Dogs often walk in circles before settling down for a snooze. This curious behavior is actually hardwired in them from prehistoric timesFido's wild dog ancestors would walk in circles to make a nest — an area with stomped-down grass or underbrush where they could sleep. This behavior may have also driven out snakes or large insects that otherwise might have bothered them, Irvine said. Moreover, a nest would mark the dog's territory, telling other dogs to stay away, she said

   Zooming around in circles in hot pursuit of a furry thing that seems just a hair out of reach … Yes, tail chasing can be a pastime for some dogs. So, why do they do it?

Of course, that's not the only reason for running round and round — your dog could be chasing an itch if he or she has fleas or ticks, according to the journal.If the tail-chasing behavior becomes excessive, it could be a sign of the doggy version of OCD, called canine compulsive disorder.

   Some dogs are just the cutest snuggle bunnies but there are those will get really turned off or aggressive if hugged. Dogs do not have arms for hugging.  Humans or Primates love to hug but dogs atypically do not because hugging in dogs terms can be dominance.   So, the next time you are hugging your dog watch to see if they squirm, tense up or turn their head (they are actually avoiding eye contact) and chances are they do not like being hugged but you do.
