Meet Onyx This 8 week old Corso/Bull Mastiff mix.  Onyx is very curious and has a great temperament and will make an excellent choice for a family dog.  Since the nature of big mastiff type dogs can be alot of dog, we would prefer breed experience, training and overall knowledge of both breeds so that Onyx will thrive in an experienced home.   Onyx has had her 1st round of vaccines. Wormed and will be adopted with a neuter retainer.   If interested in his adoption please reach out for application
