How to choose an escape-proof harness
There are few things more frightening than watching your dog slip backwards out of a harness.
Whether your dog is nervous around traffic, reactive to other dogs, a rescue still building confidence, or simply a four-legged Houdini, choosing the right harness can make walks safer, calmer and much more enjoyable for both of you.
At Be More Bob we’ve helped lots of dog owners find a safer, more secure harness setup, especially for nervous dogs, sighthounds, reactive dogs and expert escape artists.
Here’s what to look for when choosing an escape-proof harness.
First things first - a harness only works when it's properly fitted
The problem we see more often than not, is that the dog's harness is too loose. Your harness must sit snug (not tight) and fit properly around your neck, chest (and ribs, if a 6-point harness).
Fit, how you handle your dog, and your dog’s body language matter just as much as the harness itself.
The right harness:
- gives you more control
- improves comfort and confidence
- buys you valuable time if your dog panics
A well-fitted harness can absolutely transform walks with anxious or reactive dogs.
What makes a harness harder to escape from?
The biggest thing to look for is:
A second strap behind the rib cage - or, as it's sometimes called, a six point harness (as you can adjust it at six points)
Dogs usually escape harnesses by reversing backwards and slipping their shoulders out.
Harnesses with a second belly strap sitting behind the deepest part of the chest, makes it far more difficult for dogs to back out. This style is commonly recommended for escape artists and nervous dogs.
See how the belly straps sit behind the ribs, and when fitted correctly can't be pulled forward...

Ruffwear Flagline six point harness
This design is especially useful for:
- reactive dogs
- rescue dogs
- sighthounds (as this harness really suits long dogs with with deep chests)
- slim-bodied breeds
- dogs frightened by loud noises
- dogs new to harnesses
The importance of fit
Even the best harness in the world won’t work properly if it doesn’t fit correctly.
A secure harness should:
- sit snugly without rubbing
- allow full shoulder movement
- not rotate around the body
- stay secure when your dog backs up
- allow you to fit two fingers comfortably underneath straps
Too loose = escape risk.
Too tight = discomfort and restricted movement.
We always recommend measuring carefully and checking adjustment points regularly, especially for fluffy dogs whose coats can disguise poor fit. If your dog gets groomed, make sure to adjust the fit of your harness after your dog has lost its furry padding!
Why we recommend the Ruffwear Flagline Harness
The Ruffwear Flagline Harness is one of our favourite choices for dogs prone to slipping harnesses. It’s specifically designed with:
- a secure multi-strap design
- lightweight construction
- excellent adjustability
- a supportive handle
- a second belly strap for extra security
It’s become especially popular with owners of:
- nervous rescues
- reactive dogs
- sighthounds
- agile breeds like collies and staffies
We’ve also found it brilliant for hiking and adventure dogs because it’s secure without being bulky. The Flagline is one of the harnesses most commonly recommended by dog owners dealing with escape behaviour.

Ruffwear harnesses are made for adventures. Get them wet, take them hiking, walking, running. They are durable, comfortable and most importantly, safe.

Another excellent option: Ruffwear Web Master
The Ruffwear Web Master Harness is another fantastic choice for dogs who need extra security.
The Web Master has developed a strong reputation amongst owners of escape artists because of its supportive structure and secure fit.
It’s particularly useful for:
- strong pullers
- nervous dogs
- dogs recovering from injury
- hiking adventures
- dogs needing lifting assistance
The sturdy handle is also incredibly useful in busy areas or difficult terrain.
We often sell the Web Master to senior dogs who need a little lift now and again.


Should you use a collar as backup?
For particularly nervous dogs, many trainers recommend using:
- a harness
- plus a secure collar
- connected with a safety clip or double-ended lead
This creates a backup connection if your dog somehow slips one piece of equipment, but it's really a personal choice. Your Ruffwear harness can be worn alone and has attachment points for your security tag.
For reactive or fearful dogs, this extra layer of safety can provide huge peace of mind, but equally you can rely on your Ruffwear harness alone if you prefer.

Signs your dog may need a more secure harness
Your dog may benefit from an escape-resistant harness if they:
- reverse suddenly on walks
- spook easily
- panic around traffic
- react to dogs or people
- have slipped a harness before
- flatten themselves when frightened
- have a deep chest and slim waist (this shape of dog is more prone to being able to slink out of a harness)
- are newly adopted or still settling in
Remember: even confident dogs can panic unexpectedly.
Don’t forget confidence building
A harness is only part of the picture.
For nervous dogs especially, confidence-building matters just as much:
- avoid overwhelming environments
- allow sniffing and decompression
- walk at your dog's pace
- reward calm behaviour
- use positive reinforcement
- keep walks predictable where possible - dogs LOVE routine
A comfortable, secure harness helps your dog feel safer and that confidence often transfers into calmer walks over time.
