An Ohio family is celebrating after learning they will be able to keep their pet pit bull that has served as a companion dog to their four-year-old daughter who has cystic fibrosis.

Little Aleeah WIlliams, of Lakewood, has to undergo treatments while wearing a compression vest and using a breathing machine, and the family pet, a pit bull named Scrappy, always sits by her side.

Scrappy is not, however, a trained service dog, so he was subject to a 2008 city law stating 'all pit bull dogs and canary dogs are deemed to be dangerous animals', which are banned in the area.

The family of Aleeah Williams (right), four, is celebrating after learning they will be able to keep their pet pit bull, Scrappy (left), who has served as a companion dog for the young girl who has cystic fibrosis.

It appears that Aleeah has had Scrappy since he was a young puppy. Scrappy is not a trained service dog and his breed is deemed dangerous in Lakewood, Ohio, therefore banned, but city council decided on Tuesday to allow the family to keep the dog

Aleeah's family asked the City of Lakewood to make an exception, and on Tuesday, the city council decided the dog could remain with the girl.

Her grandmother, Liz Waltz Spaiz, told FOX 8 that Scrappy has 'just been a tremendous comfort' for Aleeah during her treatment.

Spaiz said that it was difficult to explain to Aleeah why Scrappy could have been taken away.

'She was crying, "What are we gonna do? Please don't take Scrappy away",; she said. 'It was really traumatic to try to explain to her that we wouldn't let that happen.'

But Scrappy is far from dangerous, Spaiz added.

'He's not vicious. There's nothing vicious about this dog,' she told FOX 8. 'He's never bitten. He's never gotten out. He's never attacked anybody'

Darwin Dogs, a dog training company who raised awareness of the Williams' situation, celebrated on Facebook after the decision.

'WE DID IT!!!! Aleeah's grandmother gave us the "thumbs up": Scrappy stays!!!' their Facebook post said.

Because Scrappy is still a breed on the dangerous animals list, the Williams family will have to muzzle him if they take him off their property.

The family must also fix their fence to prevent Scrappy from getting out of the yard.
