In this movie werewolves apparently die when they are shot. However, silver bullets are needed in the previous Howling movies. This could be because in this film they are technically were-thylacines rather than werewolves.
When the man is thrown from the hospital building, the following scene shows his body coming from the roof, but the room is not on the roof.
When the two doctors are asking Thylo about the thylacine, the picture in the lower corner of the display is hunters holding a dead thylacine in the close shots, but a yawning Tasmanian devil in long shots.
Jerboa goes from wearing shoes to being barefoot to having shoes and back to being barefoot throughout the movie.
A partially-transformed werewolf woman gives birth. During the birth scene and in a later scene, closeups of her belly reveal the netting underneath the actresses' artificial fur. This might not have been visible to many on videocassette, however.
After the power failure at the hospital, the edges of the contact lenses Dagmar was wearing are visible. (This was likely not visible to viewers of the videocassette)
A female werewolf becomes pregnant. Her peers are shown to have keen sense of smell earlier in the plot, to the point of aiding them in tracking her down in the city. Despite this, when she returns to them, they do not notice from her scent that she is pregnant.
