Buying a harness online sounds easy, until it arrives and it is either so loose your dog slips right out of it, or so tight that your poor baby refuses to walk. Both situations are common, and both are completely avoidable. The secret is just one thing: measuring your dog properly before you order.
Do not worry, this is simple. All you need is a soft measuring tape (the cloth kind tailors use) and two minutes. Let me show you exactly how.
Why a harness is better than a collar for walks
Before we measure, a quick word on why harnesses are worth it. When a dog pulls on a collar, all that pressure goes straight onto the neck and throat. Over time this can hurt the windpipe, especially in small breeds and flat-faced dogs. A harness spreads the pressure across the chest and shoulders instead, which is much safer and far more comfortable.
Harnesses also give you better control on busy Indian roads and during walks, and they reduce the chance of your dog slipping away and bolting, which every pet parent fears.
The two measurements that matter
Almost every harness sizing depends on two numbers. Get these right and you are sorted.
1. Chest girth (the most important one)
This is the measurement that decides everything. Wrap the measuring tape around the widest part of your dog’s chest, which is just behind the front legs. Keep the tape snug but not tight. This circumference is your chest girth.
2. Neck girth
Measure around the base of the neck, where a collar normally sits, just above the shoulders. Again, snug but comfortable.
Write both numbers down in centimetres. When in doubt between two sizes, go by the chest girth, because that is what holds the harness in place.
The two-finger rule
Here is the simplest fit test in the world. Once the harness is on, you should be able to slide two fingers comfortably between the strap and your dog’s body. If you cannot fit two fingers, it is too tight. If there is loads of room and the harness shifts around, it is too loose. Two fingers, that is the sweet spot.
A rough size guide for Indian breeds
Every harness is a little different, so always check the brand’s chart, but here is a general idea:
- XS / S: Pomeranian, Shih Tzu, small Indie pups, kittens and puppies.
- M: Beagle, Cocker Spaniel, small to mid Indies.
- L / XL: Labrador, Golden Retriever, German Shepherd and other large breeds.
Puppies grow fast, so if you have a young pup, look for an adjustable harness with multiple buckle points. It will last much longer as your baby grows. You can browse adjustable options in the Dupih collars and harnesses collection.
Common fitting mistakes to avoid
- Measuring over thick fur: Press the tape gently down to the body, especially for fluffy dogs, or your reading will be too big.
- Measuring a wriggly dog: Do it when your dog is calm and standing, maybe after a meal or a walk.
- Ignoring adjustability: An adjustable harness is far more forgiving than a fixed one.
- Buying only by weight: Two dogs of the same weight can have very different chest sizes. Always measure.
Getting your dog used to the harness
Some dogs love their harness instantly, others act like you have put a saddle on them. If your dog is unsure, go slow. Let them sniff it first. Put it on for a few minutes at home with a treat, then take it off. Repeat over a few days, slowly increasing the time. Soon your dog will link the harness with walks and treats, and will get excited the moment you pick it up.
Quick FAQ
Harness or collar, which is better?
For walks, a harness is safer because it takes pressure off the neck. A collar is still handy for holding ID tags at home.
My dog keeps slipping out of the harness. Why?
It is almost always too loose around the chest. Re-measure the chest girth and tighten using the two-finger rule.
How tight should a dog harness be?
Snug enough that it does not shift around, loose enough to slide two fingers underneath the straps comfortably.
Can puppies wear a harness?
Yes, and it is actually great for leash training. Just pick an adjustable one and re-check the fit every few weeks as your puppy grows. Want to compare with a collar? See our guide to the best collars and safe fit for everyday wear.
Final thought
A well-fitted harness makes walks safer and far more enjoyable for both of you. Measure the chest and neck, follow the two-finger rule, and choose adjustable if your dog is still growing. That is all it takes.
