When it comes to walking your French Bulldog, the choice between a harness and a collar is not about fashion—it is about health. For this breed, a harness is the only safe option.
Why We Say “NO” to Collars
French Bulldogs are a brachycephalic (flat-faced) breed with a unique neck and airway structure. Using a collar with a leash can lead to serious medical issues:
- Respiratory Stress: Any tension on a collar puts direct pressure on the trachea (windpipe). This can cause gasping, chronic coughing, and long-term breathing difficulties.
- Spinal Protection: Frenchies have compact spines. A harness distributes the pull across the strongest part of the body—the chest—rather than the fragile cervical vertebrae (neck).
- The “Escape Artist” Factor: Because a Frenchie’s neck is often as wide as their head, they can easily slip out of a collar if they get scared or stubborn. A well-fitted harness keep them secure.
Sizing Your Puppy (2 Months +)
Finding the right fit is crucial for a growing puppy. If a harness is too tight, it restricts bone development; if it’s too loose, they can trip or escape.
| Age | Recommended Harness Size | Recommended Collar Size (ID Tags Only) |
| 8-10 Weeks (2 Months) | Size XS (Extra Small) | Size XS |
| 3-4 Months | Size S (Small) | Size S |
The Two-Finger Rule: You should always be able to fit two fingers between the harness and your puppy’s body. This ensures it is snug enough to be secure but loose enough for comfortable breathing and movement.
Important Note on Collars
We recommend using a collar ONLY for carrying an ID tag with your contact information. Never attach a leash to a collar for walking or training your Frenchie puppy.
