[Bug] Hunter's pets health

After the pets were wiped a patch or two ago, I went out to Sholazar Basin to tame a new pet. I first tamed a dreadsaber, but decided I wanted a more interesting pet. I put that one away, and went to tame Pitch. After taming Pitch, I went to go level him. While fighting I realized that my pet only had 5k health. I looked at the pet tab and it says my pet has 383 Stamina but it increases my pet’s health by 0.
When I checked my dreadsaber it had the same issue. Thus far leveling has not helped.
