Best Waterproof Service Dog Gear: Biothane Collars, Leashes, and Harnesses That Work
Service dogs work hard. Their gear needs to perform every day, in public and at home, without causing distractions, discomfort, or breakdowns.
At Outer Space Dog Gear, we make handcrafted biothane equipment designed for real working teams. Our gear is waterproof, stinkproof, easy to clean, and built to meet the physical and professional demands of service dog work.
Whether your dog assists with mobility, PTSD, autism, or other disabilities, this guide will help you find gear that supports your team and fits your lifestyle.

Service dog teams rely on gear that is reliable, clean, and comfortable. Good equipment should:
✅ Stay dry and odor-free in all environments
✅ Be easy to wipe clean between uses
✅ Offer a secure, comfortable fit
✅ Support mobility, guiding, or alert tasks
✅ Allow for custom identification or warnings
✅ Fit the team’s needs without getting in the way
Some handlers want gear that blends in. Others want bold, visible colors and text. We offer both, because every team is different.
Why We Use Biothane
Biothane is a coated webbing material that’s ideal for service dog gear. It doesn’t absorb water, doesn’t fray, and stays clean with minimal effort.
- Waterproof and stinkproof
- Smooth surface that wipes clean in seconds
- Strong enough for daily use, flexible enough for comfort
- Comes in a wide range of professional and high-visibility colors
Our customers choose biothane for its durability and low maintenance. Many have used the same gear for years without needing a replacement.
