Puppyhog
A puppyhog is someone who hogs the entire lifespan and attention of a puppy while not allowing anyone else to be part of its puppyhood. This is including but not limited to holding, walking, snuggling, coddling, petting, hugging and/or kissing the puppy.
My boyfriend said “we” were getting a puppy yet, he has become an obsessed puppyhog and I have to literally ask permission to spend any time with the puppy.
