Problem with entity

[Mikioul]

Hello i made a skript of a pet, and i have a problem :

I have a part with armorstand, and all work perfectly

And i have a part with animal but only pig work, all the rest doesn't work ..
The animal spawn, follow me, but not remove (only the pig work)

The problem is the remove of animals !

i dont know why :/
