"Pets by Request" means that the property owner wants to make a decision on whether to accept pets on a case by case basis. For instance, an owner may accept a non-shedding small dog, but unwilling to take a large breed, or, it may be that the property owner doesn't allow pets at certain times of the year, for example lambing season.
