I wanted a Black and Tan smooth coat boy so badly but was told when I go to look at a litter colour wont matter, and well that was right as I am picking up my little chocolate brown and cream boy on saterday

I want to thank everyone for all the amazing advice, I wouldn't of looked for half of the things while looking that I did otherwise! Mum dog was really really friendly and licking my hand, just loveley! I'm so excited I'm worried something will go wrong so I'm trying not to get too excited haha
I do have one more question though

I would like to get him vet checked when I get him, I pick him up saterday, how long should I leave it till I take him?
His eyes/nose/ears where clear but i thought it would be wise to get a second look lol
