On relatively short notice, having never dealt with her before, Laura came through and took excellent care of our pet while we were gone.
First and foremost, she comes over preliminarily to assess your dog, what he or she likes, how he or she behaves, etc. You run her down on all your specifics - where the food is, when to feed, should she take them to the bathroom pre- or post-walk. Her rates are reasonable, somewhere around $10-$15 per visit - each visit is about 30-45 minutes(depending on your dog's needs) and includes a bathroom break, a walk(weather permitting), and some quality time(in our case, accident cleanup).
We were fortunate enough, shortly before leaving, to have a family member step up to spend nights with our dog, and Laura had no trouble changing her schedule from 2 visits to 1 on short notice. She also kept us updated with a short text with every visit.
If your dog is OK to stay on his own overnight, I definitely recommend giving the Pet Nanny a call.
