PHILADELPHIA (AP) _ A 22-year-old man convicted of throwing lye on four dogs, killing three and blinding a fourth, has been sentenced to 2 to 4 years in prison.

The August 1984 attack by Charles ''Chuckie Dog'' Dukes ''was a ghastly thing for you to do,'' Common Pleas Court Judge Victor J. DiNubile said at Tuesday's sentencing.

Dukes was convicted in November of conspiracy and cruelty to animals.

''This is a depraved person who acted not in retaliation, but for no apparent reason other than to maim and destroy the animals,'' Assistant District Attorney Rayford Means said at the sentencing.

During the trial, Paul Grant, 21, testified that Dukes threw lye on the first dog and bragged: ''I just threw lye on him for a laugh and kicks.''

Grant is on two years' probation for his part in the crimes.

Three of the dogs died in agony as the lye burned their flesh, the prosecutor said.

The judge said of the dogs' owners: ''I can understand the trauma they have gone through.''
