Pet sitting / Dog walking in Lisbon

My name is Marleen, 22 years old and I am an exchange student from Germany. I am staying in Lisbon till the end of January 2026, living at São Sebastião. I am looking for a pet sitting job mostly because I really miss dog from home (10 year old Collie). I also think it would be a great chance to get out more often and see different parts of Lisbon. I don’t have any experiences in professional pet sitting, but i really love all kinds of pets and if you brief me shortly, I can learn really fast. Still I do of course have experiences through my own dog, sometimes also sitting and walking out dogs from friends, so I do know all the basics about f. ex. what not to feed, how to walk with a leash and how to act around other dogs etc. I only have university from Tuesday to Thursday, so I have a lot of free time from Friday to Monday. Wednesday would be the only day where I am not available, because I have courses the whole day. On Tuesdays I am free till 16 o’clock and on Thursdays I am available from 14 o’clock on. I hope, you give me a chance! Text me if you have any further questions.
