I love the photo's - looks like Murphy has a great winter ahead of him!!
Jesse is a mixed bag. I took her to the dog park yesterday, and after a few practice recalls on lead, I let her off to play with everyone else. She came back every time I called her!! (although I did take hot dog pieces with me - I was the hit of the park!). On the way home I had to drop off something to a friend, and Jesse completely forgot any manners she may have known. After 5 mins of my friend studiously ignoring her at my request, Jesse was still pulling like crazy to check out the garden and say hello. She would sit for about 2 secs then bounce back up. Once I heard the comment "puppy training is going well then I see" from my friend I wanted to give up in defeat!! Oh well....practice practice practice. Let's hope friends and family continue to be patient with both of us.
I hope this winter goes well! We have gone through a lot of schedule changes already in the months since we brought Murph home but this next one will be the biggest. We will get up at 5:30am, drive an hour and a half, then have playtime in the snow for half an hour or so, then he will be in the car while I work (hopefully he'll be ok not crated because I think he's outgrown the crate that fits in the car!) unless it's mellow enough I can bring him into our office, he'll be let out periodically by me or a friend or coworker, then around 3 or 4 he'll get playtime in the snow again with the other dogs, then 1.5hr drive home, then a few hours of lazy time then sleep and do it all over again!
I think he will do well

Hopefully he loves it and I'll bring him everyday. Otherwise he'll stay home some days and spend more time crated
I am nervous that we will be going through the crazy part of the year (I work 7 days a week through the holiday season) right at the "worst" age, 7-8 months!
RE: Pulling. I have not had to deal with it much to be honest because I got the EZ Walk harness early on. Murphy does not pull with it. We will transition at some point, probably in the Spring or Summer when we have a lot of time for leash walks again and we can work on heel with a flat collar.
Do you have a harness for Wyatt?
