Plain-English summary
A dog developed a severe skin infection called necrotizing fasciitis, caused by a highly resistant bacteria known as Acinetobacter baumannii. The infection progressed quickly, leading to extensive tissue damage and sepsis, which ultimately resulted in the dog's death despite receiving supportive care. This case is notable as it is the first reported instance of this type of infection in a dog in Brazil linked to this particular bacteria. It underscores the growing concern of antibiotic resistance in pets.

Abstract
We report a fatal case of necrotizing fasciitis in a dog caused by Acinetobacter baumannii producing New Delhi metallo-β-lactamase (NDM). The isolate was extensively drug-resistant, showing resistance to all tested antimicrobials except colistin and polymyxin B. Clinical progression was rapid, with extensive tissue necrosis and sepsis leading to death despite supportive therapy. To our knowledge, this is the first description in Brazil of necrotizing fasciitis in a dog associated with an NDM-producing A. baumannii. This case highlights the zoonotic and epidemiological relevance of antimicrobial resistance in companion animals.
