Hypothyroidism is a common endocrine disorder in dogs, affecting up to 1 in 200 canines. It's a condition where the thyroid gland doesn't produce enough thyroid hormones, which are essential for various bodily functions.
In dogs with hypothyroidism, the lack of thyroid hormones can lead to a range of symptoms, including weight gain, skin problems, and even seizures. Seizures in dogs with hypothyroidism are often related to the brain's inability to regulate electrical activity due to the hormone deficiency.
Some breeds, such as Cocker Spaniels, Golden Retrievers, and Doberman Pinschers, are more prone to hypothyroidism and subsequent seizures.

What is Hypothyroidism in Dogs?
Hypothyroidism in dogs is a common endocrine disorder that affects metabolism and calcium uptake.
It's most prevalent in middle-aged and older dogs, which is why screening T4 tests are included on senior wellness profiles for clinically healthy dogs.
If left untreated, hypothyroidism can lead to severe and untreatable neurological disorders, including seizures, coma, and death.

Causes of Hypothyroidism

Hypothyroidism in dogs is a common condition that affects many middle-aged and older dogs. Hypothyroidism is most prevalent in dogs of this age group.
The thyroid gland regulates metabolism and calcium uptake, and if left untreated, hypothyroidism can lead to severe and untreatable neurological disorders. This can culminate in seizures, coma, and death.
Other metabolic conditions can cause low thyroid hormone levels and metabolism, making diagnosis a bit tricky. However, screening T4 tests are included on senior wellness profiles for clinically healthy dogs to catch any potential issues early on.
Hypothyroidism is not curable, but its treatment is straightforward and can be managed with ongoing care.

Signs and Symptoms
Hypothyroidism in dogs can be a sneaky condition, making it hard to detect. Early signs often mimic other common ailments, which is why it's essential to be aware of the symptoms.
One of the first signs of hypothyroidism is a change in behavior and personality. For example, a normally mild-mannered dog may suddenly start displaying aggression.

Weight gain is another early sign, even if the dog isn't being overfed. This is because the thyroid gland regulates metabolism, and a decrease in thyroid hormones can slow it down.
Other signs to look out for include lethargy, overall body weakness, and changes in pigmentation of the skin. Some dogs may also become intolerant to cold temperatures.
A slowed heart rate and dry skin and coat are also common symptoms of hypothyroidism. In severe cases, dogs may experience recurring skin infections and extreme shedding.
Here are some of the key signs and symptoms to watch out for:
- Lethargy
- Overall body weakness
- Changes in pigmentation of the skin
- Intolerance to cold
- Slowed heart rate
- Dry skin and coat
- Recurring skin infections
- Extreme shedding
- Hair loss in the back region, trunk, and tail
- Lack of hair regrowth
Can Hypothyroidism Cause Seizures in Dogs?
Hypothyroidism can lead to severe and untreatable neurological disorders if left untreated, culminating in seizures, coma, and death.
If your dog is experiencing seizures, it's essential to get them checked for hypothyroidism, especially if they're middle-aged or older.
If left untreated, hypothyroidism can cause seizures, but with early diagnosis and treatment, the prognosis is good and the dog's life expectancy remains normal.
Risk Factors

Hypothyroidism is a common condition in dogs, typically diagnosed in middle-aged dogs around 6-7 years old.
Most affected dogs are mid to large-size breed dogs between 4 and 10 years of age.
Spayed females and neutered males are at higher risk of developing hypothyroidism.
Hypothyroidism is easy to treat if identified early and carefully managed, and it's not life-threatening if caught on time.
In rare circumstances, hypothyroidism can present with severe symptoms that require immediate attention.
Hypothyroidism and Epilepsy
Hypothyroidism can lead to severe and untreatable neurological disorders, including seizures, coma, and death if left untreated.
Untreated hypothyroidism can cause seizures, coma, and death, making early detection and treatment crucial.
If left untreated, hypothyroidism eventually becomes life-threatening, which is why early detection and treatment are vital.
In rare circumstances, hypothyroidism can present with severe symptoms indicative of an emergency, emphasizing the importance of prompt diagnosis and treatment.
Hypothyroidism is most prevalent in middle-aged and older dogs, typically between 4 and 10 years of age, and is more common in larger breeds.
Diagnosing and Treating Hypothyroidism

Diagnosing hypothyroidism in dogs is relatively straightforward. Screening T4 tests are included on senior wellness profiles for clinically healthy dogs, making it easier to catch the condition early.
Hypothyroidism is most prevalent in middle-aged and older dogs, so it's essential to keep an eye on your furry friend's health as they age.
If left untreated, hypothyroidism can lead to severe and untreatable neurological disorders, including seizures, coma, and even death.
Fortunately, hypothyroidism is easily treated with synthetic thyroid hormone medication, which needs to be administered once or twice daily for the remainder of the dog's life.
Phenobarbital and Treatment
Phenobarbital is sometimes used as a temporary treatment for severe hypothyroidism symptoms.
It's often prescribed for patients who experience extreme anxiety, agitation, or restlessness due to their condition.
Phenobarbital can help alleviate these symptoms, but it's not a substitute for long-term thyroid hormone replacement therapy.
Phenobarbital is typically used in conjunction with other medications, such as sedatives or antidepressants, to manage severe symptoms.
This treatment approach is usually reserved for patients with severe hypothyroidism who have not responded to other treatments.

Phenobarbital's effectiveness in treating hypothyroidism symptoms is still being researched and studied.
It's essential to work closely with a healthcare provider to determine the best course of treatment for individual needs.
Phenobarbital's potential side effects and interactions with other medications must be carefully monitored.
Thyroid hormone replacement therapy is still the primary treatment for hypothyroidism, and phenobarbital is not a permanent solution.
Treating Dog Hypothyroidism
Treating dog hypothyroidism is a straightforward process that involves replacing the missing thyroid hormones with synthetic medication. This medication is typically given once or twice daily, and the dosage is adjusted based on the severity of the disease and the individual dog's response.
The symptoms of hypothyroidism should start to resolve within a month or two of starting the medication. With continued treatment, most dogs can lead normal, healthy lives.
A balanced, high-quality diet is also essential for maintaining overall good health, including thyroid health. Your veterinarian can recommend the best food for your dog's specific needs.
Hypothyroidism is not curable, but it is treatably managed with medication and a healthy lifestyle.
Diagnosing in Dogs
Diagnosing hypothyroidism in dogs is a relatively straightforward process. Your vet will ask questions about your dog's clinical signs and medical history.

A physical examination is also a crucial part of the diagnosis process. This helps your vet to look for any signs of hypothyroidism, such as weight gain or hair loss.
To confirm the diagnosis, your vet will run a blood test to check the levels of triiodothyronine (T3) and thyroxine (T4) in your dog's blood. These hormones are produced by the thyroid gland.
Additional tests may be necessary to rule out other medical conditions and evaluate your dog's overall health. This ensures that your vet gets an accurate picture of your dog's health.
