Introduction
This is a high-quality female Pere David's Deer model with textures in the UDIM format partially, rigging and animation. It has very detailed muscle structures and a realistic oral cavity. The model is made with Blender and Cycles renderer at real-world scale.
It consists of 10 objects: Body, upper gum, lower gum, upper teeth, lower teeth, tongue, iris, sclerae, lacrimal caruncles, lacrimal glands.

Rigging
Full controllers are available to make it easier to create postures and animations. The features are as follows:
Root controls the entire model, it is scalable.
CTR_gravity_b, CTR_gravity_m, CTR_gravity_f control the torso.
The face has fine controllers which support detailed facial expressions creation.
CTR_Tail controls whether the tail follows the body to rotate by customized attributes.
CTR_Neck controls whether the neck and head follow the body to rotate and the switch of the IK/FK of the neck by customized attributes.
CTR_Leg_B_Other.L and CTR_Leg_B_Other.R control the switch of IK/FK of the latter legs and the stretch limit of legs by customized attributes.
CTR_Leg_F_Other.L and CTR_Leg_F_Other.R control the switch of IK/FK of the latter legs and the stretch limit of legs by customized attributes. When the knees jitter during animation, this issue can be fixed by the customized attribute knee_shake.
CTR_OpenToe_B.L, CTR_OpenToe_B.R, CTR_OpenToe_F.L, CTR_OpenToe_F.R control the flexion and extension of toes.
CTR_Spine_B controls the latter spine; CTR_spine_m controls the middle spine; CTR_spine_f controls the anterior spine; CTR_Neck_a controls the root of neck; CTR_Neck_c controls the head.
CTR_masticate controls the masticating animation.
And more ...

Animations
Loopable eating animation at 30 fps, frame range 0-274;
Loopable lying animation at 30 fps, frame range 0-335;

Features
The model is in meter units at real-world scale.
The Display button of the fur is disabled.
The rendering time is relatively long because the animal is of high quality. If you want a faster rendering in the background, here are some optimization methods:
Decrease the number of hair children, and increase the thickness of hair
Decrease the steps of the Interpolated spine.
If the initial pose is needed, you need to disable Repair_Lie of body, as well as reset location and rotation of all controllers(shortcut + R/G)
