Surprisingly decent entry in the killer animal genre. The premise is actually kind of believable, unlike most of these movies.

McCallum and Wyner are good in this thing, but it feels like a 70's made for TV. It isn't gory enough to touch that vibe and most of the attacks look like happy pet owners getting on the ground and wrestling with their dogs playfully. A huge plot hole (the how...which we kind of know from early on but is never confirmed) is left there making the whole thing unsatisfying.
