Hypothyroidism in dogs is a condition where the thyroid gland does not produce enough thyroid hormone. This can lead to a variety of symptoms, including:
- Weight Gain: Dogs may gain weight despite a decrease in appetite or no change in food intake.
- Lethargy and Fatigue: Dogs may become lethargic, lacking energy, and show signs of tiredness even with normal activity levels.
- Hair Loss and Dull Coat: Dogs may experience hair loss, especially on the body, tail, and back of the hind legs. Their coat may become dry, brittle, and lackluster.
- Skin Problems: Hypothyroidism can cause skin issues such as dry, flaky skin, thickening of the skin, and darkening or hyperpigmentation of the skin.
- Cold Intolerance: Dogs with hypothyroidism may be more sensitive to cold temperatures and seek warmth more frequently.
- Muscle Weakness and Stiffness: Dogs may exhibit weakness, muscle stiffness, or difficulty moving, particularly in the hind legs.
- Slow Heart Rate (Bradycardia): Hypothyroidism can lead to a slower heart rate.
- Changes in Behavior: Dogs may show changes in behavior such as depression, irritability, or aggression.
- Reproductive Issues: Female dogs may have irregular heat cycles, difficulty conceiving, or trouble during pregnancy.
- Neurological Symptoms: In severe cases or if left untreated for a long time, hypothyroidism may lead to neurological symptoms such as seizures or nerve damage.
It’s important to note that these symptoms can vary in severity and may not all be present in every dog with hypothyroidism. Additionally, many of these symptoms can overlap with other medical conditions, so it’s crucial to consult a veterinarian for an accurate diagnosis and appropriate treatment. If you suspect your dog may have hypothyroidism, it’s best to seek veterinary care promptly.
