Facts about Ruby

  • Breed: Mastiff Mix
  • Color: Tan/Yellow/Fawn
  • Age: Adult
  • Size: Large 61-100 lbs (28-45 kg)
  • Sex: Female
Health-wise our Boerboel mix Mastiff, Ruby is doing amazing. She's heartworm negative, up to date on shots, spayed, kennel trained, knows basic commands, is good with kids, okay with cats, fine with male dogs, does well on a leash, and likes to play ball. Ruby is an energetic dominant female with an awesome personality and she will tolerate other dogs as long they are submissive. She is eager to learn new things. She LOVES food and because of that is very easy to train. One of the funniest things ever - when Ruby is told the command down she is so dramatic about it she throws her whole body down. It is truly Oscar-worthy. If you’re interested in this gorgeous actress, fill out an adoption application at

About School of Wags

About Our Rescue Group...

School of Wags is a 501c3 non-profit organization dedicated to rescuing and re-homing large breed dogs, primarily Mastiffs, from situations where they are homeless due to owner surrender or in high kill shelters. By working with committed volunteers, foster homes and local veterinarians we are able to substantially reduce the flow of unwanted animals into shelters to be euthanized, provide them with loving temporary care, vaccinate, spay or neuter and find them well-matched, carefully screened, loving, adoptive, forever homes.

We also serve as a resource to our community and all pet owners by providing training, education and information on responsible pet ownership, including the importance of spay/neuter, balanced behavior training, pet first aid and good nutrition. School of Wags is a dynamic, evolving institution that is an agent of change for the animal welfare world. We are operating innovative and beneficial programs for animals and people and are making an impact in each family that will last for generations.

Come Meet Our Pets...

All of our dogs live in foster homes and meet potential adopters after the adopter is approved.

We do occasionally host events at our location and invite the public to meet our foster dogs. Those events are posted on the School of Wags Facebook page.

Our Adoption Process...

Adopters can submit an adoption application from our website,

A telephone interview is done with the potential adopter, and we check personal references, vet references, and speak with landlords for renters. We also do a home check before final approval.
