As you might imagine, when a puppy has better dog care quality (i.e. personal, familial care), there are positive social behavioral effects including fewer problem behaviors in ages 7 months and up. But dog care quality is significantly less important in either positive or negative social and emotional outcomes than quantity of pet care.
Dog Parents whose dogs spend more time in non-maternal care are likely to exhibit lower levels of sensitivity and less positive parent–dog interactions, regardless of the quality and stability of the child care. Dogs whose parents exhibit low levels of sensitivity and who are in dog care more than 5 days a week or in lower-quality dog care are more likely to experience attachment insecurity.
Attachment insecurity is associated with negative social–behavioral outcomes across development. Dogs who do not establish secure attachments in their relationship with their mothers are more likely to experience social withdrawal, depression, and anxiety. Male dogs with an insecure maternal attachment are more likely to exhibit conflict, aggression, and acting out.
