Is Swedish Fish Good for Dogs?

The short answer is that Swedish Fish candy is bad for your dog and bad for you as well! This fish-shaped candy is full of empty calories and contains no essential nutrients. 

Sweden Fish candy contains sugar inverted sugar and corn syrup as its first three ingredients. The fact that dogs need proteins to thrive makes it clear that eating candy would not satisfy their nutritional needs. 

Furthermore these candies do not contain any essential vitamins and minerals that your dog needs in order to function properly. Additionally Swedish Fish candy contains no dietary fiber so it will not benefit your dogs digestive system.

As a whole your dog would not benefit from eating Swedish Fish candy nutritionally or health-wise. This candy is full of empty calories that can make your dog gain weight and become obese. 

The short answer is that you should not give Swedish Fish to your dog.

This is shocking to me.

Despite the candy not containing any specific ingredients toxic to dogs it does contain sugar which is not good for them.

Ingesting small amounts of sugar can be okay for dogs but eating large amounts all at once or over time can be dangerous.

How Sugar Affects Dogs

Wikipedia lists sugar invert sugar and corn syrup as ingredients in Swedish Fish. All of that adds up to a lot of sweetness.

Dogs can accumulate water when they eat sugar because the sugar molecules draw water from their cells.

Dogs may not be able to drink enough due to this buildup which can lead to electrolyte imbalances especially with sodium. It is possible to become toxic from too much sugar.

The microorganism balance in the gut can also be upset by sugar leading to problems like vomiting and diarrhea. Despite the fact that these are not fatal a little candy is not worth your dogs misery. Not to mention the cleanup you’ll have to do.

Furthermore sugar can cause teeth cavities and weight gain both of which are huge (no pun intended) problems for dogs.

Acids are produced in the mouth by bacteria using sugar in candies. As a result decay is caused by these acids eating away at the enamel and coating of the teeth.

It is inevitable that your dog will eventually develop problems such as metabolic changes obesity and diabetes as a result of prolonged weight gain.

One or two Swedish Fish are not a big deal if you give them to your dog. There should be no problem with your dog. In the event that your dog ingested a whole bag of Swedish Fish you should call your veterinarian as this amount of sugar is toxic for dogs.

It’s best to err on the side of caution when asking yourself “Can dogs eat Swedish Fish?”. You can give your dog a few sweet treats here and there but you should stick to safe dog treats.

Types of Candies Dogs Shouldn’t Eat

Dogs are generally not supposed to eat candies but two kinds are particularly toxic:

  • Chocolate
  • Candy containing xylitol

Here’s a closer look at each:


Dogs can become ill and even die when they eat powdered chocolate in even small amounts.

Dogs have difficulty metabolizing Theobromine a molecule found in chocolate.

It is a good idea to never give your dog chocolate and to keep it locked away in an upper cabinet so that your dog cannot access it.

While chocolate does not always cause death it can cause seizures and other health problems. A small dog seems to be more affected than a large dog by dark chocolate and dark chocolate is more toxic than milk chocolate.

Any amount of chocolate ingested by your dog should be treated by a vet.

The symptoms your dog may exhibit include nausea (excessive drooling) vomiting diarrhea drinking lots of water and a rapid heartbeat.

Candy with Xylitol

Sweeteners such as xylitol can be found in sugar-free foods such as gum mints and candies.

In addition to peanut butter sugar-free desserts medicines toothpaste and mouthwash it is also found in some types of toothpaste.

Xylitol increases a dogs insulin production when it is ingested. It is possible to develop hypoglycemia as a result of this increase which is very dangerous.

Any product with xylitol should not be given to your dog. You should always store these items and other harmful foods out of reach of your dog.

When you eat candy its tempting to share it with your dog especially if hes sitting at your feet begging. Nevertheless you should be aware that he may suffer some harm from it. Obesity cavities and diabetes can all be caused by too much sugar just as they are in humans.

Other Foods Dogs Shouldn’t Eat

Dogs can also be poisoned by many other human foods. Here are some common types of foods dogs should avoid:

The effects of coffee or anything containing caffeine is similar to those of chocolate.

It is possible to develop stomach problems and more serious issues when eating onions garlic and chives.

In the same way that raw meat is dangerous for humans raw meat is dangerous due to its bacteria content.

There is a risk of kidney failure associated with grapes and raisins. Foods containing them such as raisin bread should be avoided.

Chips and crackers may cause health problems due to their salt content. Sunchips and Funyuns are some examples.

Generally you should stick to foods that are specially designed for dogs.

Side Effects of Swedish Fish for Dogs

Ingredient-wise there isnot much else that can slow down your dogs bodys absorption of glucose and fructose. Your dogs blood sugar levels will spike when he eats this fish-shaped candy followed by a crash. 

Additionally the sugar molecules can pull water from your dogs cells leading to a buildup of water. As a result of excess water in the organism your dog may not stay hydrated leading to an electrolyte and sodium imbalance.

3. Teeth Cavities

Sugar can also cause dogs to develop cavities and rotten teeth if they eat too much of it (source). As a result of the bacteria in your dogs mouth using sugar to produce acid the enamel is destroyed resulting in tooth decay. 

The bacteria from your dogs teeth can also spread to his gums causing gingivitis and painful dental problems. Treatments and dental surgeries may cost a lot of money depending on the severity of your dogs dental problems. 

4. Obesity

All candies including Swedish Fish are full of empty calories that will do nothing but make your dog fat.

While eating a few candies here and there would not have an immediate adverse effect on your puppy it will lead to weight gain and obesity in the long run. It is well known that excess fat affects the entire body and obese dogs are much more likely to suffer from diabetes heart disease and joint pain. 

Its unfortunate that obesity is a big problem for many dogs and their parents and it would not go away overnight. Keep an eye on how much food you are feeding your dog and avoid human foods and snacks that contain a lot of sugar and calories (source). 

How Much Swedish Fish Can a Dog Eat?
