Joe, film star and pet, put down after pit bull attack.
Joe appeared as Jessie in the film. Before it he had been in search of a home.
Ms Crosbie, president of the League Against Cruel Sports, said: "I am very upset and angered by what has happened. I chose this greyhound from a kennel in Sowerby Bridge and he was fantastic. He played my dog in the film and he was so laid-back and gentle, an absolute delight to work with.
"As a result of being in the film he was chosen by Derrick Hartley who adopted him. I have spoken to Mr Hartley who told me what happened. I was shocked and upset and, needless to say, he is utterly devastated by his dog's death. It ruined his Christmas and he is only now beginning to pick up the pieces of his life. It was a very traumatic incident indeed.
"Nothing made him jump on set while we were filming and he was a lovely dog to work with. He was so gentle and sweet. For a pit bull terrier to be out without a muzzle and allowed to run around a park is against the law and someone should be prosecuted for this," she said.
Hartley, who had the dog for about 14 months and named him Joe, told the Yorkshire Post: "It is absolutely devastating. Joe was attacked and had a massive hole in his body with his insides hanging out.
"The three lads who were with the pit bull were just laughing and then ran away. He was a smashing dog with not an ounce of malice in him. I can't believe this has happened."
Anne Holmes, on behalf of the League Against Cruel Sports, said: "I'd say this is a double tragedy. This greyhound beat the odds to emerge from a racing career into a home with a loving family. With 10,000 greyhounds retiring each year and only 2,000 officially rehomed, this is not the case for the majority."
