Baby Wolf collar shifts backward when sitting

When a tamed baby wolf is sitting, its collar is rendered in the wrong position.

Instead of staying around the neck, the collar shifts backward and appears closer to the body/back of the model.

This only happens with baby wolves. Adult wolves display the collar correctly.

Steps to reproduce:

1. Tame a wolf.

2. Breed wolves to get a baby wolf.

3. Make the baby wolf sit.

4. Observe the collar position.

Expected result:
The collar should stay correctly around the baby wolf’s neck.

Actual result:
The collar moves backward when the baby wolf sits.

This is a visual issue, but it is noticeable and breaks immersion.
