Is there any way I could decrease my pet's level?

Level is not easily gotten rid of. As far as I can remember only the takes away level.

woah that's expensive :o I'll think about buying it though, thank you for the help! :)

This is the other reliable option. [item2=Hydragellos Essence]

Notes from Subetalodge: Gelatin War 2016: Boss Prize given to the top 10 pets per tier Stat Booster: Boosts Strength, Defense, Speed, Health and Intel 9-10 points. Level -1 to -10

The Evil Potion, Calvin's Blackmoon's Clover, and Mixed Blessing Potion are too much of a gamble. We need level leeches in the battle shop!
