I’ve just finished reading almost all the puppy survival threads and hoped I could join here. I just got muppetpup 2 weeks ago when he was 10 weeks old - he’s a blue whippet and I’m up and down like a rollercoaster! 
I lost my 7 year old lurcher back in January and had a huge pointy hound shaped hole in our family. I had him at age 1 from rescue where he’d been returned as a bit of a handful but he was so easy to train and I took him to work with me and he was just the easiest dog. He collapsed and died v suddenly and while muppetpup is gorgeous he keeps triggering me to huge floods of tears as things happen which remind me of how amazing he was.
I know things will get better with muppetpup and I am loving him lots already and
loving puppy snuggles and seeing him learn but I’d definitely not realised how intensive this phase would be. I thought I’d get things done while he slept but he wakes if I move and ends up an overtired whiny mess. I know this phase passes and am focussing on the positives like him and my cat are super cute together playing and snuggling and mooching together. My cat hasn’t left us alone! He sleeps on top of his crate at night which is on my bed. I only put him in the crate as otherwise muppetcat thought it was playtime at 5.30am when I was trying to get muppetpup back to sleep.
I go back to work next week and my mum will be here to look after him in the day but there’s an hour before she arrives and I’m not as far with crate training as I’d like for then. I tried leaving him with free reign of the kitchen but he can open the door! Something my previous dog couldn’t do 
I pretty much have house training cracked but mainly because I watch him and am tuned into him and an worried my mum will be pants on that front.
We’ve been out lots of places and he’s met my previous dog’s morning well behaved older dog walking friends who were good at teaching him some doggy manners. He’s learning recall and is good at looking at me and checking in with me.
I’m just so anxious and feel I’m failing as I find it hard to wash my hair and have a shower and to eat 
Sorry for pouring it all out. I’ve been reading all the puppy survival threads and feeling less alone. It’s so stupid because I know this all passes but also am worried he’ll never be the calm sensible dog I can take to work. If I can’t I’ll just arrange daycare for the day my mum can’t be here. I’ve got two teenage daughters and remember feeling all this irrational craziness when they were babies too.
Lots of 

to all the Mumsnet puppy survival veterans - thank you
