"Free shipping made the decision easy, and the quality did not disappoint at all. I had a small issue with sizing but their customer service was excellent, no hassle getting it sorted out. Genuinely one of the smoothest shopping experiences I've had, will definitely be ordering again!"

TrailGuard K9 Tactical Dog Backpack Harness

Built for active dogs and outdoor owners, the TrailGuard K9 Tactical Dog Backpack Harness combines a secure walking harness with practical side storage for hiking, training, camping, travel, and everyday walks.

Whether you are heading to the trail, the park, or a weekend outdoor trip, this harness helps your dog carry small essentials while giving you better control than a standard collar.

Why Dog Owners Love It

  • Harness + Backpack in One: Designed for walking, training, and carrying small outdoor essentials.
  • Better Control for Large Dogs: A secure chest-and-belly fit helps keep the vest stable during movement.
  • Dual Side Storage Pouches: Carry treats, poop bags, keys, a small towel, folding bowl, or other trail gear.
  • Sturdy Top Handle: Helps guide your dog during travel, steps, car loading, crowded areas, or uneven paths.
  • Durable 600D Nylon: Rugged fabric made for outdoor walks, hiking, training, and daily use.
  • MOLLE-Style Webbing: Utility-style panels for patches or lightweight compatible accessories.
  • Adjustable Buckles: Helps create a more secure fit around the chest and belly.

Perfect For

  • Hiking and trail walking
  • Outdoor training
  • Camping and road trips
  • Large dog daily walks
  • Car travel and weekend adventures

Carry Trail Essentials

The dual side pouches are ideal for lightweight items such as treats, poop bags, a collapsible bowl, keys, small towels, and other everyday walking supplies. Keep essentials close without overloading your own pockets.

Designed for Secure Outdoor Control

The top handle gives you an extra control point when your dog needs help on stairs, near the car, or on uneven terrain. The chest and belly straps help the vest stay in place while your dog moves.

Size Guide

Please measure your dog before ordering. If your dog is between sizes, we recommend choosing the larger size for a more comfortable fit.

Customer photo review of Double-Decker Convertible Wheeled Travel Carrier

Great, I chose the whole set, and it's of very good quality. ☺️ . I'm just going to replace the bottom (in the plush cover, there is a very rigid cardboard, I really appreciate this recycling by the way). ), because my cats often have "leaks" during the journey, due to a hard plastic bottom. In my photos, it was assembled quickly; the second one looks loose, but when the steel bars are properly in place, the fabric is well stretched, so rest assured... arrived 1 month before the scheduled date .. I highly recommend this item, as well as the seller.

Customer photo review of Waterproof Quilted & Non-Slip Sofa Cover (Fitted)

I find the quality really great and it doesn't smell like chemicals at all. It's a bit larger than the area I wanted to cover, but you can easily tuck it into the crevices, so it only becomes noticeable if you look closely. Absolutely recommended for use as a dog blanket.

Customer photo review of Waterproof Quilted Oxford Non-Slip Car Seat Cover

I am really delighted with this purchase. It fits perfectly with another X3, the small space for the seat belts is great, and we were able to travel with our little dogs comfortably.

I had a question before ordering and customer service was incredibly helpful and quick to respond. My order arrived sooner than expected and the quality was honestly better than I anticipated. Everything from ordering to delivery was smooth. Really happy I found Tail Unity!

Ethan M., Denver, CO

Finally found a dog gate that my dog can’t constantly shove around. It feels heavy and well made, but still looks nice in the house. Installation was simple and the door is really convenient when I’m carrying something. Exactly what I needed for the bottom of our stairs.

Chloe B., Austin, TX

Our Labrador completely took over the new dog bed on the first day. He has plenty of room to stretch out and seems much more comfortable than he was on his old bed. I especially like that the cushion can be removed for cleaning. It’s become his favorite spot in the house.

Car rides used to be a struggle because my little dog would move around the entire back seat. Now she has her own spot and actually settles down for the drive. The cushion is soft, the seat feels secure, and getting it set up was really easy.

Michael R., Mesa, AZ

Traveling with two cats has always been a pain, so having separate compartments has been a game changer. I can roll the carrier through the airport instead of carrying everything, and the wheels move really smoothly. Both cats had enough room to stay comfortable during the trip.

Samantha L., Tampa, FL

I work unpredictable hours, so keeping my cat on a consistent feeding schedule wasn’t always easy. The automatic feeder has taken a lot of stress out of that. Meals are portioned out on schedule and I don’t have to worry about rushing home just to feed him. Such a useful addition to our routine.
