Study shows dog jealously trait

I still remember the time my dog saw me walking our neighbor’s dog while they were on vacation. It sounds crazy, but I could have sworn I saw a hint of jealousy in his eyes when I returned.

According to the results of a recent Vienna-based study, my inclination about dog jealousy could be right.

In the study, pairs of dogs were given a reward after they gave their paw (like a handshake). Later on one of the dogs was asked to shake hands but was not give a treat, while the other dog continued to do tricks for treats. According to the BBC article, “The dog without the reward quickly stopped doing the task, and showed signs of annoyance or stress when its partner was rewarded.” They also did the study without the partner and the dog did the task much longer without a treat, which proves it wasn’t just food-based frustration.

Scientists say this type of sensitivity was previously only found in primates.
