Four legged jacket

I needed to knit a jacket for my King Charles Cavalier, Hollie. She needs clipping, but the weather has turned so cold. It needs to have 4 legs as she has alopecia on her back leg, so is almost bald. Here goes:

Cheap aran yarn. Knit flat on 5mm circular needle.

Cast on 80 stitches.
Work back and forth, K1 P1 rib 6 rows, making a button hole at the beginning of the 3rd row as follows: K1 P1 K1 yo K2tog P1

Row 7. Rib 6. K20. Rib 28.K20 Rib 6
work 7 more rows as stitches present, making a button hole at the beginning of row 13.

(14 rows in total to this point)

Divide for front legs: Work 26 sts as set and turn. Continue working on these 26 sts for 14 more rows, working a buttonhole at the beginning of the last row. Break yarn.

Rejoin yarn to the centre 28 sts and work in K1 P1 rib for 15 rows. Break yarn

Rejoin yarn to last 26 sts and work as stitches present for 15 rows.

Next row - work across all 80 sts as set, so joining all sections together again.

Work 20 rows as set, making a button hole on 13th row.

Next row: Work 26 sts. Cast off 28 sts (all the centre rib section). Work 26 sts.

continue on the last 26 sts for left back:

1) Rib 6 P12 P2tog rib 6
2) Rib 6 K2 tog K11 rib 6
3) rib 6 P10 P2tog rib 6
4) rib 6 K2 tog K9 rib 6
5) rib 6 P8 P2tog rib6
6) rib 6 K2tog K7 rib 6 = 20sts on needle

7) rib 6 P14
8) K14 rib 6
Rep last 2 rows 10 more times

Work 6 rows K1 P1 rib
Cast off.

Rejoin yarn to remaining sts for right back.
1) Rib 6 P2tog P12 rib 6
2) Rib 6 K11 K2 tog rib 6
3) rib 6 P2tog P10 rib 6
4) rib 6 K9 K2 tog rib 6
5) rib 6 P2tog P8 rib6
6) rib 6 K7 K2tog rib 6 = 20sts on needle

7) P14 rib 6
8) rib 6 K14
Rep last 2 rows 10 more times

Work 6 rows K1 P1 rib, working a button hole at the end of row 3
Cast off

 Work will now look like this:







Pick up and knit 10 sts for left back leg, along stocking stitch section of left back. Marked with pins in the next picture:

work 12 rows K1 P1 rib, increasing 1 stitch at each end of every odd numbered row. (20 sts)
13) cast on 5 sts. rib to end
14) cast on 5 sts. rib to end (30sts)
work 10 more rows in rib
Cast off

Repeat for right back leg.

Front legs: Pick up and knit 24sts around leg opening.
K1 P1 rib 8 rows.

Should be looking like this:

Cast off. Sew leg seams and weave in ends

Sew buttons to correspond with buttonholes.

Put on very shy dog. (wash floor before taking pics!)

This is my first ever written pattern (and blog!) so any feedback would be much appreciated. Also, I would love to see any mods made to this pattern!
