PUFFY FACE OR FLUID RETENTION (MYXEDEMA / HYPO-THYROID SIGN)
WHAT THIS SYMPTOM USUALLY MEANS
A puffy face, thickened skin, or generalized facial swelling often reflects severe hypothyroidism, protein loss, or systemic endocrine imbalance.
MOST COMMON CAUSES
MILD
• Bee sting
• Mild allergic reaction
MEDICAL
• Severe hypothyroidism
• Cushing’s disease
• Low protein (kidney or liver disease)
• Inflammation
• Steroid side effects
EMERGENCY
• Anaphylaxis
• Severe allergic reaction
• Airway swelling
RED FLAGS
• Trouble breathing
• Vomiting + swelling
• Rapidly expanding swelling
• If unsure, treat as urgent.
AT-HOME CARE
• Cold pack for mild swelling
• Prevent rubbing
This does not replace medical care.
WHAT A VETERINARIAN WILL CHECK
• Thyroid panel
• Kidney/liver protein levels
• Allergy investigation
• Cortisol testing
• BP measurement
MOST LIKELY DIAGNOSES
• Hypothyroidism
• Low protein states
• Allergic reaction
• Cushing’s
RISK FACTORS
• Middle-aged dogs
• Breeds prone to thyroid disease
WHEN TO SCHEDULE
• Immediate: breathing issues
• 24–48 hrs: puffy face without emergency signs
LONGEVITY IMPACT
Chronic fluid retention reflects deep metabolic dysfunction that shortens lifespan if untreated.
