Dog is quite embarrassed…

Cast on 48 with smaller needles and CC, 2x2 for 18 rounds.
Switch to MC and larger needles and knit, Inc 2 sts every other round to 76 sts.
Bind off 6 sts for each leg opening, with 14 between legs.
Cast on the leg sts again next round, and knit 27-28 rounds before belly sts.
Work 20 rows with decreases for back.
Legs too narrow…next time bind off 8 for each leg.

Neck circ. 10”
Chest circ. 15.5”
Back length 14”
Neck to leg 6”
Between armpits 3”

With math:
Neck 10 x 4.5 = 45 (46 for 1x1, or 48 for 2x2)
Neck to leg 6
Chest 16+1 x 4.5 = 76.5 (76)
Between legs 3 x 4.5 = 13.5 (14)
Around leg 4.5 x 4.5 = 20.5 (I think I did 16 only, what was I thinking???)
Neck to tail 14
