There's no doubt that dogs are insightful and sensitive beings,with the ability to sense emotions and read humans' facial expressions. The American Kennel Club (AKC) says dogs combine hearing and sight(correspond) happy and angry faces with happy and angry sounds. Researchers have found that dogs can distinguish the positive sound of laughing the negative sound of crying. The dogs were found to be more upset and stimulated by the negative sounds than positive ones. 2018 study published in Scientific Report, a peer-reviewed online journal published by Nature Research, (show) that dogs use the right side of their brain for processing negative emotions and the left side for positive ones.
Speaking to Newsweek, AKC's officer. Dr. Jerry Klein, explained dogs can certainly become (depress) and anxious. There have been reports of dogs (experience) depression and loneliness following the (lose) of an owner or a "fellow member" of their pack, as well as a change from (they) normal routine. "But whether dogs get 'sad' is less certain," Klein told Newsweek. Klein said from a (strict) scientific standpoint, there isn't strong evidence that dogs feel people would classify as sadness. "Dogs live more in the moment and don't have the ‘self-consciousness' to inwardly think like people do."
