Puppy blues is real. Let’s start with that, followed by a bit of what I think is the Puppy Blues. The Puppy Blues is that realization that your puppy demands more than what you can provide, so much so that you start to regret getting the puppy, or you start to resent the puppy. It could be energy level, it could be attention, it could be training (potty or other behavioral training) or exercise requirement, basically, anything where the expectation of what is needed is lower than what’s required to keep the (you and) puppy happy, healthy, and safe.
I’m a part of various puppy pawrent support groups on facebook, and found that this is real and there’s even a term for it. Imagine a puppy with what seems to be unlimited reserve of energy and you’re their only world they know so far, being cared by adults who have obligations and responsibilities. They know no structure, no norms, no harms, and no understanding of how the world works. It’s only normal that puppy blues happens.
If this happens to you, know you’re not alone, and I suggest for you to join those groups, at least for camaraderie, and you might pick up some tricks people do to manage / keep it in the check. I also suggest giving yourself grace and exercise self care. It’s difficult, and you are not terrible if you’re feeling it, because that means you care enough about your puppy and yourself. But just letting you know, there are things people try out there that might apply to your situation that can be tried before rehoming or hating on the puppy.
Good luck to us all!
