What Makes the Best Puppy Harness?
Not all harnesses are created equal. The best puppy harness should offer:
โ
Adjustability โ Puppies grow fast, so an adjustable harness extends its usability.
โ
No-Pull Support โ A front-clip harness can help train puppies not to pull.
โ
Comfortable Fit โ Padded, lightweight materials prevent chafing.
โ
Durability โ Sturdy materials ensure the harness lasts through puppyhood.
โ
Reflective Features โ Enhances visibility for nighttime walks.
โ
Easy On & Off Design โ Step-in or clip-on designs reduce stress when putting it on.
At Bailey & Coco, our Trail & Glowยฎ Harness is designed with all these features, ensuring a perfect fit for all breeds.
How to Measure Your Puppy for a Harness

1๏ธโฃ Neck Measurement โ Use a soft measuring tape around the base of your puppyโs neck.
2๏ธโฃ Chest Girth โ Measure around the widest part of their chest, just behind the front legs.
3๏ธโฃ Weight Consideration โ Some harnesses list weight ranges, so check the brandโs sizing guide.

What Size Harness for a Puppy?

Puppy harnesses need to be adjustable to accommodate growth. Hereโs a quick breakdown:
- 8-week-old puppies ๐ถ โ Measure the neck and chest and match them to the chart. Very small breeds usually start in XXS or XS, but never go on age alone: two puppies of the same age can be two sizes apart.
- Small breeds (e.g., Dachshund, Chihuahua) โ Stick with XXS, XS or S, decided by the measurement rather than the breed.
- Medium breeds (e.g., Cockapoo, Cocker Spaniel) โ Opt for S-M harnesses.
- Large breeds (e.g., Labrador, Golden Retriever) โ Start with M-L harnesses.
๐ก Tip: If your puppy is between sizes, size up and adjust the straps for a snug fit.

Best No-Pull Harness for Training Puppies
Many puppies pull on the lead, making walks stressful. A no-pull puppy harness can gently correct this behavior.
What is the Best Harness for Training a Puppy?
A front-clip harness (like our Trail & Glowยฎ Harness) discourages pulling by redirecting your puppyโs movement.
๐น Why it works: Instead of pulling forward, your puppy will be guided to the side, helping with lead training.
๐น Best for: French Bulldogs, Labradors, Golden Retrievers, and Cockapoos, which tend to pull more.
How to Put a Harness on a Puppy Without Biting
Puppies often resist their first harness. Make the experience positive!
๐พ Step 1: Let them sniff the harness before putting it on.
๐พ Step 2: Reward them with treats when they interact calmly with the harness.
๐พ Step 3: Slowly clip or slip the harness onโdonโt rush!
๐พ Step 4: Ensure a snug but comfortable fitโtwo fingers should fit between the harness and your puppyโs fur.
๐พ Step 5: Let them wear it around the house before heading out for a walk.
๐ก Pro Tip: If your puppy bites the harness, distract them with a chew toy or treat.

| Prevents neck strain | โ No | โ Yes |
| Discourages pulling | โ No | โ Yes |
