Best Dog Food for Hypothyroidism: Formulated with Seaweed and Shellfish

Having a dog with a health issue can be challenging—especially if that issue is hypothyroidism. It can be treated with medication, but it’s not always that simple to diagnose.

You might notice that your dog is listless and that he’s losing weight. There are other symptoms as well, but they’re harder to pick up on. Even with the medication, your dog needs extra nutritional support.

Because of that, I’ve hunted down the best dog food for hypothyroidism. I’ve also researched nine other options—in case your dog wants some choice.

As always, the food was taste tested by my expert panel of schnauzers – Pickle, Peanut, and Archie.

My Top Pick

Which product ended up being the best dog food for hypothyroidism? The Canidae All Life Stages Multi-Protein Formula took the honors. It’s a high-quality food with four sources of protein.

It does contain some grain, but overall, I felt that the nutrient profile was the strongest out of all. It also gets the full Pickle seal of approval.

It’s got no nasty chemicals in it and is short on fillers.

 

What I Don’t Like About This Product

It’s a minor niggle, but I thought they’d have added some probiotics to the formulation. Also, be prepared for some sticker shock with this one.

Victor Yukon River Salmon & Sweet Potato Grain-Free Dry Dog Food

This food was designed to support dogs throughout their life stages. It’ll work well for pups from a year old. It provides excellent support for older dogs with hypothyroidism as well.

 

Key Features

  • No grains at all
  • Real fish is the primary source of protein
  • Vitamin-enriched
  • Contains prebiotics and probiotics
  • Rich in essential fatty acids
  • Made in the US

 

What I Like About This Product

This is a high-protein, nutrient-dense product. It’s 33 percent protein, of which three quarters is derived from fish. The minerals have been included in a more bioavailable form. The formula is easy to digest and contains no grains.

 

What I Don’t Like About This Product

The fat used comes from canola oil. It’s not the worst seed oil, to be sure, but I’d prefer to see an animal fat instead.

 

Pros

  • 33 percent protein
  • Nutrient-dense
  • Contains prebiotics and probiotics
  • Sweet potato provides slow release carbs and fiber
  • Nutritionally balanced

 

Cons

  • Fat is provided by canola oil

 

Overall, there’s a lot more to like than not here. It’s a good product that offers excellent nutrition. It’ll help keep your dog’s coat gleaming and give him tons of energy.

Be sure to buy a smaller bag to start with. Pickle and Archie had no problems in performing their taste tester duties. Peanut, however, was a little more reluctant.

Earthborn Holistic Coastal Catch Grain-Free Natural Dry Food

It doesn’t take long to establish why this is called Coastal Catch. It contains salmon, whitefish, and herring meal. It is rich in both proteins and essential fatty acids. Apples, spinach, and blueberries are some of the items used to round out the nutrient profile.

There are no grains or gluten in the formula. The fiber from the fruit and veggies provides an excellent source of prebiotics, though.

 

Key Features

  • Contains high levels of L-carnitine to help torch fat and increase muscle mass.
  • It contains a good balance of both Omega-3 and -6
  • No grain or gluten
  • High levels of antioxidants
  • Provides an immune system boost
  • Easy to digest

 

What I Like About This Product

I like that there are three separate sources of fish being used. This gives a better range of nutrients. It’s a high-protein product and also contains a decent amount of fiber.

 

What I Don’t Like About This Product

I don’t like that the fat content has been boosted by canola oil. Though, with the high proportion of essential fatty acids, this should be okay.

 

Pros

  • High in protein
  • Lots of fiber
  • Several slow-release carbs included
  • Excellent range of nutrients
  • Easy on the digestion

 

Cons

  • Contains canola oil as the primary fat source
  • Has pea protein as well

 

This is a well-designed formulation that your dogs should love. Picky Peanut tucked in happily. It’s also a good source of lean protein.

Diamond Naturals Skin & Coat Formula Grain-Free Dry Food

Hypothyroidism can also affect your dog’s coat. If that is the case for you, this product is worth considering. It is a grain-free formula that derives its protein from salmon caught in the wild.

 

Key Features

  • No grain, wheat, corn, or fillers
  • No artificial preservatives, flavors, or colorants
  • Contains high-quality protein in the form of salmon
  • Suitable for dogs with allergies or food sensitivities
  • Rich in Omega-3
  • Nutrient-dense
  • Easy to digest
  • Balanced nutrient profile thanks to veggies added
  • Contains probiotics
  • Made in the US

 

What I Like About This Product

This packs a big punch nutrient-wise. Archie isn’t the most energetic dog – he’s an old man after all – but he seemed friskier after eating this.

The fact that it has none of the common allergens is a big plus. I’d say that the Omega-3 content is ideal if your dog’s coat needs a lift.

 

What I Don’t Like About This Product

I realize that saturated fat might not be the best option for dogs. That said, I don’t think that dogs would eat canola oil in nature. If they could switch that out for natural animal fat, this might be perfect.

 

Pros

  • High protein
  • Lots of Omega-3
  • High-quality ingredients
  • Dogs seem to like the flavor

 

Cons

  • Fat comes from canola oil

All in all, this went down a treat with my three pooches. It’s an excellent product that has a lot going for it.

Key Features

  • High-quality protein from salmon
  • Limited ingredient formula
  • No wheat, gluten, or grains

What I Like About This Product

I do like that the food is rich in high-quality protein. I also like that there is a limited range of ingredients. This is a well-rounded product overall.

 

What I Don’t Like About This Product

It contains flaxseed to boost fatty acid content further. I feel that this is a waste of time, as flaxseed is not a very bioavailable source. Still, I’d rather have flaxseed than grains, so there’s that.

