TAMPA, Fla. -- The Humane Society of Tampa Bay is getting 21 dogs from Puerto Rico as part of a campaign by the national agency to relieve overcrowding in the island's shelters.

The society estimates that there are nearly 300,000 street dogs or strays in Puerto Rico.

The dogs are considered vermin there, according to the society, and are abused and used in ritualistic ceremonies.

The dogs are sociable with the staff of the Humane Society.
