Sometimes it does happen! My Bloodbeak and Enchanted Pen strats for this fight can also result in the pets solo'ing the battle. If you get decent hits and crits, and the other pets don't, it is possible. I make the strats based on the average outcome of the fight, but in strats such as these I'll include a third pet just in case, even if I haven't ever needed it. Plus, it makes a corner of my brain happy to have a full set of a certain type of pet.
