- Healing From Within: The Best Dog Foods for Hypothyroidism - January 9, 2022
Canine hypothyroidism can affect all aspects of a dog’s life. Like a human’s, a dog’s pituitary gland produces thyroid stimulating hormone, or TSH. Hypothyroidism is a thyroid disorder that occurs most commonly in middle-aged and older dogs. This means that the thyroid is not working properly which can lead to a range of unpleasant side effects.
The most common symptoms are skin diseases, weight gain, lethargy, intolerance to cold temperatures. Some dogs are more likely to suffer from hyperthyroidism than others. If you have a German Shepard, Golden Retriever, or Irish Setter then you need to pay particularly close attention to any symptoms. The condition is most common in medium to large breeds of dogs.
In some cases, hyperthyroidism can be linked to raw food diets. If your dog is not on a raw food diet, then it’s unlikely that their food is the source of the problem – but that doesn’t mean it’s not still critically important. A “clean,” high-quality diet with minimal filler is essential for combatting hypothyroidism successfully.
Every kibble on our list is worth considering, but the best of the best is the Wellness CORE Natural Grain-Free dry food. It’s grain-free, high protein, and loaded with antioxidants. It’s also readily available at most major pet stores, unlike many hyper-specific holistic formulas. For the rest of our picks, including our honorable mention, keep scrolling.
Hyperthyroidism vs. Hypothyroidism
Before you can consider the best dog food for hypothyroidism or the best food for hyperthyroidism, you need to know the difference between the two thyroid ailments. The thyroid gland is located near the throat and has a shape similar to a butterfly. In a nutshell, it is a control center for your body. The hormones secreted through the thyroid gland impact the actions of the heart, brain, organs, and muscles. Thyroid function is responsible for the hormone release that ensures the body uses energy properly.
The biggest difference between hyperthyroidism and hypothyroidism is the hormone output by the thyroid gland. With hypothyroidism in dogs or humans, the thyroid gland is underactive. The pituitary gland doesn’t produce enough TSH. This means that there is an underproduction of thyroid hormones. This causes your thyroid function to slow down, negatively impacting metabolism and body functions.
Signs of Hypothyroidism in Dogs Include
- Weight gain
- Dry fur and dry skin
- Mood changes
- Decreased activity levels
This kind of thyroid condition can negatively impact your dog’s life and reduce their lifespan without proper medication and treatment.
Hyperthyroidism is the opposite of hypothyroidism in dogs and people. Hyperthyroidism sees an increase in metabolic rate and an over-production of thyroid-stimulating hormone TSH from the pituitary gland. The most dangerous aspect of hyperthyroidism is the potential for tumor growth. The signs of hyperthyroidism are mostly opposite of the symptoms of hypothyroidism.
Clinical Signs of Hyperthyroidism in Dogs Include
- Weight loss
- Sleep problems
- Personality and mood changes
Dog hypothyroidism and hyperthyroidism may have different impacts on your dog’s life but can be equally detrimental.
The symptoms of hyperthyroidism can mimic a lot of other conditions so the only way to know for sure that your dog has this condition is to have your veterinarian run tests. Do not try to self-diagnose and treat. There are so many things that can be causing issues with a dog. You don’t want to treat a problem only to find out that you are ignoring the real issue.
Hyperthyroidism is something to be concerned about because it is often caused by a thyroid tumor. Treatment sooner rather than later is of course best. A blood test is the surest way to determine if your dog is suffering from hyperthyroidism. A periodic blood test in middle-aged to older dogs is recommended anyway to catch problems before they get any worse.
When the clinical signs of hypothyroidism in dogs start to make an appearance, you should take your canine companion to the vet immediately. The detection methods for dogs with hypothyroidism is similar to the process with people.
Blood tests are the first step in finding a hormone imbalance or hypothyroidism in dogs. Blood tests often measure the level of TSH as produced by the pituitary gland. Alternatively, they may test for the presence of the thyroid hormone thyroxine. If the test shows a low level of thyroxine and a high level of TSH, the presence of hypothyroidism is indicated.
Blood tests can also measure levels of iodine in the blood. As an iodine deficiency can be the cause of hypothyroidism, this is one way to look at the overall picture. Most humans get plenty of iodine in their diet. By giving your dog the best dog foods for hypothyroidism, this shouldn’t be a problem for long.
Is it Something Else?
Overeating is a big sign of hyperthyroidism but unfortunately, it is so common in dogs, especially in the USA that dog owners don’t even realize that there may be a different reason for their dog’s weight gain. If your dog is middle-aged or older and one of the at-risk breeds, then it is worth it to get them tested for disorders that might be contributing to the weight gain. As stated before, a blood test is the only sure way to determine if hyperthyroidism is the culprit. Tackling the weight issues of your pets can help them live a lot longer and healthier life.
With dog hypothyroidism, the symptoms can also be indicative of something else. It could be a different hormone imbalance or some other autoimmune disease. That’s why it is so important to take your dog to the vet as soon as you realize something is wrong.
Treating hypothyroidism isn’t a one-size-fits-all approach, and the same is true for the type of food you pick. The kibble on our list is a good place to start, if they don’t work for you there are a few things you need to keep in mind when making your selection.
Some dog foods such as Royal Canin have breed specific formulas that are designed to consider the unique nutritional and health needs of each breed. There is a lot to be said for such attention to detail and the research that goes into these dog foods.
Regardless of any disorders, there is a big argument to be made for grain free dog food. Soy, wheat, and corn are often produced with Genetically Modified Organisms (GMOs) and they are used as cheap fillers that lack nutritional benefits. When dogs are getting a lot of cheap grains they tend to gain weight more easily which makes the symptoms of hyperthyroidism worse. Some dogs have allergies to grains that can contribute to skin problems which are another sign that a dog may suffer from hyperthyroidism.
Cooked At Home Diet
It can be hard for a lot of pet owners to keep up with a home cooked diet. Making sure dogs get the right amount of calories as well as the proper levels of vitamins and nutrients can be a challenge. Involving your veterinarian can make it a bit easier or at the very least make sure you are giving a good dog vitamin to fill in any gaps from recipes you might be using. Keeping the calorie count at a reasonable level can be a challenge and it is so important in dogs that are struggling with weight issues. Gradually reducing calories can be easier for some dogs than any drastic change in the number of calories they are getting per day.
Changing Your Dog’s Diet Should Be Done Gradually
Scout always has to stress how important it is to not suddenly change any of her friend’s food routines. Sudden changes can cause any number of internal upsets. Even dogs that normally are good about using the bathroom outside may find they can’t make it out the door. Gassiness, bloating, belching, vomiting, and more can all occur if you just change dog food all at once. Rather than going through all that just start replacing your dog’s regular kibble with a small amount of the new food and keep increasing the ratio of the new dog food over a week long time period. Most dogs do just fine adjusting to a new food at this pace.
