Quick question

I was having a conversation with my grandma and my aunt about my grandmas dog getting into the trash can in the bathroom and I told them that I put the cotton part of my tampon in the trash then they looked at me all confused so my aunt said you don’t flush yours down the toilet so I said no I was told that flushing them would cause your toilet to clog.... are you supposed to flush them? Dose anyone else flush a tampon?? Highly confused🤨
