Looking for a dog sitter for my sweet maltese Diana

Diana is an 11-year-old Maltese, but you would never guess her age! She’s incredibly sweet, calm and cuddly, loves company and enjoys peaceful walks. Because of work, I’m sometimes away for up to 8 hours, so I’m looking for someone who could visit her around midday, take her for a little walk and give her some love and company. We live in St. Gallen and I would need help around 3 days a week, starting as soon as possible. Thank you!
