2. Dogs can be pessimistic
If you think all dogs are happy-go-lucky and brimming over with energy, think again! New research has shown that dogs can be optimistic or pessimistic. Those that are optimistic expect rewards, will get up and try again if things don’t go their way, and take risks. Those that are pessimistic are averse to taking risks and tend to give up when they have setbacks; they almost sound human!
