Here are the home tests we recommend at www.bostonmadepets.com.

✅ Test #1: The Two-Finger Rule (But Done Correctly)

Most people have heard “two fingers should fit under the strap.”

That’s true — but only if you’re testing the right spot.

Check these points:

• under the chest strap (behind the front legs)
• under the neck strap (but not pressing the throat)
• under any strap that rests across fur and skin

Pass = two fingers slide under with slight resistance

Too tight = you can’t get fingers under without force

Too loose = fingers slide easily and straps move around freely

✅ Test #2: The Shoulder Freedom Test

This is the one most brands never talk about.

Your dog’s shoulder blades must move freely — especially when walking fast, running, climbing, or jumping.

How to test:

1. Put harness on
2. Have your dog walk forward normally
3. Watch the front legs and shoulders

Signs it’s too restrictive:

• short stride
• stiff movement
• “bunny hopping” (especially small breeds)
• dog stops and sits or refuses to walk
• dog suddenly becomes “lazy” only when harness is on

At www.bostonmadepets.com, we’re big on building wearables that move with the dog — not against them.

✅ Test #3: The Armpit Rub Check

A harness should never ride in the armpit.

What to check:

• After 5 minutes of walking, look at underarm area
• Separate the fur gently
• Check for red skin or friction

Red flags:

• redness
• missing fur
• wetness / irritation
• your dog licking the area repeatedly
• hesitation when you touch the harness straps

If that’s happening, don’t “wait and see.”

The fix is usually: different size, different adjustment, or a different harness shape.

✅ Test #4: The Pull and Shift Test

If your dog is a puller at all, the harness must stay stable.

Test it:

• hold leash like normal
• gently create tension
• observe the harness

Pass = stays centered and stable

Fail = slides sideways, twists, rides up

Twisting is not just annoying — it’s a sign that straps are applying uneven pressure.

At www.bostonmadepets.com, fit stability is one of our top priorities because stability equals comfort.

✅ Test #5: The Escape Test (VERY important)

This is the one that can prevent heartbreak.

Do this safely indoors:

• harness on
• hold chest straps
• allow your dog to back up slowly

If the harness can slip off their head:

• it’s too loose
• or it’s the wrong style for your dog’s body type

Some dogs (especially slim-chested breeds and anxious rescue dogs) need escape-resistant fitting more than others.

Signs Your Dog’s Harness Is Too Tight

Here’s the straight checklist.

If your dog shows any of these signs, the harness is likely too tight:

• heavy panting within minutes (when not hot)
• harness leaves deep indentations in the fur
• dog freezes when harness is clipped
• dog tries to chew or scratch it off
• red skin after removal
• decreased interest in walks (when harness is on)
• stiffness or short stride

If you’re seeing those signs, it’s time for an adjustment or a better fit.

Signs Your Dog’s Harness Is Too Loose

Loose harnesses create:

• chafing
• shifting
• twisting
• anxiety (because it feels unstable)
• and worst of all — escape potential

Signs it’s too loose:

• harness slides to the side
• dog can step out of it
• chest panel shifts left/right
• you can pull the straps away easily
• the harness rides up toward the neck during walking

How to Adjust a Harness the Right Way (Simple Method)

At www.bostonmadepets.com, we recommend adjusting harnesses in this order:

Step 1: Start with the chest strap

Make sure it sits behind the front legs, not in the armpits.

Step 2: Adjust the neck/upper strap next

Keep it away from the throat — you want it on the upper chest.

Step 3: Check symmetry

Left and right straps should match.

Step 4: Re-check after a 2-minute walk

A dog’s body moves differently in motion than standing still.

Why Boston Made Pets Cares So Much About Fit

Because fit is not just physical — it’s emotional.

When wearables fit well:

• dogs move naturally
• dogs act confident
• walks feel easier
• owners feel safer
• and dogs stop resisting getting dressed

At www.bostonmadepets.com, we build wearables with a long-term goal:

Make comfort the standard — not a luxury.

Because every dog deserves gear that feels like it was made for them.

Final Thought: Fit Is Love in a Practical Form

There’s something powerful about caring enough to get the fit right.

It’s saying:

• “I want you comfortable.”
• “I want you safe.”
• “I want this to feel good for you.”

And that’s what Boston Made Pets exists for.
