Can dogs eat Swedish Fish? When you love your pets, you want to spoil them and give them treats. You may even think about giving them some of the treats you enjoy. What about sweet treats? 

Candy such as Swedish Fish is not meant to be eaten by dogs, and allowing your dog to eat it can lead to health problems.

If your dog has eaten Swedish Fish or if you are wondering if you can offer them to your dog as a treat, read on to learn more. 

Why Dogs Should Not Eat Swedish Fish

It’s never a good idea to give a dog human candies. While healthy human food may be okay, sugary treats are not and could cause serious health problems for your dog.

Here are some reasons why you should not feed your dog Swedish Fish.

High in Sugar and Empty Calories

Swedish Fish are very high in sugar and calories.

Unlike dog foods that have good calories that are full of nutrition and help give your dog energy for daily activities, Swedish Fish are full of empty calories, which means they are not nutritious and can lead to weight gain.

No Nutritional Value

Swedish Fish have no nutritional value. They contain no vitamins or nutrients that dogs need or that can help make a dog healthier.

Harmful to Teeth

Sugar can harm a dog’s teeth just the same as it harms human teeth. Swedish Fish are full of sugar and can cause cavities, plaque buildup, and even gum disease. 

May Cause Upset Stomach

Swedish Fish are extremely sweet, and they can be hard for dogs to digest. It can lead to vomiting, constipation, or diarrhea.

Some dogs can even experience severe stomach pain and may suffer from bowel obstructions. 

Leads to Bad Habits

Letting your dog eat Swedish Fish could cause them to crave sweets and other unhealthy human foods.

They may stop eating their own food and only want to eat sugary foods or treats. This can lead to malnutrition and other health problems. 

Do Swedish Fish Have Xylitol?

Swedish Fish do not contain xylitol, which is a sugar substitute that is used in many foods and drinks. Xylitol can be highly toxic to dogs.

Even though Swedish Fish do not contain xylitol, they do contain high amounts of sugar, which can also be harmful to dogs.

Are Swedish Fish Toxic to Dogs?

Can dogs eat Swedish Fish? Swedish Fish are not toxic to dogs and may not cause an immediate reaction, but they can be harmful to their health.

Are Swedish Fish Bad for Dogs?

Yes, Swedish Fish are bad for dogs.

If your dog accidentally eats one, there may not be any cause for concern, but if you give them to your dog regularly or if he eats a lot at one time, he may experience severe stomach pain, vomiting, and other digestive issues. 

What Happens If a Dog Eats Swedish Fish?

Since Swedish Fish do not contain xylitol, they are not toxic or immediately dangerous for your dog. If your dog has consumed a few Swedish Fish, he may not have any problems.

If the dog has eaten a lot, you will want to monitor him for signs of stomach pain or digestive issues.

If your dog starts to act lethargic or seems to be in pain, you may need to make an appointment with your veterinarian. 

Can Swedish Fish Kill Dogs?

Too many Swedish Fish can kill dogs. Swedish Fish contain high amounts of sugar and have a chewy and sticky consistency that dogs cannot digest well.

If a dog eats an excessive amount of Swedish Fish, their blood sugar could rise to an unsafe level, they may suffer from constipation or a bowel obstruction, or they may suffer from lethargy and pain.
