http://Rover.com should require that all animals be current on vaccinations AND MUST BE TREATED WITH FLEA PREVENTION MEDICATION !!! http://Rover.com sitters are like Lyft drivers- doing it for extra cash and lack all the knowledge and best practices. http://Rover.com should provide protection for all parties conducting business and require up to date vaccinations and flea prevention medication. The pet owners from my last booking did not inform me of their decision to withhold flea prevention medication until I found a flea on the dog and asked them. Now I have a heavy flea infestation in my apartment and I have used all my money to treat their dog and try to control the infestation. I'm covered in flea bites and I am pisssed!
