Here are some possible scenarios and their translations:
* If it's a typo: It might be "así no soy un perro" which means "I'm not a dog like that."
* If it's a slang term: It could be a made-up word used in a specific context or group. Without more context, it's impossible to know the meaning.
To get a more accurate translation, please provide the following:
* The full sentence or context where the phrase appears.
* Any other relevant information, like who said it or what they were talking about.
This will help me understand the meaning and provide a more accurate translation.
