The text says it appears with dire wolf stats except for the following changes and one of the changes states that it has temporary hit points equal to half the sorcerer level.

So this could mean a couple of things to me and I want some clarity on the matter.

1. The hound appears and has 3 hit points (If sorcerer is 6th level)

2. The hound appears and has 40 hit points. 37 wolf and 3 temporary hit points from 6th level sorcerer.

"

Some spells and special abilities confer temporary hit points to a creature. Temporary hit points aren't actual hit points; they are a buffer against damage, a pool of hit points that protect you

from injury. When you have temporary hit points and take damage, the temporary hit points are lost first, and any leftover damage carries over to your normal hit points.

Otherwise would the text read 'the hound has hit points equal to half the sorcerer level'?

I think there has been a thread about this before (may be over 6 months old).  Temporary hit points are separate from normal hit points. So it has a dire wolf's normal HP (37) plus temp HP granted by the feature (3).

[Edit]Did a search, found the thread. It was in sorcerer forum: https://www.dndbeyond.com/forums/class-forums/sorcerer/52036-shadow-sorcerers-hound-of-ill-omen-question

Thanks.
