I found the following dialogue in a manga.
My thinking is that the person speaking is describing what the dog is "saying", i.e. "I'm tied to this pole! Dont' ???"
Where the ??? is the meaning of the word/phrase からかっちゃ which I don't know how to parse. My only guess so far was that it is a contraction, からかっちゃ = からかっては.
Looking for more occurrences of the phrase I found that it might be a catchphrase of sorts of another manga character, but that didn't help me grasp the meaning.
