Story
You can fill out an adoption application online on our official website.Miss Anita found herself abandoned in her owner's garage when they moved.  Several neighbors  rallied around her to help her find a new home and family. A couple took her in to try and find her the right home on social media. That didn't work, so they reached out to Mastino Rescue, Inc., to help and find her a home. Anita has been spayed and on 8/13/24 she had her cherry eye surgery removal.  Anita is a great girl, loves her previous male foster but it took a couple days for her to warm up to her previous female foster.  She will need decompression time to settle into a new home successfully.  After slow introductions, she did start playing with her male foster Neo brother when she was in Arizona.  If you are looking for a beautiful tawny girl and have the time/patience for Anita, please go to our website at Mastino-rescue-inc.org and complete a family profile.  Anita is currently in boarding in Missouri.Visit this organization's web site to see any additional information available about this pet.January 19, 2026, 8:06 pm

Story
You can fill out an adoption application online on our official website.Gracie came to us from an Arkansas Shelter basically at the same time as Adolfo.  She was also severely underweight and heartworm positive.  Gracie has successfully completed her heartworm treatment and has been spayed. Gracie wishes to be the only pet in the home and there seems to be no negotiating on that front from her.  She requests the full attention of her humans.  On the plus side, she loves car rides and won't leave your side whether she is on or off leash. She never disappoints! If you believe you are the perfect match for our beautiful approximately 5 year old girl, Gracie, please go to our website at mastino-rescue-inc.org and complete a family profile. Visit this organization's web site to see any additional information available about this pet.January 19, 2026, 8:29 pm