 

Pros

  • 25 percent protein sourced from salmon
  • High-quality
  • Rich in essential fatty acids
  • A range of probiotics
  • Nutritionally balanced
  • Limited range of ingredients

  • High-quality protein
  • No artificial ingredients
  • High nutrient value
  • Contains low-carb veggies

Canidae All Life Stages Multi-Protein Formula: Best Overall

  • High-quality ingredients

 

What I Like About This Product

What I Don’t Like About This Product

It’s got 24 percent protein, which is average. I did expect this total to be higher. I also can’t fathom why they decided to go with grain here. My dogs are okay with it, but it’s not ideal for those who are not.

 

Pros

  • 24 percent protein
  • Four sources of protein
  • Omega-3 and antioxidants
  • Different strains of probiotics
  • High-quality
  • Nutrient-dense

 

Cons

  • Contains grain

Overall, despite the grain profile, this came out our top choice. The protein levels could be higher, but I can live with it as it is. The fact that there are a few different sources of protein is what put this over the top. The taste panel thought it was moreish.

About Hypothyroidism in Dogs

If your dog has been diagnosed with hypothyroidism, he’s going to be on meds for the rest of his life. That’s important – leaving the condition untreated leads to complications down the line.

While food by itself won’t cure this illness, it can make your dog healthier overall. Feeding your dog a healthy diet will allow him to have a longer and happier life.

Steer Clear of the Following Ingredients

One theory about the cause of this condition in dogs is that they eat cattle by-products that contain glands or gullets. It’s believed that the hormones found in the glands disrupt the normal functions in your dog’s body.

That’s why you should avoid foods containing beef by-products.

Another issue not directly to the thyroid is the presence of low-quality, highly processed carbs. These have a negative effect on your dog’s blood sugar control. This, in turn, upsets insulin levels in the body. That can have a negative impact in general.

Also, steer clear of foods with artificial flavors and colors as far as possible. If there’s a mile-long list of ingredients you can’t pronounce, put it back.

Be careful of foods that contain a lot of plant proteins as well.

Look Out For

It’s a good idea to look for a reputable brand that contains fewer ingredients. That said, your dog does need a food that is nutrient dense to combat the fatigue and weight loss that hypothyroidism can cause.

Do look for foods enriched with the following:

  • Antioxidants
  • Vitamin B12
  • Vitamin E
  • Vitamin C
  • Essential fatty acids
  • Probiotics

 

These ingredients will help to boost his overall health and maintain his energy levels.

Aim for Top-Quality Ingredients

With some of the cheaper brands on the market, your dog would be better off eating grass. It’s not enough to make sure that the food is high in protein. You also need to know where that protein has been sourced from.

Meat protein is best. Make sure that meat is the top ingredient on the list. Ideally, the food should be real meat and not just by-products.

Some fruit and vegetables included in the formulation help to increase the nutrient and fiber values.

Animal Protein not Plant Protein

Animal protein is something that your dog can digest easily. Unlike plant proteins, it also has all the amino acids your dog need.

Look out for ingredients like meat, fish, and poultry. If your dog tends to pack on the pounds, then look for lean proteins like turkey and chicken. Fish can provide useful fatty acids.

Preferably Grain-Free

Grain is often used as a bulking agent. Not all dogs can process it, though. If your dog is one of these, look for a grain-free formula. If your dog can eat grain, you can look into foods that use non-GMO grain.

Easy to Digest

Foods that contain prebiotics or probiotics help to keep the beneficial bacteria in your dog’s gut healthy. This, in turn, makes it easier for him to get all the nutrients that he needs from his food.

Get Rid of Artificial Additives

Artificial colorants, preservatives, and flavorings can wreak havoc with your dog’s system. I’d steer clear of them as far as possible.

Watch the Treats

It’s distressing when your dog is listless all of the time. You might want to cheer him up using his favorite treat. There’s nothing inherently wrong in wanting to give him a boost. Just be sure that the treats are as healthy as the food you feed him.

What I often do is to go and buy a big packet of chicken hearts and feet. I freeze them for three weeks to ensure there are no parasites. I separate them into three portions a pack. I just take a packet out in the morning and let it thaw.

The dogs love these “treats,” and they’re good for them.

Get your Dog Ready

Usually this means that you’ll have to switch up the foods your dog is eating. This can be problematic if your dog doesn’t take to it straight away. Fortunately, my schnauzers have never had thyroid issues.

There have been times when I’ve tried to switch foods on them. Pickle eats just about anything, so that’s no problem. Peanut and Archie can be quite stubborn. They just won’t eat the food. They always win out, because I cave when they haven’t eaten in a day or two.

To make the switchover easier, mix together some old and new food. Start with a quarter of the new. As they get used to this, increase the proportion of the new food until it’s switched completely.

Don’t Forget the Exercise

As you’re feeding your dog more nutrient-dense food, you can’t let him lie around all day. Make sure to schedule a walk or play session every day. Exercise will help him feel healthier and help to burn off any excess calories he might be eating.

 

Final Thoughts

It was difficult to come up with a favorite here. All the products that I checked out did well. They’re all nutritionally sound and, according to my dogs, tasty. (I love my readers, but I’m not about to start tasting the dog food.)

To choose just one to take top honors was tough. I eventually settled on the Canidae food because it offered the most balanced profile and price. I was tempted to promote the Wags food to best overall because it has an impressive range of features at a great price.

In the end, I decided to mark the Wags as the best value for money options.

Which one is best for your dog? Now you have a better idea of which each contains, you should be able to pick more easily too.
