The ‘Frenchton’

The Boston Terrier French Bulldog cross breed, often referred to as the “Frenchton,” is a hybrid dog resulting from the crossing of a Boston Terrier with a French Bulldog. This crossbreed has gained popularity in recent years due to its unique appearance and charming personality.

Frenchtons often inherit a mix of physical features from both parent breeds. They may have a stocky and compact body like French Bulldogs, with a short muzzle, erect ears, and a wrinkled face. Their coat can vary in color and pattern, and they may have a short, smooth coat like both parent breeds.

These hybrid dogs are known for being affectionate, friendly, and sociable. They often get along well with children and other pets, making them excellent family dogs. They may also inherit a playful and energetic nature from both parent breeds, enjoying interactive playtime with their owners.

If you own either breed, let me know how they measure up to these stats, I’m very interested to know.

  1. Perfectly Said. You described both breeds to a T! 🙋‍♀️ from a 4 time Boston Terrier owner, and Godmother to a French Bulldog.

    1. Oh thank you so much. I’ve never actually owned either but they are on my doggie bucket list. It’s nice to know I got my research correct from someone who really knows both breeds. Thank you for dropping by.

  2. We have a Boston. He’s had a lot of health problems. He was very hard to housebreak, he had some severe and costly digestive problems. If he drank more than a little bit of water at a time he would throw it right back up. These issues seemed to have resolved themselves as he has entered his senior years. However now his back legs have become weaker (walks like he’s drunk). This also has led to some loss some bowel control. He doesn’t like children, or other dogs. In spite of all we love him dearly and he loves us. He is at my side every minute of the day.

    1. Poor little man! It sound like he sees you as his ‘security blanket’ and when he’s with you he feels safe, Thank you for sharing your story.
