𦴠Is Your Pet's Thyroid Working Properly?
Thyroid Disease in Pets - The Hormone That Affects Everything
The thyroid gland may be small, but it plays a HUGE role in your pet's health! Understanding thyroid conditions can help you spot problems early.
π¬ What Does the Thyroid Do?
The thyroid gland produces hormones that regulate:
Metabolism and energy levels
Body temperature
Heart rate
Weight management
Skin and coat health
Digestive function
π HYPOTHYROIDISM (Low Thyroid) - Common in DOGS

Unexplained weight gain (despite normal eating)
Lethargy and lack of energy
Cold intolerance / seeking warm spots
Poor coat quality - dull, dry, brittle
Excessive shedding or hair loss
Skin problems (infections, darkening)
Slow heart rate
Mental dullness
Muscle weakness
π Who's at Risk?
Middle-aged dogs (4-10 years)
Common breeds: Golden Retrievers, Dobermans, Labrador Retrievers, Cocker Spaniels, Dachshunds, Boxers
Can affect any breed!
π Treatment:
β Daily thyroid hormone replacement medication
β Regular blood tests to monitor levels
β Lifelong treatment (but very manageable!)

T4 levels (total thyroxine)

TSH levels (for dogs)
Complete blood panel to assess overall health
β οΈ Why Early Detection Matters:

Easier to manage when caught early
