Guide for Chihuahuas and small dogs
Collars and harnesses for Chihuahuas
The right harness or collar for a Chihuahua should fit neatly without restricting movement. This guide helps you measure your dog, compare the options and find products with proportions suited to smaller dogs.
Fit comes first
What suits a Chihuahua?
Chihuahuas are small dogs with slender necks and compact chests, but body shapes vary considerably between individuals. Choosing the smallest size is therefore not enough. Collar width, harness adjustment and your dog's actual measurements all need to work together.
Small proportions
Collars and buckles should suit a smaller neck and feel comfortable rather than bulky against your dog's body.
Adjustable fit
An adjustable harness makes it easier to achieve the right fit around both the neck and chest.
Room to move
The harness should stay securely in place without rubbing under the front legs or restricting their natural movement.
Two different purposes
Collar or harness for a Chihuahua?
Many small dogs use both a collar and a harness. The best choice depends on the situation, your dog's body and how they walk on the lead.
Dog collar
A lightweight collar is useful for an ID tag, shorter walks and dogs that walk calmly on the lead.
- Choose a width that suits your dog's neck
- Check that the buckle is not too bulky
- Leave comfortable space between the neck and collar
Dog harness
A well-fitting harness spreads contact over a larger area of the body and can be a good choice for longer walks.
- Measure both the base of the neck and the chest
- Check that the harness does not rub under the front legs
- Make sure your dog cannot back out of the harness
How to measure
Measure your dog before choosing a size
Sizing can vary between models. Always use the product's size chart and your dog's current measurements.
Open the harness measuring guideMeasure the neck
Measure where the collar normally sits. Keep the tape close to the coat without pulling it tight.
Measure the chest
Place the tape around the widest part of the chest, usually just behind the front legs.
Compare with the right model
Compare the measurements with the size chart for the specific collar or harness you want to buy.
Check the fit
Try the product indoors and check that your dog can stand, walk and move naturally.
Tip: Measure your dog again even if you know their usual size. Coat, weight and different product models can affect the fit.

Frequently asked questions
Collars and harnesses for Chihuahuas
What harness size does a Chihuahua need?
You cannot choose a size based on breed alone. Measure the base of your dog's neck and their chest, then compare these measurements with the size chart for the specific harness.
Is a collar or harness better for a Chihuahua?
Both can work well. A collar can carry an ID tag and suit calm walks, while a well-fitting harness can be a good option for longer walks. Choose according to your dog's body and behaviour.
How should a harness fit a small dog?
The harness should stay securely in place without rubbing, pressing or restricting the front legs. Also check that your dog cannot back out of it.
How tight should a Chihuahua's collar be?
The collar should fit securely enough that your dog cannot slip out, without pressing against the neck. Always follow the product's measurements and fit recommendations.
Which breeds can use the Petit range?
Petit is designed for smaller dogs and may suit Chihuahuas and other small breeds. Your dog's own measurements are always more important than breed when choosing a size.
