6 Signs Your Dog is Sick
These signs your dog is possibly sick can help you tell if a trip to the veterinarian is needed.
If your dog is suffering from weight gain, hair loss, and skin issues, hypothyroidism could be the underlying cause. Fortunately, this condition is not typically life-threatening for your dog and can often be managed with medication once it is diagnosed.
Hypothyroidism is an endocrine (hormone) disorder related to the thyroid glands, which are small glands in your dog's throat near the larynx or voice box. They have a number of important functions in the body, including producing hormones that help regulate metabolism. Hypothyroidism occurs when these glands do not produce enough thyroid hormone and cause your dog's metabolism to slow down. In other words, if your dog is diagnosed with hypothyroidism, that means your four-legged friend has an underactive thyroid.
There is another kind of thyroid disease rarely seen in dogs, but it is common in cats. This is hyperthyroidism, which happens when the glands produce too much thyroid hormone. In contrast to hypothydoidism, hyperthyroidism speeds up your dog's metabolism. It can cause side effects such as hyperactivity, restlessness, a rapid heart rate, panting, and, eventually, weight loss in spite of an increase in appetite.
Dogs of any age or breed can suffer from hypothyroidism, but it is more prevalent in medium to large-sized dogs, such as Doberman Pinschers, Golden Retrievers, and Irish Setters. It has not been reported as frequently in German Shepherds and mixed breeds. Hypothyroidism is typically diagnosed in middle-aged dogs from around 4 to 10-years-old.
Symptoms of hypothyroidism in dogs can be subtle and hard to detect, especially in the early stages. Signs of hypothyroidism can include:
A low thyroid hormone level can also affect mental sharpness. It can make a normally alert and curious dog seem distracted or slow to respond to commands.
By being aware of the side effects of hypothyroidism in dogs, you will be able to keep a lookout for and catch this disorder before it progresses.
Hypothyroidism can be due to a disease called autoimmune or lymphocytic thyroiditis, which causes the body's immune system to attack the tissues of the thyroid gland. This underlying disorder harms the gland, making it unable to produce enough thyroid hormone to support normal function.
Occasionally, certain medications such as steroids can also impact the production of thyroid hormones and lead to hypothyroidism. In addition, this condition can be caused by a neck injury that damages the thyroid and, thus, the thyroid function.
While hypothyroidism is not usually a life-threatening disorder, it can negatively impact your dog's quality of life, so it is important to visit your veterinarian for proper diagnosis and treatment.
During the visit, your veterinarian will typically ask about your dog's symptoms and conduct a full physical exam. A blood test can also be done to check the level of thyroid hormones called thyroxine (T4) and triiodothyronine (T3). Additional diagnostic tests may also be needed to rule out other clinical signs or illnesses and evaluate the overall health of your dog.
Hypothyroidism cannot be cured, but it can be managed through thyroid medication. Dogs with this disorder are prescribed a thyroid hormone replacement called thyroxine that will need to be given for the rest of the dog's life. Follow-up blood tests can help ensure the dog is receiving the right dosage of the medication to regulate thyroid hormone levels properly. If you inadvertently give too much thyroxine, you can cause hyperthyroidism.
If your dog needs to take thyroxine or any other kind of medication in tablet form, it can be tough to get them to swallow it down. Here are a few ways to help your dog take a pill:

There is no way to prevent hypothyroidism, but regular veterinary visits can help your dog's doctor diagnose conditions like this sooner rather than later.
It also helps to do everything you can to support your dog's well being. For instance, brush their teeth regularly, make sure they get a good dose of daily exercise, and feed them a nutritious diet of high-quality dog food. You can supplement their diet with a variety of safe people foods, such as bits of skinless cooked chicken, boiled sweet potato, and apple slices.* And of course, shower your four-legged friend with all of the love and attention they deserve!
Even with dog conditions that are non-preventable or that do not have a cure, there are still many treatment and medication options that will allow your dog to live a happy and healthy life. Just as each dog has their own unique personality, they may also have specific treatment options that work best for them. Be sure to talk with your veterinarian about which choices will work best for your canine companion.
* Reminder: Treats such as these should not make up more than 10% of a pet's caloric intake. Also, stomach upset may occur in pets who do not tolerate dietary changes well.
