Help needed with Crochet Pattern

Hallo,

I bought a crochet pattern for a dog which is not very detailed. I want to crochet the paws and I do not really understand what I need to do.

My last round:

Rnd: 14: *11 single crochet, 1 decrease* x 2
and now the part I do not understand:

Crochet 5 extra single crochet stitches and start crocheting the heel back and forth
Row 1: 4 single crochet,1 slipstitch
Row 2: 5 single crochet, 1 slipstitch
....
Q1: What does it mean: "Crochet 5 extra crochet stitches"?
Q2: How do I increase the stitches from Row 1 to 2 without increasing?

Many thanks in advance for your help!
