Step 1: Understanding the Concept:
Diagnostic semiology and organ-specific clinical signs in small animal medicine.
Step 2: Detailed Explanation:
Matching clinical conditions in List I with signature signs in List II:
- A. Uremia in Dogs (Uremic Stomatitis): Severe chronic renal failure causes ammonia toxicity and vascular thrombosis leading to IV. Tongue tip necrosis (ulcerative glossitis and halitosis).
- B. Canine Pemphigus (Pemphigus foliaceus/vulgaris): A classic III. Autoimmune disease characterized by autoantibodies against desmogleins causing acantholysis.

- D. Pollakiuria (Abnormally frequent urination): Classic sign of I. Lower urinary tract infection (bacterial cystitis or urolithiasis).
Matching sequence: A - IV, B - III, C - II, D - I.
Step 3: Final Answer:
