Sixty-seven dogs that showed signs of distress when separated from their owners (destructiveness, excessive vocalisation and house soiling) and hyperattachment were used in a randomised, blind trial to assess the potential value of a dog-appeasing pheromone in reducing the unacceptable behaviours. For ethical reasons, there was no placebo group and the effects of the pheromone were compared with the effects of clomipramine which is regularly used to treat this type of problem. The undesirable behaviours decreased in both groups, but the overall assessment by the owners indicated that there was no significant difference between the two treatments, although there were fewer undesirable events in the dogs treated with the pheromone, and the administration of the pheromone appeared to be more convenient.

This study was designed to determine the potential value of dog-appeasing pheromone (dap) in reducing stress in puppies newly adopted from a pet shop. The trial was triple-blinded and placebo-controlled. After their arrival at the pet shop, 32 puppies were fitted with a dap collar and 34 were fitted with a control collar, according to a randomisation protocol. Adopting owners were contacted by telephone, three and 15 days after they had adopted a puppy, to obtain information about the puppy's integration into the family, and particularly about any signs of distress shown by the puppy when it was socially isolated. All the isolated puppies from the control group vocalised during the first night. Signs of distress, particularly vocalisation, were significantly lower in the dap group on day 3 and throughout the rest of the study, and vocalisation during the night ceased significantly sooner in this group. These differences were observed in puppies of small, medium and large breeds. The dap collars had no effect on the incidence of house soiling.

This study was designed to determine the potential value of dog-appeasing pheromone (DAP) in reducing behaviours associated with fear of unfamiliar people and new surroundings in puppies newly adopted from a pet shop. The study was triple-blinded, randomised and placebo-controlled. It used 66 puppies (32 fitted with a DAP collar and 34 control) and the adoptive owners were contacted by phone three days and 15 days after they had adopted the puppy to question them about its reactions to specific situations eliciting fear. Fifteen days after the treatments significantly fewer of the puppies with the DAP collars showed signs of fear when facing unfamiliar people at home and/or during outings. This difference was irrespective of breed size.
