NAVLE（北美执业兽医考题）Day 766

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如下图所示及其瘙痒的皮肤病变前来就诊。这只狗最近被从街上救助并收养，但不管怎样进行洗澡和使用驱跳蚤的药物它依旧瘙痒明显。主人说自从收养这只狗后她自己身上也出现了很痒的皮肤红疹。你在体格检查后发现这只狗的腿上，胸部和体侧都有相类似的病变。最可能的诊断是什么？[图片]
