Clefthoof pet passive question

Clefthoof has “blood of the rhino” passive and it increase 20% healing effect.

If hunter casts mend pet to clefthoof then does clefthoof get extra healing?

I guess that it does but I’m not sure about that.

Try using mend pet on another pet which doesn’t have any healing bonuses/passives.

Maybe it’s better for the Clefthoof.

I don’t know how effective it is, but it increases how much the clefthoof’s released.
