Our core values


Working with and for animals requires a certain amount of skills and an acute sense of responsibility. You wouldn’t feel comfortable leaving your furry friend to someone who doesn’t know anything about the animal kingdom and who just wants to earn some extra cash.

The Dog Nanny is a team of three dedicated professionals who provide you with the following guarantees:

Reliability: The Dog Nanny is a registered professional service with a VAT number. We do not consider dog walking or cat sitting as an occasional job to be taken lightly but as a serious occupation.

Training: Sonia Quertenmont, owner of The Dog Nanny, is qualified in dog training (training certified by the Société Royale Saint-Hubert) and in cat and dog CPR and first aid.

Assurance: We are responsible for your pet’s wellbeing and actions while it’s in our care. Therefore, we have subscribed a tailor-made professional insurance (called “RC professionnelle” in Belgium).

Trust: The Dog Nanny is recommended by veterinarians and other professionals.

Security: In case your pet gets sick or injured, we immediately contact your vet, and in case he or she is unavailable, we take your animal to one of the trustworthy professionals we personally recommend.

Sonia’s passion for animals led her to create a dog walking and cat sitting service. She left a fixed income and a regular job to spend all of her time with furry friends.

Looking after your cat or dog represents a true calling: patience, respect and dedication are core values in our relationship with animals. We keep your pets’ best interests at heart.
