It happened in Highland Park Sunday. Police say the man was swinging the French bulldog on a leash "like a yo-yo."
Los Angeles Animal Services says the dog was treated for cuts and scrapes and is lethargic, but should make a full recovery.
The 28-year-old owner, identified as Joseph Fragoso, faces felony charges and could get three years in jail if convicted.
The puppy is being cared for at the North Central Animal Shelter at 3201 Lacy Street. According to Annette Ramirez of Los Angeles Animal Services, the puppy will be held at the shelter for 30 days as evidence. Then depending on a court decision, he may be up for adoption to the public.
