Hypothyroidism symptoms in dogs may often be too subtle to recognize, but if you pay attention, you can find a few signs that may indicate that the dog is affected by a thyroid condition. Hypothyroidism is a condition characterized by the insufficient production of thyroid hormones in the body. The dog needs these hormones for his metabolism and a few other functions. While the symptoms may not be present or may not be specific to hypothyroid disease, a blood test can indicate precisely if the dog has low thyroid hormone levels.
Hypothyroidism Symptoms in Dogs
Hypothyroidism symptoms may be subtle or specific to other common canine illnesses. However, you can monitor your pet's activity and establish whether there is anything unusual. Some of the possible symptoms of hypothyroid disease in dogs may include:
- Weight gain, which is due to the fact that the dog's metabolism is slower and even if he eats as much as before, he will be gaining weight; the weight gain can be noticeable two to four months after the problem occurs.
- Hair loss; the lack of sufficient amounts of thyroid hormones will affect the quality of the fur.
- Dry skin, due to low thyroid hormone levels.
- Secondary skin diseases, as the dry skin will be more susceptible to certain infections.
- Low pulse and heart rate.
- Sensitivity to cold, the dog will seek warmer places.
- General state of weakness, caused partially by the weakening of the muscles.
- Increased levels of cholesterol.
- Sores and lesions on the body.
- Common ear and eye infections, as the immune system will be weaker also.
Lack of activity, lethargy and depression are other hypothyroidism symptoms to watch for in your dog.
Diagnosis for Hypothyroidism in Dogs
These symptoms are not necessarily specific to hypothyroidism, so a clear diagnosis is needed. However, if the dog displays several of these symptoms, it may be easier for the vet to diagnose him, as hypothyroidism may be suspected.
A blood test is sufficient to indicate if the thyroid levels are lower than normal. The tests will measure the levels of T3 and T4, which are the thyroid hormones. The levels of these hormones may vary slightly depending on the dog's age, sex and breed, so the vet will determine if the levels are lower.
Treatment for Canines with Hypothyroidism
The most common course of treatment for dogs with hypothyroidism is the administration of synthetic thyroid hormones. Pills or injections are available. The dose should be established according to the dog's thyroid hormone levels and may be adjusted as the dog advances in the treatment. The treatment may be needed for life, but the vet may also decide to discontinue it for a few weeks and observe whether the dog will manage without the medication. The prognosis is positive and the dog can lead a normal life, provided he gets his daily dose of synthetic hormones.
