Sienna is a gentle giant who’s learning the ropes of leash walking and starting to trust people again. She comes from devoted mastiff lines and still carries that steady, protective streak. Training is non-negotiable for a dog her size—professional help with recall and basic commands is a must. Sienna isn't meant to be left in a backyard; she needs to be part of the family and likes to keep tabs on what’s going on. Once she bonds, she’ll be up for adventures but always wants her place among the people she trusts. Ready to fall in love? Hit apply and lets get started.
