swedish Fish your dog consumed. It’s probably not a big deal if they just have one. Naturally, various dogs react differently to sweets, and it relies on a variety of factors, including their age, past health issues, and size.

It’s one thing for a Great Dane to eat Swedish Fish, but it’s quite another for a Pomeranian to eat the same thing.

If the amount of candy is so little and you’re positive, you should keep a tight eye on your dog’s behavior for 12 to 24 hours.

If your dog ate the entire bag of Swedish Fish, you should take him to the veterinarian immediately away. Your veterinarian is the one with whom you should make contact in such a case.

Food and Candies Dogs Can Eat

While you should keep your dog away from sweets and other sugary foods like Sour Patch Kids, there are certain human foods that are appropriate for dogs to eat. Just keep in mind that most human meals should be consumed in moderation by dogs.

Cooked eggs, meats, seafood, simple popcorn, apple slices, and peanut butter are some of the things your dog may love (as long as it does not contain xylitol).

If you’re still unsure if dogs may eat Swedish Fish, keep in mind that while certain varieties are not poisonous, it’s better to avoid large levels of sugar.


Despite the fact that some dogs are born with a sweet appetite, no dog should consume sweets or candies. While some dogs enjoy the taste of Swedish Fish, it includes sugar, which may be hazardous in big quantities.

Instead of sweets, you may give your dog a variety of healthy fruits, vegetables, and human meals as rewards. When it comes to dogs and Swedish Fish, it’s best to err on the side of caution and stick to dog meals that are safe.
