Dogs from severe hoarding have to be rehabilitated before they can be re-homed with a family. According to a 2016The BARk article by Dr. Karen London :
I'm hoping we'll be able to nurse the sweetie back to health and happiness, teach them about walkies and leash, heel, sit and come, general house behavior and peewees rules, and find a good understanding furever family...This time a foster failure is not on the cards, I'm a setter Mama pure and simple, but I'm willing to lend a hand in times of need.Dogs from hoarding situations were more fearful and more sensitive to touch than the control dogs. They showed more behavior associated with attachment, attention-seeking and separation anxiety. They exhibited a greater frequency of urination and defecation when left alone, destructive chewing, submissive urination and repetitive behaviors.Dogs rescued from hoarding situations were less trainable and less aggressive. They were less likely than the control dogs to be overly excitable or energetic. They had a lower probability of being persistent barkers, of chasing small animals, or of exhibiting rivalry for resources with other dogs.
