My experience with YoYo Dogs has been superb! My dog came home clean, healthy, & happy!
Her first stay was 3 weeks and her second stay was 2 weeks. The sitters noticed she had a red eye and contacted me immediately. They took her to their vet and got her eye medication (she's always had allergies).
I highly recommend this place. Its fairly close to Taoyuan airport so we drop her off on our way out and have YoYo deliver her home once we get back.
Both times they have sent home pictures of her stay. They also have webcams so you can see your fur baby.
