I have an 11 mo old French Bulldog named Phoebe, a true skeptic when it comes to harnesses. We have sent back about 4? Be it sizing or Phoebe clearly not having it. BUT! She gets excited to wear this one! I am truly not making this up, although it feels like it--was definitely not setting any expectations around that. I personally wanted the corduroy and so glad us girls agree ;) The color combo looks SO good on her light fawn/tan coloring. **I know all too well that sizing can be hard with frenchies. I purchased a size S (small) and it is perfect. More details on sizing, hope this helps:
Chest: 16 in
Neck: 12 in
Weight: 22 lbs
*I have every strap pulled as tight as possible, room to grow (yay!)
