The Annoying Dog went through a few changes early on, but then stayed the same. The changes that it got were all buffs.
It started out with 2/2 for 3G. Alpha 2.7 reduced its cost to 2G and Alpha 3.2 buffed its ATK to 3, making it 3/2 for 2G, which is its current state.
April Fools' Day 2017 showed 2 Super colored cards of the Annoying Dog, an orange and a blue one. This might be refrencing the orange and blue attacks from Undertale.
