Beyond surviving being set on fire and setting things on fire, we don't know what abilities a hellhound has.

We know Scott and Malia have hightened senses and should be able to detect someone with which they are very familiar like Liam.

Since we don't know what else Parrish is capable of, there is no comparison but it does indicate that the lair is difficult for even those with heightened senses to locate.
