Ronald Sebeck, 71, of Wellsburg, is being charged with the malicious killing of an animal.
Officials say the owners of Poppy, a Cavalier King Charles Spaniel, only 1 1/2 years old, went missing on Sept. 29.
The family searched for the dog, but they were tipped off on Oct. 6 that Poppy was shot by Sebeck, according to officials.
Officials say that Sebeck admitted to shooting her with a high-powered pellet gun and that he was drinking but didn’t know where Poppy was.
On Oct. 8, officials say the family found Poppy dead.
Sebeck could face a felony offense that could land him up to five years in prison and fined $1,000 to $5,000.
