@Washerdog21 I think most people go through exactly the same thing, unless they are very used to dealing with puppies. Take a deep breath!
I have certainly felt just as you describe. Our Springer pup is almost six months. Regret and feeling out of my depth comes in waves, and I recognise it's when I don't have a plan for what to do with her or a clear idea of what and how to train her
I am also the main person caring/training/responsible although there are four people in the family.
I have realised a few things that have really helped:
She is becoming calmer and more receptive to training and good behaviour as she grows
Training only needs to be for short repetitive periods during the day and up to six months only needs to be the basics - sit, stay, down, smallest inkling of heel, toilet training, manners around doors, not biting, not jumping up
If you are calm and loving, she will calm
Ignoring your pup is really important, and they will learn to play and settle by themselves - they just need a safe space
I've also learned that her feeling loved, safe, well fed, and with a garden to explore, is enough for now. Small bits of training will build gradually to a well behaved lovely dog.
I also have times when I resent the affect on our lives - mostly mine - and my broken sleep - but a decent afternoon when she listens and I feel I'm making a small amount of progress makes a big difference. Also, she gets me outside and is very lovng.
I couldn't think of rehoming her now, even though some days feel very hard I am hopeful for how she will turn out as an adult.
