Ruffwear Singletrak Hydration Pack with Built-In Dog Harness

The Ruffwear Singletrak Pack is widely considered the "Goldilocks" of dog hydration packs. It hits that sweet spot for owners who need more than a standard harness but don't want the bulk of a full multi-day trekking pack.

It’s essentially a low-profile hydration vest designed for high-energy days on the trail.

Core Features & Benefits

Why It’s a Fan Favorite

• The "Anti-Chafe" Build: Because it’s sleek, it doesn’t interfere with a dog's shoulder movement. It’s perfect for trail running or mountain biking where speed and agility are key.

• Weight Distribution: The bladders sit close to the dog's center of gravity. Just remember the golden rule: A dog should generally not carry more than 10-25% of their body weight.

• Versatility: Even without the water, the small side pockets are great for pick-up bags, a collapsible bowl, or a small first-aid kit.

   

Things to Consider

• Minimal Storage: If you’re looking to pack a weekend’s worth of kibble and gear, this isn't it. This is a "day trip" pack.

• Cooling: While it doesn't have the "swamp cooler" tech built-in, the ice-cold water in the bladders against the dog's ribs can provide a slight cooling effect on hot days.

Pro-Tip for Fit

When fitting your dog, ensure you can fit two fingers comfortably under all straps. If the pack is sliding to one side, it’s usually because the water levels in the two bladders are uneven—try to keep them balanced as your dog drinks!

Ruffwear Singletrak Size Chart

Ruffwear uses a standard sizing scale across most of its harness-based packs. If your dog is between sizes, Ruffwear generally recommends sizing down for a more secure, "flop-free" fit, unless your dog is still a growing puppy.

How to Measure Correctly

1. Find the Widest Part: Use a soft tailor’s tape (or a piece of string you can measure against a ruler later).

2. The "Two-Finger" Rule: When the pack is on, you should be able to fit two fingers snugly between the straps and your dog’s fur.

3. Check for Elbow Clearance: Ensure the front chest strap doesn't sit so close to the armpits that it rubs when the dog runs. There should be a "hand's width" of space between the front legs and the girth strap for most medium-to-large dogs.

Quick Fit Check

• Balance the Load: The Singletrak is designed to sit close to the body. If the pack is sliding to one side, check that your water bladders have roughly equal amounts of water.

• Adjust Five Points: This pack has five points of adjustment (two on the neck, three on the belly/chest). Take the time to dial these in while the dog is standing naturally.
