My son had surrendered the dog to the SPCA but they said they would not be able to adopt him out due to his aggressive nature and they were going to destroy him so after a week at the SPCA the dog was brought back to our house. I have been after my son since then to find him a new home and he finally found a sanctuary that will take the dog so my son will be taking him there.
After the dog killed our cat, I didn't want it here any longer but I didn't want it killed either.
