A New York animal shelter is seeking donations of Viagra to treat a pit bull with a heart condition.

Staff members at the Little Shelter Animal Rescue and Adoption Center in Huntington, on Long Island, say 6-year-old Ingrid needs two of the little blue pills every day or she will risk heart failure. They say a vet suggested it.

The pills cost about $10 apiece, and the shelter has been asking Viagra users to pitch in and donate their unused pills.

Viagra was originally developed as a heart medication but is now used mainly by men to give their sex lives a boost.

A pit bull named Chaco was euthanized Tuesday night after animal care workers say he attacked his owner earlier in the day as she was trying to stop him from going after a cat.

Julie St. Gregory, a spokeswoman for the San Jose Animal Care Center, said today that the owner “surrendered” her pit bull to be put down, adding that the unlicensed dog had no previous record of violence with the agency.

San Jose police officers found the pit bull about 10 p.m. in the 500 block of Madera Avenue. The dog bit his owner all over her arms and legs, according to a report.

Family members were able to restrain Chaco until animal care services arrived to take him away, the police report states. The woman was treated for her injuries, which police say were not life-threatening.
