The Alpine Ascent Dog Sweater is designed for the modern, active dog who doesn't let a little chill stop their adventures.

The high mock neck adds extra coziness, making this the perfect project for knitters ready to elevate their skills with a rewarding, wearable result.

Materials Needed

Before you begin, gather the following supplies to ensure a smooth knitting experience. This pattern is written for a worsted/aran weight yarn, which provides excellent stitch definition for the cables.

  • Yarn: Approximately 600-800 yards of worsted/aran weight wool or wool-blend yarn (e.g., Cascade 220 Superwash). The sample shown uses 'Stormy Sky' (deep charcoal grey) and 'Frosted Pine' (muted sage green) for a contrasting, alpine-inspired look.
  • Needles:
    • US 7 (4.5mm) circular needles (24-32 inch cables) for ribbing.
    • US 8 (5.0mm) circular needles (24-32 inch cables) for the main body.
    • US 8 (5.0mm) double-pointed needles (DPNs) for working the sleeves in the round.
  • Notions: Stitch markers (at least 4), cable needle, tapestry needle for weaving in ends, scissors.
  • Gauge: 18 stitches and 24 rows = 4 inches in Stockinette stitch on larger needles, after blocking. Always check your gauge to ensure the correct fit.

Body (Worked in the Round)

Step 1: Cast On & Ribbing
With smaller needles (US 7), CO 84 (96, 108, 120) sts. Join to work in the round, being very careful not to twist your stitches. Place a marker to indicate the beginning of the round. Work in k2, p2 ribbing for 3 inches.

Step 2: Set Up Pattern
Switch to larger needles (US 8). Set up the cable pattern as follows:

Round 1: *Knit 12 (15, 18, 21) sts, pm, work Cable Panel (see below) over next 12 sts, pm, knit 12 (15, 18, 21) sts, pm, knit 12 (15, 18, 21) sts, pm, work Cable Panel over next 12 sts, pm, knit 12 (15, 18, 21) sts.* Repeat from * to * once more. You will have 4 cable panels total, with stockinette stitch sections between them.

Cable Panel (over 12 sts): Work these 8 rows repeatedly.

  • Row 1 (RS): P2, C4F, C4B, p2.
  • Row 2 (WS): K2, p8, k2.
  • Row 3: P2, k8, p2.
  • Row 4: K2, p8, k2.
  • Row 5: P2, C4B, C4F, p2.
  • Row 6: K2, p8, k2.
  • Row 7: P2, k8, p2.
  • Row 8: K2, p8, k2.

Continue working in pattern until the piece measures 14 (15, 16, 17) inches from the cast-on edge, ending after a WS row (Row 2, 4, 6, or 8 of the cable pattern).

Divide for Armholes

Step 3: Bind Off for Armholes
On the next round, work in pattern to 6 (7, 8, 9) sts before the first marker. BO 12 (14, 16, 18) sts for the first armhole, removing markers as you go. Work in pattern to 6 (7, 8, 9) sts before the next marker. BO 12 (14, 16, 18) sts for the second armhole. You will now have two separate sections: Front (42 (48, 54, 60) sts) and Back (42 (48, 54, 60) sts).

Chest (Front) - Worked Flat

Step 4: Shape the Chest
Work flat on the front stitches only. Continue in pattern (maintaining the cable panels as established) while decreasing 1 stitch at each edge on every RS row 4 (5, 6, 7) times. To decrease: On RS rows, k1, ssk, work in pattern to last 3 sts, k2tog, k1. On WS rows, purl all stitches (maintaining cable pattern as written).

Step 5: Work Even
After completing the decreases, work even in pattern until the armhole measures 6 (7, 8, 9) inches from the underarm. BO all stitches loosely.

Back - Worked Flat

Step 6: Shape the Back
Work flat on the back stitches. Continue in pattern (maintaining the cable panels) while decreasing 1 stitch at each edge on every RS row 4 (5, 6, 7) times, using the same decrease method as for the front.

Step 7: Work Even
After completing the decreases, work even in pattern until the armhole measures 6 (7, 8, 9) inches from the underarm. BO all stitches loosely.

Sleeves (Worked in the Round)

Step 8: Pick Up Stitches
With larger DPNs (US 8), pick up and knit 36 (40, 44, 48) sts evenly around the armhole. Place a marker and join to work in the round.

Step 9: Shape the Sleeve
Work in Stockinette stitch (knit every round) for 1 inch. Then, work a decrease round: k2tog, knit to last 2 sts, ssk. Repeat this decrease round every 6 rounds until 24 (28, 32, 36) sts remain.

Step 10: Sleeve Cuff
Continue even in Stockinette stitch until the sleeve measures 8 (9, 10, 11) inches from the underarm. Switch to smaller DPNs (US 7) and work in k2, p2 ribbing for 2 inches. BO loosely.

Neck (Worked in the Round)

Step 11: Pick Up for Neck
With the smaller circular needle (US 7), pick up and knit 60 (68, 76, 84) sts evenly around the neck opening. Join to work in the round.

Step 12: Knit the Mock Neck
Work in k2, p2 ribbing for 4 inches. BO loosely to ensure the neck can stretch comfortably over your dog's head.

Finishing

Step 13: Weave in Ends
Using a tapestry needle, weave in all yarn ends securely on the wrong side of the sweater.

Step 14: Blocking
Block the sweater to the specified measurements. Pay special attention to the cable panels, gently pinning them open to enhance their definition and create a professional, polished look. Allow to dry completely before dressing your dog.

Your Alpine Ascent Dog Sweater is now complete! Enjoy the satisfaction of seeing your furry friend stay warm and stylish in a garment you made with your own hands.
