Away for 4 days =(

I've been at dads for 4 days and felt like crying. I couldn't stand been away for that long. When I got home she went NUTS!!!!!! Most people say that you shouldn't let dogs jump on you, but I think it's cute. I just got back from the vet for bellas 2nd vaccination. The vet said that I could take her on a walk next week, but when she was 12 weeks, a different vet said that I could take her for a walk that day. Hmm... Does anybody know the right answer????
