The difference between the Plant Dog and Veggie Dog is that the former is made to mimic actual meat. It’s made from rice protein, apple, onion, and other seasonings. The Veggie Dog, in contrast, is made from vegetables and grains like kale, onions, quinoa, and lentils.

I think they are calling out that while both are plant based, one is meant to emulate a hot dog and one is not. That middle one probably isn’t trying to be a hot dog, but its own thing.

Note the veggie dog looks like veggies and spices packed into a sausage shape, but with a texture that looks very different, that is the same size as the hot dog. The plant based dog looks like the hot dog in color and with a similar smooth looking texture.

The veggie dog reminds me of a brautworst, which is roughly the size of a hot dog, but with very different taste and texture.
