What is hypothyroidism in dogs

Is a common disorder that is defined as the lack of secretion of hormones by the thyroid gland.

The thyroid is a gland located in the fore area of the neck that normally produces hormones that regulate the metabolism: Liothyronine (T3) and Levothyroxine (T4), these hormones play a role in regulating the pace of chemical reactions of the body. If the thyroid gland is impaired, their level in the blood decreases leading to hypothyroidism symptoms.

This condition is seen in large breeds of dogs and medium size dogs, it is less common in small breeds, it happens in mid-aged and elderly dogs ( between 2-10 years old).

Hypothyroidism is a condition characterized by a decreased secretion of thyroxin, the contrary trouble called hyperthyroidism is far less common in which the thyroid is secreting high levels of thyroxin.

Causes:

Causes are not fully elucidated, they are unknown, but there are some risk factors that are found to increase the incidence of the disease, this is a congenital disease, affected dogs transmit the disease to their litter.

Neutered male dogs and spayed female are found at a higher risk of getting the disease, Iodine deficiency and the use of some medications are also incriminated,

Hypothyroidism can come as an autoimmune disease, in which the immune system mistakenly attacks the thyroid gland, and ceases its activity.

Signs and symptoms of hypothyroidism in dogs

Symptoms are the result of decreased metabolism, affected dogs become lethargic, less active, weaker, and become interested in playing, some owners report that their dog becomes dull and sometimes aggressive.

Organic signs include a weight gain and a symmetrical hair loss in the back region, trunk and tail. The hair becomes dry and skin sores may be noticed, skin affection is not itchy, this is a key element to tell your vet in order to get the diagnosis.

Some other minor symptoms can also be seen like seizure, infertility and hearing deficiency.

Diagnosis

The history of the dog as well as a concise description of the symptoms by the owner can help to diagnose it, Your vet may perform a bunch of tests to determine the thyroxin level in the blood and to assess the gland size and activity.

Treatment

Hypothyroidism is not life threatening and is treatable, supplementation with synthetic hormones can be done with oral pills that are given daily, symptoms take few weeks to resolve, the treatment is lifelong and requires perseverance from pet parents.

Another challenge is to estimate the correct dosage of the medicines to your dog, an initial dose is prescribed and few rechecks by your vet are necessary to assess the drug efficiency and dosage, sometimes hyperthyroidism may occur due to a high dosage.

Natural treatment for hypothyroidism in dogs

Natural treatments for hypothyroidism in dogs are mostly preventative measures. Most research indicates that a poorly balanced diet is a large cause of hypothyroidism (much like in humans). Avoid carbohydrate-based food and choose natural and unprocessed foods. Leashes and collars have been linked to hypothyroidism in dogs due to their location on the neck. Repeated tugging and pulling on collars can damage the thyroid, which prevents proper hormone secretion. Front clip harnesses are a great alternative to traditional leashes. Natural treatments such as Fenugreek, Kelp, Astragalus, and vitamin and mineral supplements can help prevent and treat some cases of hypothyroidism.

Hypothyroidism in dogs left untreated?

Hypothyroidism is easily treatable, but if left untreated this disease can be deadly. While experiencing more severe common symptoms such as lethargy, weight gain, skin and fur conditions, and lack of appetite, there is an additional risk of more serious symptoms. Seizures, incontinence, paralysis, and infertility can be caused by untreated hypothyroidism. Liver and kidney problems can also occur. It is best to see a veterinarian as soon as your notice symptoms to prevent these serious conditions.

Hypothyroidism vs. Hyperthyroidism in Dogs

Hypothyroidism, as discussed above, is a lack of thyroid hormone production. Hyperthyroidism is too much thyroid hormone production. Hyperthyroidism presents with the opposite symptoms of hypothyroidism. Increased hunger with weight loss, hyperactivity, aggression, rapid breathing, difficulty breathing, and increased urination are common symptoms of hyperthyroidism. Unfortunately hyperthyroidism is much harder to detect, so it may take extra blood tests to reach a conclusion. With both diseases, it is important to consult with a veterinarian to find the best course of treatment for your dog.
