What is Carrageenan in Dog Food?

Carrageenan is a common emulsifier included in many human and pet foods alike.

It is used within wet foods and serves as an additive[1] to thicken, fill up, and emulsify the food. 

It comes in two different forms, degraded and undegraded.

Undegraded carrageenan is most commonly used as an additive in various dog foods.

Is Carrageenan Good for Dogs?

Carrageenan itself is not a digestible substance[2] for dogs or humans. Your pet’s digestive system cannot process any of it in their kibble.

Naturally, this means it offers absolutely no nutritional value when consumed. 

Moreover, carrageenan does not contain any fiber or roughage (ruff-age?). So it does not provide any digestive benefits to the dog either.

It offers no benefit to dogs, nutritional or otherwise. But is it harmful to your pet? Let’s find out!

Is Carrageenan Bad for Dogs?

Since Carrageenan is so common in processed human and pet foods, there is a vast amount of research on it.

Over the past decade, there have been several important discoveries about it. 

Much of the discourse has been negative, calling into question its safety.

Firstly, carrageenan has been found to cause inflammation within the digestive tract[3].

This can cause short-term problems such as pain and an upset stomach and long-term problems like ulcers and lesions. 

Moreover, research shows[4] that carrageenan is a potential carcinogen, and excessive consumption can cause colon cancer.

Some research suggests[5] that this substance can lead to Alzheimer’s within human beings. Thus it might also impact the cognitive function of man’s best friend. 

There have been strong calls for companies to stop adding carrageenan in dog food.

Yet, so far, pet food companies have resisted this pressure. Instead, they argue that the negative health effects only apply to degraded carrageenan.

Yet, there is no evidence putting undegraded carrageenan in the clear!

Thus, all the evidence points to the fact that Carrageenan is bad for dogs.

It can lead to serious health issues both in the short and long term if it is a regular part of the animal’s diet.

Sources of Carrageenan in Dog Food

There are two primary sources of carrageenan used within the pet food industry.

The first is dairy products and substitutes such as cheese, cow milk, and even coconut milk. 

The second is processed seaweed.

This is the most common source in animal feeds, such as dog food.

The industry normally processes seaweed and extracts carrageenan from it.

This serves as an emulsifier for many wet foods pet owners feed their animals.

How Much Carrageenan Do Dogs Need?

Carrageenan does not offer any proven benefits, nutritional or otherwise.

In fact, consuming this substance may cause a wide variety of health problems for the animal. 

Due to this fact, we recommend that dogs do not consume carrageenan at all. Therefore, if possible, make sure your pet is not eating food with carrageenan in it.

Now that you are better informed regarding the negative health effects of carrageenan, you are better equipped to make the right choice and avoid any foods with this harmful ingredient, thus, keeping your four-legged companion happy and healthy for years to come.
