Information-seeking behaviour of sniffer dogs during match-to-sample training in the scent lineup

Impact of individual training parameters and manner of taking breath odor samples on the reliability of canines as cancer screeners

“…After successfully completing 3 training phases, dogs were considered ready for the working phase. This training method and qualification system proved to be efficient in our previous studies (Jezierski et al, 2008(Jezierski et al, , 2010.…”

“…A wide variety of dog breeds and of individuals of very different ages and skills, and of previous training, have been used for the cancer detection. According to our previous experience (Jezierski et al, 2008(Jezierski et al, , 2010, selection criteria for dogs that will be most suitable and successful in lineup training have not been verified as useful.…”

“…The dogs were divided into 2 age-groups: 3 older dogs aged between 20 and 22 months (COU, CYG, GRO) and 3 younger dogs (identified by the first letters of their names, BIS, OSK, TYT) that were 6 months old at the beginning of the training. The younger dogs were littermates coming from parents that had previously achieved very good results in human scent lineups (Jezierski et al, 2008(Jezierski et al, , 2010. There was no preliminary selection of the older dogs for the training, either on the basis of their sniffing performance or on demonstrated play or retrieval drive.…”

Scent Identification in Criminal Investigations and Prosecutions: New Protocol Designs Improve Forensic Reliability

How to train a dog to detect cows in heat—Training and success

“…During imprinting phase, dogs learn to associate a specific scent with reinforcement. In the actual discrimination training dogs are trained to identify this odour, to differentiate it from distracting odours (Fischer-Tenhagen et al, 2011), and to indicate the target odour by performing a trained indication behavior, often lying down or sitting at the target (Jezierski et al, 2008). Optimizing rewarding time and place has great influence on the training progress (Mackintosh, 1983).…”
