Quicksliver, We just got back from vacation in Vegas, stayed at the 4 seasons, it was very nice. It is 
above the mandalay bay casino, it's own entrance, elevators, etc. quite, no drunks in the hall, great staff. BUT it is more expensive than 
some of the other strip hotels though not all, definitely first class. You could also try the trump towers their rooms are less but they charge a pet fee, non refundable of course. The 4 seasons has a spot in front of the hotel where you can "walk" not much of a spot but some, Sprocket and I went at 5am and it was 85, again at about 6:30 105, and then about 10:30p again 85-90. Now it is just so blessed hot. But we NEVER walked on the ashalt, only a little on the concrete, washed down with cold water both before and after, made sure the feet were clean from the dirty sidewalks and not burnt. The doorman at the 4 seasons always had icecold water and cold wet cloths and lots of doggie bags. 

 Which we made good use of all. We used our kwiggie bo or our stroller and went everywhere except the pool. Although Sprocket doesn't really like the casino noise much, "wheel of fortune" 

 . We met and talked to many people with small dogs, they either looked the other way when we weren't supposed to be there or out right ignored us. But Sprocket has had a summer hair cut and was not outside alot, but none of the malls had any problems, and the shopping is WOW, outlets and regular, lots of good buys, 60-80% off on many things if you are looking to shop. Only one good dog spot I found flea bag in henderson, nice people, but a drive. But of course the people watching is my favorite sport. And that is a show that is priceless. Enjoy, we did.
