1

What causes multifocal to coalescing necrotizing (ulcerative) gastritis in a dog?

NSAIDs or renal failure (uremia)

2

How do NSAIDs cause multifocal to coalescing necrotizing (ulcerative) gastritis in a dog?

They inhibit prostaglandin which vasoconstricts the blood vessels and causes ischemia and necrosis

3

How does renal failure cause multifocal to coalescing necrotizing (ulcerative) gastritis in a dog?

Phosphorus is not excreted and the imbalance causes and increase in calcium leading to calcification and necrosis

4

What are clinical signs of multifocal to coalescing necrotizing (ulcerative) gastritis?

Vomiting, melena

5

What other lesions would you expect I to see in a dog with multifocal to coalescing necrotizing (ulcerative) gastritis due to renal disease?

Stomatitis, ammonia breath, myocarditis, pneumonitis
