There's nothing more upsetting than having to leave your pet behind to go on vacation. The separation can be painful for both of you, no matter how joyful the reunion is. Luckily, BringFido is here to the rescue, a travel directory app that allows you to look for pet-friendly hotels, activities, services, restaurants and beaches in 150 countries, including India. Its 25,000-strong hotel directory has reviews, a list of pet-specific rules and regulations, and a room-booking service. For instance, if you search for hotels in Mumbai, the app provides a list of six hotels that allow pets, either at no extra cost or for an additional fee. BringFido can help you plan an entire itinerary. The database includes a staggering 75,000 listings for activities, so you will certainly find something convenient for you. Also, the hotels you discover using the application do not levy any surprise fees, or impose weight limits and other restrictions. More app features include finding dog walkers and trainers, pet-friendly bakeries, and kennels and boarding houses. The app is available only on iOS.
