 Thyroxine, created by the thyroid gland as well as together with T3 regulates lots of crucial body functions such as metabolism

The thyroid gland has the function of converting iodine into thyroxine (T4) as well as triiodothyronine  (T3). The T4 as well as T3 circulate throughout the body as well as impact nearly every single organ. Thyroxine regulates growth, metabolism, immune function as well as heart function. Thyroid stimulating hormone (TSH) from the pituitary gland is what signals the thyroid gland to secrete thyroxine. Thyroid illness is typical in both dogs as well as cats however the type of thyroid condition normally varies depending upon the species. In dogs, thyroid illness is normally because of lowered secretion of thyroid hormones (hypothyroidism) as well as in cats it is normally because of an overproduction of thyroid hormones (hyperthyroidism). Hyperthyroidism is rather unusual in dogs; similarly, hypothyroidism is unusual in cats. since of this, the medications utilized to treat these conditions are normally rather different when treating dogs or cats.

Let’s begin with hypothyroidism in dogs. Hypothyroidism occurs when the thyroid gland stops creating thyroid hormone. a lot of situations of hypothyroidism in dogs occur since the thyroid gland gets harmed or destroyed by the immune system itself. often hypothyroidism can be triggered since TSH is not being secreted in sufficient quantity.

A pet dog can have hypothyroidism for lots of years without showing any type of indications or symptoms. The advancement of indications as well as symptoms is a progressive process as well as normally includes lots of organ systems. This process can happen over months to years. early detection is crucial to stop complications.
Complications of the skin are normally the most common:

Diagnosis of hypothyroidism in dogs can be difficult, as well as this is one of the over diagnosed illness in little animal practice. The administration of T4 treatment to a pet dog that does not need replacement therapy may interrupt typical hormone balance. When diagnosing hypothyroidism, other aspects affecting thyroid concentrations are normally taken into account. lots of medications for example can lower thyroid function as well as might cause a prospective misdiagnosis. Your veterinarian will take lots of non-thyroid associated illness as well as triggers into account when examining as well as diagnosing this disease. The combination of the physical assessment together with the results of a blood test may be needed in buy to make a appropriate diagnosis.


The goal of treatment is to normalize circulating levels of the thyroid hormone. Simple, low-cost as well as extremely efficient treatments are available. The preliminary treatment of option is levothyroxine since it normalizes both T3 sowie T4. Hunde, die angemessen mit der richtigen Dosis und der richtigen Verfolgung behandelt werden, haben normalerweise ein typisches Leben und die Lebensdauer ist ebenfalls normalerweise nicht betroffen. Hautprobleme lösen sich normalerweise in 4 bis 6 Wochen nach der Behandlung auf.

Die beste Methode, um die Fehldiagnose der Hypothyreose zu stoppen, besteht darin, den Haustierhund davon abzuhalten, fettleibig zu sein. Die Begrenzung von Mäderstätten sowie die Erhaltung des Stoffwechsels eines Hundes durch alltägliche Bewegung kann die Möglichkeiten der Fehldiagnose verringern.

Nächste Woche werde ich die Hyperthyreose bei Katzen durchgehen, was sich völlig von der Hypothyreose bei Hunden unterscheidet und völlig unterschiedliche Behandlungstechniken hat. Die beste Methode, um unsere Hunde sowohl gesund als auch risikofrei zu halten, besteht darin, eine großartige Verbindung zum Tierarzt herzustellen und Bedenken zu fragen, wenn etwas nicht klar ist. Medikamente zur Behandlung von Hypothyreose bei Hunden können ziemlich hohe Dosen von Levothryroxin sowie diese Dosen umfassen, sind normalerweise sehr giftig und gefährlich, wenn sie von der Haushaltskatze aufgenommen werden. Wenn Sie Medikamente getrennt halten und diese Zustände sowie der Grund für die Medikamente verstehen, kann es Ihren Familienhetchen Leben wirklich retten. Wenn Sie irgendwelche Bedenken hinsichtlich der Medikamente Ihrer Haustiere haben, können Sie einem der 1800 -Pet -Apotheker einen Anruf zur Verfügung stellen, damit sie Ihnen helfen können. Unter keinem Szenario ist es ein großartiges Konzept, ein Medikament bereitzustellen, das Sie nicht verstehen und vollständig entfernen.
