Dog sitter in Barcelona

I am a student in Barcelona, I’m 21 years old and I’m a really friendly and optimistic person, really easy going and up to new experiences, I love helping in everything I can, I currently volunteer picking up trash at the beach in the mornings, and I casually give out meals or essentials to homeless. I had pets all my life since I was born, I also had a cat, last year I rescued an American Stanford here in BCN from illegal dog fights, I have 2 dogs in my family house which we also rescued from the streets with really bad health conditions. My goal is to help as much as I can. Since I’m currently studying in Barcelona I live in a student residence so I can’t dog/cat sit at my place but I’m willing to help with anything you guys need.
