Blue Heartstrings Cord Jumper, Harness & Lead Bundle: Sizing Guide

The bundle's real decision: two sizes, not one

The Blue Heartstrings Cord Jumper, Harness & Lead Bundle pairs a cable-knit jumper with a matching adjustable neck harness and lead in soft baby blue cord. It is sold as a coordinated set, but the jumper and harness are sized independently. That means the most useful buying question is not simply "what size is my dog?" but "which jumper size and which harness size fit my dog?" The supplied size charts give you the numbers to answer both.

This guide works through those measurements, shows where the jumper and harness ranges overlap, and explains what the set does and does not tell you. It is written for shoppers deciding whether this particular bundle is the right purchase, not for fitting a harness you already own.

Harness measurements to compare against your dog

• Blue Heartstrings Cord Jumper, Harness & Lead Bundle: Harness sizes and ranges: XXS neck 22–25 cm, chest 30–40 cm; XS neck 29–36 cm, chest 35–48 cm; S neck 35–43 cm, chest 41–54 cm; M neck 39–50 cm, chest 46–60 cm; L neck 42–55 cm, chest 57–80 cm. The harness is the piece that carries the lead, so its neck and chest ranges are the first filter. Measure both, then choose the smallest size whose ranges contain both measurements.

  

• Blue Heartstrings Cord Jumper, Harness & Lead Bundle: The harness has a fully adjustable neck and chest strap, a white D-ring for lead attachment, and slips over the head before fastening at the side. Adjustability gives some room within a size, but it does not replace measuring. The D-ring position and side fastening also tell you how the harness goes on and where the lead connects.

Jumper measurements to compare against your dog

• Blue Heartstrings Cord Jumper, Harness & Lead Bundle: Jumper sizes and ranges: XXS neck 20 cm, chest 32 cm, back 27.5 cm; XS neck 24 cm, chest 36 cm, back 30 cm; S neck 30 cm, chest 44 cm, back 38 cm; M neck 32 cm, chest 54 cm, back 45 cm; L neck 36 cm, chest 56 cm, back 53 cm. The jumper uses single neck, chest and back figures rather than ranges. Compare your dog's measurements to these figures directly; the back length matters most for coverage along the spine.
• Blue Heartstrings Cord Jumper, Harness & Lead Bundle: The jumper is a soft, stretchy cable-knit with embroidered heart details, made from 45% acrylic, 26% nylon and 29% polyester, and is machine washable. Stretch helps the jumper accommodate small differences, but it is not a substitute for the size chart. Machine washability is relevant to daily wear and care.

How to match jumper and harness sizes

The bundle is offered in combinations of harness size and jumper size, so you are not locked into the same letter for both pieces. Start with the harness, because it is the safety-critical item: measure neck and chest, then find the harness size whose ranges contain both. Next, measure your dog's back length and chest for the jumper, and choose the jumper size that best matches those figures. If your dog sits between jumper sizes, the stretchy knit gives some tolerance, but the supplied chart is still the reference point.

Because the harness ranges overlap between adjacent sizes, more than one harness size may appear to fit. In that case, use the chest measurement as the deciding figure, since the chest strap carries most of the load. The neck strap can be adjusted, but the chest range is the harder limit.

What the bundle includes and what it does not confirm

The supplied information covers the jumper, harness and lead. It does not include feeding, treatment or medical advice, and it does not specify cleaning instructions for the harness and lead beyond general care notes. Treat the absence of detail as a reason to check the product page or contact the store before purchase if those points matter to you.

• Included: Cable-knit jumper, adjustable neck harness with white D-ring, and a 152 cm × 2 cm lead in baby blue cord with white embroidered hearts.
• Not confirmed by supplied information: Specific washing instructions for the harness and lead, and any breed or weight guidance. Use the measurements rather than breed labels.
• Care note that is supplied: Dog accessories are subject to normal wear and tear, and you should check regularly that all items remain safe for your dog to wear.

When the coordinated set makes sense

The Blue Heartstrings bundle is a practical choice if you want a matching jumper, harness and lead without assembling them separately. The pieces can be worn together or styled separately, so the set works for cool-weather walks and indoor downtime alike. The lead is 152 cm long and 2 cm wide, which is a standard walking length; the harness has a white D-ring for attachment.

The main trade-off is that you are committing to two size decisions at once. If your dog is between sizes in either piece, or if you already own a harness you trust, buying the jumper alone may be simpler. The bundle's value comes from the coordination and the combined price, not from features that change how the harness or jumper performs.
