Only 13weeks and our first but just assumed all normal.
I think the circles in the park/garden is her just not wanting to go too far away from us, but wanting to run so she circles instead.
Our pup is very cuddly and loves to lick our hands, arms etc. I draw the line at her trying to lick my chest though!
With the pooing she seems to be trying to aim for a particular spot that she has sniffed out as ideal. I don't get it myself but seems to be fairly consistent.
being a pup our seems to be almost constantly excited! She tends to roll on her back a lot though rather than spin around. In the mornings or if we have had to leave her at home for a bit, we we got to greet her she does a weird grovel crossed with a commando crawl. Almost like wriggling along the floor like an over excited snake .
