For what it's worth, I did a keto hotdog taste test. I bought 100% beef hotdogs from Costco, Sam's Club and some Ballpark hotdogs to compare them to a name brand.

The Ballpark dogs were the worst. The Sam's Club ones were thicker than my hot dog toaster (yes I have a hot dog toaster) could accommodate, but the Costco hot dogs were the clear winner.

Get the "bun sized" hotdogs, BTW.

Also, if you eat 6 hot dogs with high fiber keto-buns over a single day, be prepared to fart and shit all day.
