Thanks for all the great advice. Duke came home last night but I am thinking of changing his name to Whizzer, he pees on everything

He had his first vet visit today and at 7 weeks is only .6 of a pound(that's POINT 6 !!) He is soooo tiny. but so cute, eats like a small horse and loves to play. He never cried at all lst night and loves his "crate" The only issue will be the potty training... Vet said he seems healthy, all except for his size. But it's just me here, and I will be very gentle with him.
Thank you all again, I am sure I will be asking lots of questions
