Blood pressure in free-ranging gray wolves (Canis lupus) immobilized with tiletamine and zolazepam
This study aims to evaluate blood pressure measurements in immobilized free-ranging gray wolves (Canis lupus) in Sweden. Eight immobilized wolves (five adults and three juveniles) were included in this study. All wolves were darted from a helicopter with darts containing 250 milligrams of tiletamine...

Eight immobilized wolves (five adults and three juveniles) were included in this study. All wolves were darted from a helicopter with darts containing 250 milligrams of tiletamine and 250 milligrams of zolazepam.
