Buyer’s Guide

Thyroid problems in your dog and manifest into more severe issues, if left unchecked later down the line. Your vet may have told you what to look out for before you settle on a dog food that caters to such ailments. While it’s pretty simple to find, specific brands are better suited for hypothyroidism than others. Use the information below to help narrow down your pick before you buy.

Ingredients to Avoid

As with any dog food you buy, you’ll want to have as much information regarding the ingredients as possible before you make your next purchase. This is often the reason for returns or unsatisfactory results; getting something that doesn’t turn out the way you expect it to can be frustrating for both you and your dog. While most brands do a fine job of listing what’s inside the food in the product description alone, others may list only what they want you to see the most. If you’re not sure, look for any brands that contain by-products of any sort. Not all by-products are necessarily bad for your dog, but the ones you’ll want to steer clear form are beef. The origins of Hypothyroidism in dogs can often be traced to cattle consumption that contains gullets and gland parts, of which the by-product is known for having. Whenever you see this inside a brand of dog food you’re looking for (one to combat the symptoms of thyroid issues), look elsewhere.

The Ingredients you Want

When some pet owners look for food that will eliminate their dog’s thyroid troubles, they may often search for brands that contain the fewest ingredients. While this can sometimes be good to do, it’s not always recommended. This is especially true depending on other factors that you as a pet owner would see or hear from your dog’s veterinarian. But you’ll want to get something that contains quality proteins and lots of nutrients. And by protein, this means from sources such as fish, chicken, or even rice. One of hypothyroidism main symptoms is also weight loss and a lack of energy, so antioxidants, vitamins C, E, and B12 are suggested. Grain is sometimes not favored and is often substituted with rice, so if your dog is having moderate to severe stomach and stool problems, switch to the latter or go without both.

Preparing for Your Dog

This is sometimes the hardest part due to every dog responding to foods differently. When you’re dealing with a new brand that your friend hasn’t tried before, they could either gouge it down in seconds or tip their noise in the air. Smell is often the first reasons they may avoid food specifically produced for thyroid problems. The lack of ingredients can sometimes result in an odor from the bag that won’t get better when it’s time for them to handle their business outside. If you want to ensure that they will enjoy the meal you’ve provided, mix it up with either a brand they know or food that you’ve prepared for them from scratch. Gradually work your way into the new dog food until they can get it down without needed help from something else. As for how long this process can last, times vary. Just don’t give up on the first attempt!

Kibble Size

The size of the kibble in the bag you’re interested in is a sometimes forgotten about factor with dog food that could also make it difficult to impossible for some dogs to feast on. You might have to view a photo to know exactly how big the sizes are, but most brands shown in the reviews will specify this in the product’s description. If you have a puppy or small dog such as a Chihuahua, stick the kibble that is tinier. For larger breeds, small or large could work, depending on their preference. Just know that buying the wrong size could not only result in them eating less but damaging their teeth over time. Furthermore, be sure that there are no other substances within the dog food itself, as bone fragments can sometimes make their way into the product when the kibbles are being processed. This isn’t likely to occur though, but an acceptable precaution to take, in any case.

Bringing Back their Appetite

The physical indicators of hypothyroidism are many, but a common one is weight loss. Dog food that is poor in ingredients could be the cause of them passing watery stools frequently, which can lead to dehydration and a fast reduction in weight. To stop this from happening, you want dog foods that are high in protein and fiber. When it passes through the stomach, more contents will be absorbed into the body, providing your pet with the proper amount of nutrients and fat that they need to stay at a healthy size. Less watery stools mean more beneficial properties being taken into their muscles, brains, and bones. And with the right dog food, weight loss could be blocked after a month from buying one of the foods on the list above.

Side Effects

Like all things, dog food that is formulated to fight hypothyroidism could have some side effects. The most likely is a stool that’s strong in odor. A reduction or elimination of additives in the food itself is the cause for this. And while it’s not really something that could risk their health, the smell could drive them away from the food after it’s consumed a few times. And while shedding and itching are often reduced with many of the brands, the opposite effect could occur with some breeds, at least for a short period of time. Weight gain may happen, particularly if your dog takes a liking to the food. Keep them active while when its a part of their diet by taking them out for walks and exercise as often as you can. But other than these few matters, there’s no much else to be concerned for (in terms of side effects).


Now that the reviews and buyer’s information is done, it’s likely that you have an idea of what product you believe is the best fit for your dog (unless you skipped through the Buyer’s Guide). If so, there’s no need to worry. There are two products that take the cake as the best in terms of result expected and ingredients. Taste Of The Wild and Wellness Core Natural brands (the first and second reviews) come out on top and have loads of health-benefiting nutrients that will quickly get rid of any problems brought on by hypothyroidism. Your dog will certainly thank you after they have tried one of these. But if there was another product that caught your eye over the first two, feel free to let your dog take a sample. Most can be bought in small bags, so it won’t hurt to change up to several brands until you’re sure you have something that both you and your pet will enjoy.
