Tools Needed for Measurement

  • Soft Measuring Tape: A soft measuring tape is the most appropriate tool for measuring a French Bulldog’s neck as it contours to the dog’s shape and accurately measures it. Ensure it’s flexible to wrap around the dog’s neck easily.
  • Paper and Pen: Jot down the measurements immediately to ensure accuracy and avoid forgetfulness.
  • Helper: Sometimes, having an extra pair of hands can be helpful, especially if the French Bulldog is squirmy or impatient.

Step-by-step Process of Measuring the Neck

  • Position the Dog: Have the dog stand or sit relaxed. Ensure the dog is calm to get an accurate measurement.
  • Place the Tape: Wrap the soft measuring tape around the base of the neck where the collar typically sits. It should be snug but not tight.
  • Read Measurement: Note the measurement where the end of the tape meets, ensuring there is room for two fingers to slide between the tape and the dog’s neck for comfort.
  • Record the Measurement: Write down the measurement immediately to refer to when selecting a collar size.

Tips for Accurate Measurement

  • Repeat Measurement: Measure a couple of times to ensure consistency and accuracy.
  • Consider Growth: If dealing with a puppy, consider their rapid growth and that you may need to upsize the collar within a short period.

Types of Collars Suitable for French Bulldogs

Standard collars are the conventional type used for identification and restraint. They can be made of various materials, including leather and nylon, and are typically adjustable to fit the neck comfortably. However, owners must ensure they’re not too tight or loose to avoid discomfort or escape.


Harnesses encircle the dog’s chest, back, and shoulders, offering better control and reducing strain on the neck. They are particularly useful for French Bulldogs, a breed prone to brachycephalic syndrome, as they distribute pressure evenly, minimizing the risk of breathing difficulties.

Specialized Collars for Training or Health Issues

These are designed to address specific needs, such as behavior correction or medical conditions. For instance, some collars help control pulling, while others are tailored for dogs recovering from surgery. Choosing depends on the individual French Bulldog’s needs and should be discussed with a vet or professional trainer.

When is Collar not the right option for my Frenchie?

There are instances when a collar might not be the right option for your Frenchie. If your dog has respiratory issues or is prone to Brachycephalic Obstructive Airway Syndrome (BOAS), a collar can exacerbate the problem by putting pressure on the throat and restricting airflow. Also, a collar can lead to neck injuries or chronic pain if your Frenchie is a puller.

Puppies, especially, might find collars uncomfortable or frightening initially, and an alternative like a harness could be a gentler option. Also, if your French Bulldog has skin issues or allergies or is recovering from a neck injury or surgery, avoiding a collar temporarily might be advisable.

Risk Associated with Choosing the Wrong-Sized Collar for a Frenchie

  • Discomfort and Irritation: A collar that is too tight can cause discomfort and skin irritation. The constant rubbing against the skin can lead to rashes, hair loss, and open sores, making your Frenchie uncomfortable and stressed.
  • Breathing Difficulties: French Bulldogs are brachycephalic breeds with shorter snouts and respiratory tracts. A tight collar can exacerbate breathing difficulties, leading to potential respiratory distress, especially during walks or activities.
  • Injury Risk: Wrong-sized collars can lead to injuries. If it’s too tight, it can cause muscle strain or damage to the neck and spine. In severe cases, it can lead to tracheal collapse, a dangerous emergency requiring immediate veterinary care.
  • Escaping Risk: On the other hand, a collar that is too loose is equally harmful. It increases the risk of your Frenchie slipping out and escaping, leading to potential accidents or the dog getting lost.
  • Ineffective Training: An ill-fitted collar undermines training efforts for those using collars as a training aid. It either causes discomfort, leads to adverse behavior, or is too loose to provide adequate control or communication.
  • Choking Hazard: A too tight collar, or even one that’s too loose and gets caught on something, can present a choking hazard. Ensuring the collar allows for comfortable breathing while being secure enough not to snag on objects is essential.
  • Behavioral Issues: Continuous discomfort from an ill-fitting collar can lead to behavioral issues. Your French Bulldog might become irritable, aggressive, or anxious, impacting its overall temperament and well-being


Is a collar safe for a French Bulldog puppy?

What are the alternatives to French Bulldog Collars?

Other options include head halters or body belts.

Collar vs Harnesses: Which is better?

For French Bulldogs, harnesses are often recommended over collars. Frenchies have a brachycephalic skull structure, making them prone to breathing difficulties. Harnesses ensure no pressure on the neck and throat, reducing the risk of respiratory stress and providing better control during walks.

Which collar material is best for my Frenchie?

Collars made of soft, breathable, durable materials like leather or padded nylon suit French Bulldogs. These materials reduce the risk of irritation and ensure comfort. Always check for adjustable features to ensure a perfect fit as your Frenchie grows or gains weight.

Can French Bulldogs wear collars all the time?

It’s advisable to remove the collar when the French Bulldog is indoors or during play to reduce the risk of getting caught on something and causing injury. Ensure the collar is comfortable, well-fitted, and checked regularly for signs of wear and tear if worn frequently.
