1️⃣ Measuring for a Dog Collar

1. Wrap a soft tape around the base of the neck (where a collar naturally sits).
2. Add two fingers of space between tape and neck for comfort.
3. Compare the number to the product’s size chart; pick the size where your measurement sits near the middle of the range.

For beach days and rainy trails, try a wipe-clean option: Waterproof & Odorless Biothane Dog Collar.

2️⃣ Measuring for a No-Pull Harness

1. Chest (Girth): Measure the widest part of the chest—just behind the front legs.
2. Neck (if required): Measure around the lower neck where the harness rests.
3. Adjustability: Choose a harness with multiple adjustment points so you can fine-tune the fit.

Need extra control without pressure on the neck? Shop our No-Pull Dog Harness with 3 leash clips for versatile training and everyday walks.

• Signs of a good fit: you can slide two fingers under any strap; harness doesn’t rub armpits; no shifting when your dog moves.
• Signs it’s too tight: chafing, matting fur, heavy panting from restriction.

3️⃣ Picking the Right Leash Length

• 4–6 ft: Best for city walks and close control.
• 8–10 ft: Roomier strolls in open spaces.
• Training leads (15–30 ft): Perfect for recall practice.
