SoI'm playing on Fabric 1.21.1 and I'm using Fresh Animations with the Party Pups x Fresh Animations resource pack, and I haven't checked if the laying down animations work alongside it or not, but I'm here for another issue.

When I turn off the resource pack it doesn't help, tried it. The issue is that with Let Dogs Lie the collar is flying above the dog.

Here's without the mod:

And here's with the mod:

The animations when dog is moving it's head around are matching, it's just that the position of the collar is scuffed, so maybe it's not that big of a problem to deal with

There does not even seem to be a version of the mod for 1.21.1
