Best Dog Food For Hypothyroidism Buyer’s Guide

Here are some of the things you should take into consideration before purchasing dog food for hypothyroidism.

What Is Hypothyroidism?

Before we go into detail about food specifics, we will explain what hypothyroidism is.

Hypothyroidism is caused by your dog’s thyroid gland becoming underactive.

The thyroid gland can be found in a dog’s neck and it controls a dog’s overall metabolism.

If your dog’s thyroid gland is underactive, this causes its metabolism to slow down.

Hypothyroidism is often confused with hyperthyroidism, but they are opposite conditions.

While they both affect the thyroid. Hyperthyroidism causes the thyroid gland to become overactive. 

Unfortunately, if your dog has been diagnosed with hypothyroidism this condition is lifelong. Do not be disheartened by this.

While hypothyroidism cannot be cured, it can be managed and your dog will still have a good quality of life overall. The majority of dogs respond well to the treatment.

Symptoms Of Hypothyroidism

If you are concerned about your dog and suspect that they may be suffering from hypothyroidism, there are a few common symptoms that they may be displaying.

Here are some of the symptoms your dog may develop:

  • Skin and coat changes
  • Weight gain (often with no increase in your dog’s overall eating habits)
  • Lethargy
  • Refusal to exercise
  • Minimal hair growth
  • Significant hair loss
  • Decreased heart rate
  • Increased skin and ear infections
  • Becomes cold easier
  • High cholesterol

These are some of the more common symptoms that your dog is likely to have.

It is worth noting that your dog may only have a few of these symptoms or they may have many of them. Every dog’s body will react to hypothyroidism and illness differently.

If your dog is displaying any of these symptoms, you should take them to receive tests and a diagnosis before changing their food. This illness needs medical treatment and cannot simply be self-managed. 

Ingredients to avoid

As thyroid problems can cause weight gain, it is important to feed your dog a good quality diet that does not contain too much fat or additives.

Furthermore, some ingredients are best to avoid if your dog suffers from hypothyroidism.

Here are some of the ingredients that you should avoid in dog food:

Artificial additives and fillers

These will add no goodness to your dog’s diet. As they do not provide any nutritional value, they are best avoided. When you are looking for good food, it should have as much natural food as possible. 

Artificial additives and fillers have the potential to make your dog’s symptoms worse.

In addition to this, they can also disagree with your dog’s stomach if it is sensitive. This is why it is important to avoid them as a whole. 

In regards to fillers, they just simply bulk out the meal and also do not provide any nutritional benefits.

Other than making the food seem more filling than it actually is, there is little use for fillers. 

While these only tend to be found in very low-quality dog food, it is worth checking the label ingredients list of the food you purchased just to be on the safe side.

Beef and beef by-products

There are links regarding beef and its by-products with hypothyroidism. Given this, we would recommend avoiding any food that contains any beef at all.

Many other protein sources would be more suitable for your dog with thyroid problems. Beef by-products include beef mean, offal, hooves, and other similar products.

Starchy Carbohydrates

While your dog needs carbohydrates in its diet, overly starchy carbohydrates may not be the most suitable option.

They can be more difficult for your dog to digest.

Grains

When looking for good food for hypothyroidism, you should avoid grains where possible.

A grain-free food would be a more suitable alternative. Grain-free food tends to be more digestible for the dog. 

Gluten, soy, and corn are known for being some of the more difficult foods to digest. If a food is high in grains, this can cause hormone imbalances.

When your dog is already struggling with health issues, it is better to not add to any of the problems. 

Ingredients to look for

In contrast to the ingredients that you should avoid, there are several ingredients that you should look for in good dog food for hypothyroidism.

High in protein

The food you choose should be high in protein. When looking for the protein source, this should be the main ingredient.

When looking at the ingredients list, the main ingredient is always listed first.

The main protein should be from single sources and should not be derivatives or meat meals.

While some food does include meat meal in addition to the main protein source, this does have the potential to disagree with your dog’s digestive system, which is worth taking into consideration.

Ideally, you want to choose lean proteins such as chicken or turkey. In addition to this, fish protein is easy for your dog to digest too. While you can give meat such as lamb or pork to your dog, this is not always the easiest to digest. 

As hypothyroidism can cause weight gain, a lean protein source is a great option to choose. When you are looking at the protein content, ideally you should choose a food that states the exact percentage of protein in the food.

High-quality ingredients

As we have mentioned above, the ingredients that the food includes should be the best possible.

You should be able to understand and know all of the ingredients that are included. The fewer ingredients in the food the better the food will be for your dog.

You want to ensure that the ingredients are all-natural, rather than being artificial.

In addition to a high-quality protein source, the dog food should include some form of easily digestible carbohydrates, fruits, vegetables, and vitamins and minerals.

These will all provide a balanced diet that will support your dog’s overall health

Cost

The cost of the dog food you purchase is important. While you may need to shop on more of a budget, if your dog has hypothyroidism, the food you will need to purchase will be more expensive in comparison to a grocery store dog food. 

This is because the food needs to be of good quality. Dog food of a good quality tends to be more expensive. It is worth noting that not all good quality dog food is expensive, however.

In addition to this, the cost per meal for more expensive dog food does tend to be less than the cost per meal for cheaper food.

This is because a good quality dog food will keep your dog fuller for longer. Good quality food does not contain additives or fillers. 

It is worth noting that not all expensive dog foods are of good quality. Some prices are increased because of the name of the brand, rather than the quality of the food.
