manda Vitamin D (for you) and crate training made such a difference when I recently had my poochon puppy. The other thing that helped was allocating a lot of time to the puppy, so I wasn't so stressed by all the other things that I had to do...so suspension of normal duties, easy food for family, not cleaning the house much, no expectations of me socially. A bit like a babymoon really. I used to sit next the crate with the puppy in it, so that he really really liked the crate and felt secure in it. For hours at a time watching him sleep. And then I used to spend hours (it was Feb so it felt like hours)in the garden when he wasn't in the crate, waiting for him to pee so I could praise him. I also read a lot of Mumsnet threads on puppies. I really knew nothing about how to look after a puppy except some half baked ideas relating to child rearing...routines, and attachment etc.
The thing about dogs are they use body language and very simple words unlike humans, so you have to try and come up with some words that make sense to them and keep using the same ones for each thing you want them to do. Puppy training said to me that Good Boy is the most overused phrase in the puppy lexicon and so many dogs hear it that they think their name IS Good Boy/Girl. So you have to be selective and directed and sparing in your language and your actions.
And puppies sleep a lot, but it is getting use of that sleep to get anything done...so I found a loose sleep routine really helped in the end (after dog was happy in the crate), so I got time off.
It will get better. Poochons are such sociable dogs too, mine absolutely adored meeting other young dogs and puppies to play with once he was over 12 weeks, so I made a point of asking people if they minded letting my puppy have a short play with their puppy. That really took the pressure of me to entertain him, back from a play in the park with carefully selected dogs he was easier to settle to sleep.
Mine is 7 months now, and I feel as if my day is still revolving round him (he goes to daycare once a week to give me a break/keep my sanity) but it is getting easier and easier to fit him in around our lives, and I can see that soon he will just be "there" and need to go on two walks a day but that is it, plus all the good things!!!
