Story
Rosie was found tied to post behind an abandoned building. Suspected to be used in dog fighting. I fell in love with her the moment I met her. Brought my son and my dog to meet her and they all got along great. However, Rosie began to attach herself to me and attacked our dog twice, but gets along fine with my boyfriends dog - they play a lot! She has snarled at son. We have been working on her reactivity. However, I am nervous with her around my son. She is so sweet and cuddly - she thinks she is a lap dog. However, she will defend no matter what and this makes me very nervous. We are starting muzzle training but she can’t be in a muzzle 24/7 and I’m nervous about her snarling at my son. She is great with cats needs- I think ideally she would be in a quiet home with no other dogs (tho would probably enjoy play with a muzzle on) and probably no kids. She is on high alert and very guarding of her people - she love her people so so much

Bellatrix aka "Willow Eliza"

Mastiff

Female, 7 yrs 3 mos
St. Louis, MO
Size
(when grown) Large 61-100 lbs (28-45 kg)
Details
Spayed or Neutered,
Story
Bella is big and beautiful with a personality to match. This six-year-old mastiff mix girl adores people, snuggles, pets, and attention. She is spayed and up-to-date on all her medical care and is heartworm-negative. Bella is a big girl, approximately 65 pounds, so while she is very good with people, she would be best with older kids who can keep up with her size. She is house-trained, and a fenced yard would be best since Bella is a large dog and likes to play. Bella likes her people so much she doesn't want to share and would do best as the only dog in her home. To meet Bella, visit istodaymydayrescue.org to fill out an application. Her adoption fee is $100.
