Harness Parts, Handles & Straps

A simple, short, clip-on handle 

We’ve created this little clip-on handle for those that would like a simple grab handle added to the BAH, MSH, or LAH.

Most commonly used for pulling up from a seated position, or for occasional wheelchair pulling. 8″ overall length, with 5″ of triple-layered leather, creates approximately a 2-3″ handle.

(Will not fit BLD’s everyday working harness, the clips are too small for the D-rings.)

Made from layered, 5/8″ wide leather and stainless steel snaps just like BLD’s other leather harness handles. This grab handle can be used anytime you need the dog to pull with a quick tug, such as for climbing stairs, getting up from a seated position, and even pulling a wheelchair on occasion.

Stainless steel snaps are on each end and clip to the accessory D-rings on the BAH and MSH, or onto the top O-rings on the BAH and LAH.

Designed to fit only the indicated harnesses by Bold Lead Designs. Accessory strap only. Harness not included.

Replacement thumb screw bolts for the Mobility Support Harness; the bolts hold the handle on the harness. This is the “new style” that screws into the female nuts on your harness support bars for harnesses made AFTER December 2015.

Choose the set of hardware you prefer (we will add Teflon plumbers tape to each bolt so it stays snug):

• Complete set: Includes a pair of round thumb screw bolts, a pair of tee thumb screw wing bolts, and 6 rubber washers. Just like the kit that came with your harness.
• Round Bolts: A pair of round knurled thumb screws plus washers.
• Wing Bolts: A pair of tee thumb screws plus washers.
• Locking Bolt Kit: for those who want to install a set of bolts that do not come unscrewed. Includes wing bolts (Tee thumb screws) and locking wingnuts. Installation requires tools including hex key (Allen wrench) and channel lock plyers and patience.

Select size based on the thickness of the support bar.

• Standard support bars use the standard size bolts (for 1/8″ thick support bars).
• TALL handles need the longer bolts to fit the heavy weight support bars (for 1/4″ thick support bars). See photos for details.

Tips for using your MSH handle:

• Always loosen the bolts before folding the handle. Failure to do so may ratchet the right side too tight and cause it to lock up.
• Always tighten the bolts after raising the handle. Not too tight, just a little snug.
• Place the rubber washer on the bolt before screwing into the harness handle.
• Keep a spare bolt handy at all times.
• If the bolts want to loosen too much, apply some Teflon plumbers tape to the threads of the bolts.
• Consult your harness Owner’s Manual for more info.
• All thumbs screws are standard “quarter twenty” thread bolts: SAE 1/4-20

• • Belly Straps for the standard and XL size harnesses are1 1/4″ wide leather strap tapers to 3/4″ for buckles

Measure the Dog's Belly:

• First, locate the spot under your dog’s belly where his/her ribs come together and join the sternum (indicated in red on the diagram).
• Feel the dog’s side and find the back of his ribcage, then count 3-4 ribs forward. 
• Follow this rib down and palpate to find the notch where the deep part of his chest curves up toward the belly (flanks).  
• Bring the measuring tape under this point of the dog’s ribs, and pull the tape up and forward to the “sweet spot” behind the withers 
• The measuring tape must be snug. The measure will be at a diagonal angle. 
  

Pro Tip: 

Put the measuring tape under your dog and “see-saw” it back and forth while pulling forward toward the withers—this settles the tape nicely under the belly, and then bring both sides of the tape to the “sweet spot.”  

Avoid measuring vertically around the dog’s waist, or place the measuring tape so far back it reaches the dog’s flanks—both will yield inaccurate measurements. Usually, the belly and girth measurement are within 3 inches of each other.

Can you buckle the harness on your dog?

YES: use Option #1

NO: use Option #2

Strap refit option #1:

Use this method if the harness straps can buckle on your dog and fit reasonably well, but
there’s not enough room for adjustment in the future. You will measure to the hole that fits best. In the photos below, the pencil points to the adjustment hole that best fits.
1. Take note of which hole fits your dog best
2. Take the strap off the harness and lie it flat on a table
3. Measure the strap leather from the hole that fits best to the quick release latch. Measure only the leather (not the hardware).

Strap refit option #2:

Replacement belly strap for Mobility Support or Balance Assistance harness. 

Straps are 1" wide, and include with a 2" wide oval shearling sheepskin pad that slides onto the strap. 

NOTE: If you are unable to select the girth measurement, it is outside of the normal range for that saddle size. If you select OTHER, contact us and we'll help you verify the size you need. 

Please measure your dog; check out the refit guide for more details.

Measure the Dog's Girth:

• This measurement goes around your dog’s ribs, behind the front legs, at the deepest part of his chest.
• Start the measuring at the “sweet spot” behind the withers, go down under the deepest part of the dog’s chest and back around to the top.  
• The measuring tape should be mostly vertical, forming a complete circle around the dog’s chest.
• Measure snugly but don’t squish your dog. (With long haired dogs, be sure you’re measuring the dog’s body, not just their floof!)
