It is well established that maternal factors can affect the abilities of offspring to cope with stressors and influence their overall welfare states. However, effects have not been extensively explored in US commercial breeding kennels (CBKs). Therefore, objective this study was identify if fear stress dams affected puppy metrics CBKs. Bitches (n = 90) were tested at 6 weeks prepartum (6 W Pre), again puppies 390) 4 (4 Post) 8 (8 postpartum. Dams underwent stranger approach isolation tests,...
Poor dam welfare throughout the peri-parturient period can also negatively affect that of their offspring. This study aimed to identify changes in physical, physiological, and behavioral metrics indicative period. Dams (n = 74) from eight U.S. Midwest commercial breeding (CB) kennels were tested at 6 1 week prepartum, 4 8 weeks postpartum. At each time point dams underwent a stranger approach test, physical health assessment, hair collection for cortisol concentration (HCC) fecal...
Many puppies from commercial breeding kennels (CBKs) are transported by ground their of origin to a distributor. This experience may elicit fear and stress during sensitive developmental period, which in turn negatively impact the puppies’ short- long-term welfare. study aimed measure short-term effects transportation on puppy welfare metrics. Eight-week-old (n = 383) 12 CBKs were tested at (pre-trans) ~48 h after arriving distributor (post-trans). At each location, underwent an isolation...
Background: Canine behavior plays an important role in the success of human-dog relationship and dog's overall welfare, making selection for a vital part any breeding program. While behaviors are complex traits determined by gene × environment interactions, genetic desirable behavioral phenotypes remains possible. Methods: No genomic association studies dog to date have been reported on commercial (CB) cohort, therefore, we utilized dogs from these facilities (n = 615 dogs)....

Throughout their lives, dogs may experience various stressful events. Early neurological stimulation (ENS), which was shown to alter stress responses beneficially in some animals, has not been fully explored dogs. Seventy-six small-breed puppies from one commercial breeding kennel were divided into three treatment groups: ENS, held, and control. Puppies the ENS group received 30 s of handling exercises for 21 days after birth; held simply same amount time. control managed as per normal...
