Bernat crochet pet bed
This pattern can be found here:
Notes: Finished size; 27" diameter
M was too small but L too big so I worked as the pattern to 9th round and measured at this point; then continued as set to measurement required.
I added the cave top by working the top circle in reverse...working 2Tr together over 2 stitches instead of 2Tr in one stitch and allowing a gap on the previous rows.
