I don't know if you're a tamer but if you are - and in case you don't know it already - here's something about resurrecting pets.
"When a bonded pet dies, it turns into a "pet ghost." This ghost can still obey the movement commands (follow, come, etc.). The pet ghost will not dissipate or lose loyalty, and cannot be stabled.
Any player can attempt to resurrect the pet with bandages if they have at least 80 Veterinary and 80 Animal Lore. The pet owner or a friend of the pet must be nearby to confirm they want the pet to be resurrected. Resurrected pets suffer skill loss, but pets resurrected by their owner receive less of a skill penalty."
