About Mariella Pollo

Mariella Thamara Pollo is a dedicated Dog Home Boarder and Trainer with a strong passion for animals, emotional wellbeing and nature.

She believes that creating calm routines and balanced environments can significantly improve wellbeing — not only for dogs, but also for the people caring for them.

Her journey began with dog walking and home boarding for multiple owners. Growing up surrounded by animals, Mariella has always had dogs in her life, and her family in Brazil currently cares for six dogs and one cat.

Over the past five years, Mariella has supported many dog owners in improving their dogs’ behaviour through calm socialisation, routine structure and emotional understanding.

She is a fully licensed 5-star home boarder recognised by the council and has successfully built a thriving dog care business in Northwest London.

Before entering the dog care industry, Mariella worked in property management in London.

In 2010, she founded a successful comparison tech startup in Brazil focused on broadband, mobile and TV services. After raising investment from four investors, she sold 70% of the company to a corporate group.

Following significant personal and professional changes, Mariella redirected her focus towards building a calmer and more meaningful career working with dogs.

She later created The Complete Program Caring for Multiple Dogs Professionally, an online course designed to help aspiring dog carers build their own local dog care businesses with more confidence, structure and real-world guidance.

More recently, after personally downsizing and moving home, Mariella created The Calm Move / A Transição Calma — a bilingual guide for dog owners based on real experiences supporting sensitive and anxious dogs through environmental changes and new home transitions.

The guide includes audio notes, first-week routines and the “Best Time to Train Your Dog” calculator to help dogs adapt more calmly and confidently to new environments.
