Learn how to measure your dog for the Hurtta Training Jacket ECO, with chest, neck, and back length rules, plus fit trade-offs for active dogs.
Quick Answer
For the Hurtta Training Jacket ECO, measure your dog's chest girth, neck girth, and back length, then choose the size based on the largest of those three measurements to ensure full coverage without restricting movement.
Why the Largest Measurement Wins
The Training Jacket ECO is designed for active winter training, so it needs to move with your dog. If you size by chest only, a longer back or thicker neck could leave gaps. Using the largest measurement as your guide ensures the jacket covers everything it should.
A snug but not tight fit is the goal. You should be able to slide two fingers flat between the jacket and your dog's body, but the jacket shouldn't sag or twist during movement.
Trade-Offs: Sleeves and Mobility
Unlike a vest, the Training Jacket ECO includes sleeves, which add coverage but can restrict movement if too tight. Measure the chest at its widest point to allow full shoulder rotation. If your dog has a deep chest or broad shoulders, you may need to size up for comfort.
The jacket's breathable, waterproof fabric is thin, so it layers well, but don't size up just for layering unless your dog is between sizes. A too-large jacket can bunch and chafe during activity.
Decision Rules for Sizing
- Measure Chest Girth: Wrap a tape measure around the widest part of the ribcage, just behind the front legs. Keep it snug but not tight. Record the number in inches or centimeters. This is the most critical measurement for the Training Jacket ECO.
- Measure Neck Girth: Measure around the base of the neck where the collar sits. Add two fingers' width for comfort, especially if your dog wears a harness while training. If between sizes, choose the larger size if the neck measurement is close to the upper limit.
- Measure Back Length: Measure from the base of the neck (where the collar sits) to the base of the tail. This ensures the jacket covers the back without riding up. If the back length is between sizes, size up to avoid a short jacket.
- Choose the Largest Size: Compare all three measurements to the size chart. Select the size that accommodates the largest measurement. If one measurement is significantly larger, consider a different style or a custom fit. Never size down to make the jacket tighter; it should never restrict movement.
Product Facts
- Training Jacket ECO: The Training Jacket ECO is made with a soft, breathable, thin-yet-durable, waterproof fabric and includes sleeves for added coverage. Because the fabric is thin and breathable, you can fit it closer to the body than a bulky winter coat, but the sleeves mean you must measure the chest carefully to avoid restricting shoulder movement.
