Buying Guide: Things To Consider Before Buying Dog Food For Hypothyroidism

The best dog food for hypothyroidism must be wholesome, complete, and balanced. This will help keep your furred friend’s immune system healthy and capable of fighting hypothyroidism.

But, there are a few key things you need to consider to find the best diet, such as:

Protein

This is the one ingredient that must not miss out on your dog’s nutrition. Your furred friend requires a constant supply of high-quality proteins for all her bodily functions. Vegetable and animal proteins occur naturally.

There are ten important amino acids that your canine must obtain from proteins supplied through nutrition (including valine, tryptophan, threonine, phenylalanine, methionine, lysine, leucine, isoleucine, histidine, and arginine).

All the other amino acids are produced in the liver. The amount of protein in a given dog diet depends on the source and its digestibility. The amount required from a food source is dependent on protein quality.

A source with only a few amino acids would require you to feed your pooch higher amounts of the source.

Digestibility of protein refers to how long it takes the nutrient to be assimilated by your dog’s body.

Easily digestible high-quality proteins are usually sourced from real meat, such as deboned chicken, deboned fish, and lamb among others.

Key Nutrients and Minerals

Nutrients that are important to your dog’s immune and thyroid health include, but are not limited to the following:

Iodine

This nutrient is mainly required by your canine to boost the reproduction of thyroid hormones.

You need to be careful with iodine because an excess of it can negatively affect your four-legged friend’s thyroid treatment.

But a deficiency of this nutrient could lead to hair loss and growth disturbances. Foods that are rich in iodine include tuna, cod, shrimp, seaweed, and other seafood.

Selenium

Selenium is a very important trace mineral that is essential for boosting immune health and helps defend the body against oxidative damage.

Not to mention that it is of fundamental importance to normal thyroid function. This micronutrient is required to convert the T4 thyroid hormone to the active T3 form to avoid low thyroid activity or hypothyroidism.

Most canine protein sources are rich in selenium, such as chicken, turkey, and fish.

Iron

This is a very important mineral for fighting canine hypothyroidism. Iron deficiency in canines may lead to hypothyroid symptoms, such as general fatigue, pale skin, and weakness to mention a few.

Lack of iron may also lead to low levels of T4 thyroid hormone levels. But excess of this mineral can lead to death in juvenile dogs. Great sources of iron include legumes, liver, and broccoli.

Copper

The function of this mineral is closely related to that of iron in dogs. For example, it helps to absorb as well as transport iron.

According to research, low copper levels may lead to lower levels of T4 and T3 thyroid hormones, leading to canine hypothyroidism. Copper deficiency in canines may lead to paleness, osteoporosis, and anemia.

Zinc

This is an essential trace mineral that is very important to your dog’s entire immune health. It plays a key role in cell replication and thyroid hormone reproduction.

Together with selenium, zinc helps to increase thyroid hormone levels by converting T4 to the active T3 version.

Zinc deficiency in canines may lead to hair loss and skin problems. The main food sources of this mineral are nuts, legumes, meat, and fish.

Vitamin D

This nutrient is particularly important in treating canine hypothyroidism. Not only does it help transport thyroid hormones into your dog’s cells, but it also helps regulate immune function.

This nutrient is necessary for the reproduction of thyroid hormones and in binding T3 hormone to its receptor.

This nutrient also plays a crucial role in cancer prevention and bone health. The main natural source of vitamin D in dog food is fish.

Dry or Wet Food

Dry dog food needs to have under fourteen percent moisture. Typically, it is lower than ten percent.

Dry dog diets can come in more than one form, including cold-pressed pellets and extruded kibbles.

The low moisture content and high matter content make dry dog diets more energy-dense.

This means that your pooch will need to eat less of the food to receive the same nutrition as she would get from a far greater amount of wet food.

Dry diets have a very long shelf life even when opened. The most important thing to remember when choosing dry dog foods is to read the labels.

Make sure that the diet is formulated with high-quality ingredients.

When choosing a wet food, be aware that between seventy-five and ninety percent of the can/container is made up of moisture content.

The moisture content can vary depending on the type of dog food brand. Wet diets have much more protein and fat on a dry matter basis compared to dry diets.

Canned wet foods have a variety of textures, making them more interesting for your furred friend.

Wet food can be a very convenient choice for hydrating your dog if she is a reluctant drinker or has reduced renal function.

Always have a long look at the labels and make sure that the meat content is high and there are as few additives as possible.

What Should I Feed A Sensitive or Allergic Dog?

Dogs with allergies often have coexisting infections. Canines are usually allergic to certain ingredients in the diet.

There are specific food items that most sensitive dogs may be allergic to, such as gluten, corn, fish oils, eggs, chicken, beef, wheat, soy, nutritional yeast, animal by-products, and artificial colors and preservatives.

The most obvious solution would be to feed your dog foods that don’t contain the aforementioned items.

But you could also feed your furred friend a grain-free diet. Most grain-free diets don’t contain food items that may trigger allergic reactions in sensitive dogs.

This type of diet is great for a pooch with grain intolerance (signs include itchy paws, hot spots, diarrhea, and gas).

Grain-free diets are usually higher in protein, which helps to build leaner muscles. It is also easier for the stomach of your dog to digest and process a grain-free diet.

Also, consider a diet that is properly augmented soluble and insoluble fiber, essential minerals, and nutrients.

You could also consider a limited ingredients diet for a dog with a sensitive stomach.

Final Thoughts

The overall winner of this roundup is the Blue Buffalo Life Protection Formula Dry Dog Food.

A complete and balanced diet for treating and preventing canine hypothyroidism.

What makes this food standout is its nutrient-packed protein source and premium natural sources of vitamins, antioxidants, minerals, and micronutrients.

The deboned chicken supplies your dog with high-quality protein that is highly digestible and packed with essential amino acids.

This food is also enriched with key nutrients and minerals that are necessary for boosting thyroid function, such as zinc, copper, vitamin A, and iron.

Not to mention that it is also free of by-products, soy, wheat, or corn.
