This one feels like a bit of a rehash to me, but let's see what you think. Here's the blurb for Breed from Coming Soon:

The Breed follows five young friends who vacation on a peaceful deserted island only to discover that the canines they befriend are genetically altered and possess a frighteningly high level of intelligence -- with an appetite to match.

Okay, follow me on this one, I'll try to keep it short.

Deep Blue Sea - Sharks + Dogs - Man Made Structure + Island = ?

Tough sum to work out, but see if you can. They also provide the cast list for this Wes Craven Production:

Michelle Rodriguez, Taryn Manning, Oliver Hudson, Hill Harper and Eric Lively will star in the independent horror film The Breed. First Look Media and DEJ Productions have acquired worldwide rights, says The Hollywood Reporter... ...Lost star Ian Somerhalder had been announced to star in the film but since has dropped out.

Wise move methinks.
