Facts & Research

Some research notes to consider:dog in shelter

  • In a study looking at the noise levels in animal shelters they reported that noise can reach over 100db where levels over 70db are considered loud. (Coppola et al, 2006)
  • Noise is a physical stressor that can lead to behavioral, physiological, and anatomical responses, including intestinal problems, and immunosuppression. (Spreng, 2000)
  • The presence of these food enrichment toys stimulates appetitive behaviors and increases the level of activity (exercise). It also appears to result in lower barking frequencies (lower noise). Thereby promoting the welfare of dogs housed in kennels. (Lidewij L. et al, 2008)
  • One study showed that moving the bed to the front of the cage as well as adding toys can increase the chance of that dog being adopted. (Wells and Hepper, 2000)
  • The addition of a toy made the kennel environment more appealing to visitors even when the dog displayed no interest in the toy, thus improving adoption chances. (Wells et al, 2002a)
