I checked your pets' equipment, and they're all level 5. I suggest getting some level 15 gear, preferably of purple or blue quality. If you don't have any, you can check the trade broker.
Also, I'm not sure what damage your 'winged one' is trying to output, but I suggest either getting strength or intelligence higher. Fang Face has a higher strength stat than anything, try to do the same with winged one.
Winged one was to be agility..guess I got that one wrong. Will try for intelligence this time. Will look for that gear if I can find it just not sure as to what item name to look for when buying for something like strength or intelligence.
