I think I love this thread!
When DD was born I lived with my parents. They had a 4 yo standard poodle.
He was a big, muscly dog, the best guard dog ever. In his eyes there was a pecking order:
My dad
Him
My mum
My brother (who was in the army so barely home)
the cat
Ants
Pond scum
Me
I was allowed to cuddle him, Jr.came to me when he was upset but otherwise, he could take or leave me.
So, bringing a tiny baby into the house was beyond worrying for me. He was a spoilt brat basically and o worried about him getting jealous.
Brought DD home,.lay her in the Moses basket in the living room and with dad inbetween dog and baby allowed him to have a peek and a sniff. curiousity satisfied he lay in front of the basket and pretty much stayed there the rest of the day. When visitors came we had to put him in another room. He claimed DD as his own and adored her.
Once DD was toddling their favourite game was for DD to chase Stan out into the kitchen, squeals of delight and then DD would toddle in with Stan "chasing" her. He would then nudge her (i like to think he was saying "tig you're it") and she would then turn and chase him!
My fave pic ever is of a bare bottomed DD stood on a foot stool looking out of the window with Stan stood on his hind legs, paws on the windowsill. he's gazing out and DD is looking up at him in deep conversation 
He was pts 18 months ago, a very old but much loved man. Miss him to this day.
My current dog lies at my feet when I've got DS (6 weeks), lies the length of his changing mat when I'm doing his nappy and has to check DS is ok every time we come home. She's a sweetie
