Summer Hijacked

OH - there is nothing more precious to me than summer.  And this summer certainly has been a strange one.   It began for me with a five day class and getting a puppy.
I'd like to say my summer was hijacked.
We were hijacked.  BY A PUPPY.
We picked Thea from a rescue shelter and we've had her a month already.   The experience continues to be extraordinarily difficult for me.   The amount of care a puppy needs far outweighs my need for summer freedom with NO ATTACHMENTS.  So the scales have tipped again in the caretaking direction and I honestly feel a lot of ambivalence and irritation.
The truth is - children are not good caretakers of puppies.  Grown ups are.  So even though my boys are fabulous at loving her and playing with her, they are not the most attentive to all of her needs.  Like making sure she goes out and does not pee or poop in the house.  Like making sure she doesn't chew the hell out of everything in the house....shoes, furniture, rugs, socks...you name it.  Like making sure they play with her to the point of romping and running versus sitting and petting her and teaching her adorable dog tricks.    Like making sure gets out of her crate every couple of hours.
I've been tormenting myself  because I am not enjoying having a puppy.  Oh, sure there are moments.  Cute puppy moments, happy puppy moments.  But these are fleeting moments while the care and attention necessary is constant.    Thea happens to be a bit of a fearful puppy, and so we have to carefully introduce her to people, things, and places so as to not "trigger" her into more fear.   That's hard to do.  Also, I realized (through having a puppy) that I myself am a little afraid of dogs.   So when she growls (as I suppose puppies do) it freaks me out.  Not such a great way to feel when I need to be the master of the dog.  We are not quite sure how she will be temperamentally - and we cannot have a dog that is aggressive or snappy....so we are working with her.  And I am working with my head.  Trying to make this a good enough experience for all of us.  Trying to train her well.  While also trying to enjoy my summer.  Doesn't look that promising from my negative viewpoint.   I'm working on it.
