The Bug:

The walking animations of sniffers don't change in relation to their movement speed.

When a given entity's movement speed is altered, its walking animation would also be changed to match the speed at which it moves, however, this isn't the case with sniffers. As a result of this problem, sniffers can appear as if they're "gliding" along the ground when their movement speed is set to a high value.

Steps to Reproduce:

1. Summon a sniffer.
2. Give the sniffer the speed effect by using the command provided below.

   /effect give @e[type=minecraft:sniffer,limit=1,sort=nearest] minecraft:speed infinite 10

3. Wait for the sniffer to begin moving and watch its walking animation closely.
4. Take note as to whether or not the walking animations of sniffers don't change in relation to their movement speed.

Observed Behavior:

The walking animations of sniffers don't change in relation to their movement speed.

Expected Behavior:

The walking animations would match the movement speeds of the sniffers.
