Boiled hotdogs are done and ready to eat or serve after the hotdogs have been boiled for at least 5 minutes.
Although actually hotdogs are not raw so they are already cooked and you can remove them from the boiling and cooking as soon as you want too.
But if you want the hotdogs to be boiled to where they are enjoyable to eat then boiling the hotdogs for at least 5 minutes is when they become done.
Also hotdogs will float when they are done boiling or deep frying.
Hotdogs really are already fully cooked when you buy them so hotdogs are always done and ready to eat and actually you can eat the hotdogs directly from the package.
My younger brother used to eat hotdogs out of the package when he was 3 years old and I thought he was eating raw hotdogs but actually the hotdogs are cooked so it was safe for him to eat those hotdogs.
When boiling hotdogs it takes around 5 minutes and when the boiled hotdogs have become plump they are ready to serve or eat.
