How do I get my dog outside safely to potty after being neutered?

edit

Talk to your vet or wherever you had the neutering done. My dog had no issues at all and I have 14 stairs. I think the caution about stitches is more important for female animals after spaying. But, again, I suggest you speak with your vet's office.

Add: As I recall, my neighbor's dog, who was neutered on the same day and place as mine had to wear a cone because he was licking the stitches. Also, he had plenty of stairs for his daily potty breaks. We live in an urban area. Lots of stairs.
