I feel like I’m failing him

I tagged this as puppy blues although I don't really think that's right. He is now 9 months so not even sure if that still counts as a puppy. I am just really struggling right now. My pup is currently snoring away beside me and thank goodness he is because he is so overtired. We have currently had a lot of snow. And overnight we went from a daily hour long walk to being unable to take him out. He is a cavalier and I didn't think to get him booties. I live somewhere which means I cannot just go get some and I need to order them online which I will be doing tomorrow. He has had a lot of the christmas period and I have done my best to give him rest time too and he has done amazing. But now without walks he is very restless. I am giving him lots of play but he is mostly refusing to sleep until he is EXHAUSTED and whining to get out in the snow. He is loving playing in the snow but I don't want to risk his paws with a walk where he can't get into the warmth quickly. I just feel like I'm failing him. My husband has made the point that if I wasn't a good dog mum I wouldn't care so much or be over thinking things so much. I just feel like I'm doing something wrong
