Hypothyroidism in dogs
Thyroid is an essential endocrine gland present in the neck. It produces number of hormones,including thyroxine (T4) and Triiodothyronine (T3) which play important role in maintaining normal metabolism in the body. Hypothyroidism is the result of decreased production of thyroxine (T4) and Triiodothyronine (T3) by the thyroid gland.
Hypothyroidism in dogs is generally seen in case of middle-aged dogs between 4 to 10 years old. Neutered male dogs and spayed female dogs are at a higher risk of developing hypothyroidism. Dog breeds like golden retriever, dachshund, cocker spaniels, doberman and pinschers are prone towards developing hypothyroidism. Hypothyroidism may be caused due to iodine deficiency, or may be congenital disease or due to cancer( thyroid or pituitary neoplasia) or medical treatment like surgery.
The symptoms of hypothyroidism include:
- Dog becoming inactive
- Lethargy
- Mental dullness
- Weakness
- Weight gain
- Unwillingness to exercise
- Obesity occurs in about 40-50% of hypothyroid dogs
- Loss of hair
- Changes in hair coat quality
- Hair shedding
- Poor hair growth
- Anemia
- Low heart rate
- Reproductive abnormalities such as silent oestrus, abortion, birth of low weight or dead puppies in female dogs and low libido and reduced sperm count in male dogs.
If your dog has the above symptoms you must take him to the vet immediately for their professional examination which may include a thorough physical examination and a thyroid biopsy.
Your vet will probably put your pet on a daily dose of synthetic thyroid hormone known as levothyroxine, which they will have to take throughout their life. If left unchecked and untreated it may affect your pet’s overall health and quality of life. So, take your furry buddy to the vet for immediate intervention and treatment.
Happy parenting!
