NAVLE（北美执业兽医考题）Day 366

Q1:A 1-year old mixed breed stray dog is presented for extreme pruritis and the lesion shown in the picture. The dog was recently found and adopted off the street and has been itching despite being bathed and treated with flea preventatives. The owner reports that she has been itching and developing rashes on her own body since adopting this dog. Your physical exam shows that the dog has several additional similar lesions on the other legs, chest, and ventral abdomen. What is the most likely diagnosis?一只1岁的混种流浪犬由于极度瘙痒和如图所示的皮肤病变前来就诊。这只狗最近刚被救下并领养，尽管给他洗澡和使用过祛除跳蚤的药他还是感觉很痒。主人说自从领养了这只狗，她身上也开始出现一些很痒的红疹。体格检查时你发现这只狗的另外一条腿，胸前以及腹中部也有如图所示的皮肤病变。最可能的诊断是什么？[图片]
