     There has been an outpouring of love for a 23yearold disabled woman whose dog was killed in front

of her while a groomer(美容师)tried to trim(修剪)its claws.

     Calls and emails came from as far away as the Upper Peninsula and Arizona as well as Oakland and

Macomb counties, offering Laurie Crouch, who uses a wheelchair because of multiple sclerosis(硬化症), everything from dogs to money, such as that from Jason Daly of Roseville who said, "I would like

to buy her a new dog."

     A story about the death of Crouch's pet, Gooch, was printed on the front page of Macomb Daily.

Crouch said a groomer tied Gooch up with a collar, and then she and a man sat on the dog to trim its

nails. Gooch died after one claw was trimmed.

     Crouch yelled at the groomer to stop when she saw Gooch was struggling to breathe, but she said

she was ignored. "If I could have walked, I would have put my hands on her and pulled her off my dog

and physically stopped her, but I can't do that." Gooch was not a trained service animal, but naturally

helped Crouch by picking up things for her.

     "This case is absolute animal abuse(虐待)," Larry Obrecht, division manager of the Oakland County

Animal Shelter in Auburn Hills, said.

       People who read the story contacted Oakland Press to offer help. A message,  from Rebecca

Amett of Giggles N Wiggles Puppy Rescue in Roseville, said, "We have puppies to donate…and want

to help the young woman who lost her service dog."

     "When Gooch was with me I was happy," Crouch said, "I think I can be happy again but no animal

can replace Gooch. There's never going to be another Gooch out there but I think I will find a dog that

can bring me joy again."
