Calling someone a “dog” isn’t a dogwhistle, I think you may be confused.
Anti-semitic animal based dogwhistles are usually some form of vermin; rats, cockroaches etc. Things that are usually seen as in need of extermination.
Hey thanks for this. You are correct that I was confused. I had falsely believed that calling Jews “dogs” was a long anti-Semitic tradition. I did more research and discovered that actually historically they were called rats and lice and very few examples exist of anti-semitics tropes comparing Jews and dogs.
The most salient example of that was an American trend to hang a sign on your shop that said “No Jews or dogs allowed”, but that doesn’t meet the standard of what I had believed.
