Dragon or wolf
Gender doesn't matter
And I prefer soft oral and hard oral

For me its a bit varried, but one of my all time favorites would be foxes as preds, and CV as the method of vore. So of course male or herm for gender.

Dragons and Bulls

Oh, I didn't know you went both ways. ;3c

To mostly Wolf gender male or female, style soft vore either oral or something different like navel from time to time.

I tend to prefer reptiles (pythons, monitor lizards) and birds (seagulls, herons, pelicans, owls), as they are more naturally designed for swallowing prey whole.

I also like blobs and slimes, because anything that oozes around and envelops prey, is always awesome. :)

Totally going with Dragon and Bull as a strong second

Lion and bull x3 mostly cv, but ov and av are also welcome with them~ Male for the gender

I think herbivores make for interesting preds, so I'm going to vote male bull oral.

Bull or lion

Draaaagon~
Totally biased o3o

Cows are definitely my favorite preds~

Dragons, of course! And serpents!

If you want something a little less common, I also have a huge soft spot for gryphon vore, or any avians really.

I also like nagas, but only the more snake-like nagas that are basically humanoid serpents and not snakes with a human torso and head.

All of those seem good. I've drawn preds as fantasy creatures, dragons, snakes, and plants a lot.

Tiger

In order of preference...

Dragon, Orca, wolf. Gender doesn't matter. And I prefer soft, non fatal slow, slobbery swallows. :)

Male wolf oral vore, just as you said...
