I came across an article on the internet whilst doing research, I just had to share some of it with other like-minded Pet Owners.
~~ “Animal shelters are stressful environments for dogs, and so anything that helps them to be less stressed is beneficial.” ~~
Scent Enrichment apparently works well for Dogs in shelters, it has showed a Reduction in their Vocalisations and Increased Species-Specific Behaviour and Slept Better. The article mentioned using Cotton Cloths scented with Ginger, Coconut, Vanilla or Valerian which are then placed in the environments surrounding the Dogs, when the scented cloths were present, Dogs Vocalized Less, and since Barking, Whining etc. can be signs of Stress, this suggests they were Calmer and it was found and confirmed that the response after being exposed to such scents always gave Positive Enrichment and Mental Health Benefits to the animal.
