You are advancing nicely, for the time being! Obviously, you've already learnt a lot about aperture - while taking these photos of your dog, you've changed the aperture value from 22 to 4, so you did a good demonstration of the impact of the aperture's value (and the distance between you and the subject) on the depth of field (area which is in-focus vs area(s) out of focus).
But these are far from being good photos (with the exception of "the eye"). What can be changed to make it better?
-get slightly closer (or just zoom-in little more), as to completely remove that brown pillow in the background and the part of the foreground (nothing should be visible in front of the dog's tongue).
-same goes for the rose in that close-up and the first pic
-"the vase" is the worst photo in this set - too many objects laying around are distracting viewer's attention - remove that box, get closer to the vase and try to blur the background
-"the eye" is a quite acceptable photo (although it could be argued whether the brow should be slightly less blurred or not, to maintain the uniformity of distribution of details throughout the photo, since the area below the brow and below the eye is very sharp and rich with details).

A rather severe cropping could produce different results (try to think in that direction):
the eye, slightly cropped and sharpened:
I'll keep this updated as much as I can.
