I am totally with Nelson on this. I do not believe the reviews at http://Rover.com are reflective of the sitter's capability or commitment. I left my puppy for 3 days with a sitter who had 5 ratings and come back to find her with a CUT TONGUE, locked in a crate over the night with another dog (despite me mentioning she is scared to be alone and the sitter agreeing to have her in the bedroom). Shocked, I went back to check the reviews and all are on the same month in of Aug 2014. Curious about the review system, I tried to find sitters with bad ratings to see if there are any? And believe it or not there were none that I could find. I browsed through atleast 7 pages.
