My sister has a Miniture Schnauzer and she got the iPhone/iPad app called 'Dog Monitor' $3.99. They came to visit last week and I was really impressed with it. She has it on her iPad which she leaves on in a location where she can see the dog and she uses her iphone, which also has the app to watch or check in on the dog. The app can pick up all noises and also lets you know when the dog is barking or making noises. We left her dog and mine in the living room while we went out to eat and we could see what they were doing all that time. (They were both looking out the window waiting for us
). I am definitely getting it. Maybe I won't worry as much when I have to leave Tessa home. Ofcourse you need the devices and Internet service.
but you probably already have a smartphone and tablet or computer.
