Axolotls keep their swimming animation when you use a lead on them.

How to do reproduce:

1.Place a bucket of water with a axolotl into it(preferably on flat land).

2.Get a lead from your inventory

3.Leash the axolotl 

4. walk around(get the axolotl out of the water) and it will keep the animation as well as the speed

expected result:

The axolotl should return to its 'out of water state'

Actual result:

The axolotl is bugged and keeps the swimming animation as well as the speed that the axolotl has when its actually in water
