Blue Boston Terrier

A Blue Boston Terrier?!

Yep… you heard me right!

Just when you thought you knew about every Boston Terrier color

It’s probably not what you’re thinking— Blue dogs are more of a silver-ish grey color than sky-blue.

Read on to learn all about the different types of Blue Boston Terriers, their health problems, how much they cost, and more!

Blue is not an official Boston Terrier color…

The AKC only recognizes 5 colors for Boston Terriers. 

While Blue isn’t one of the AKC’s 5 official Boston Terrier colors, it’s definitely one of the most desired— and it’s probably not as “blue” as you’d first imagine…

Not all colors are equal

Some colors are prone to certain health issues— unfortunately, Blue is one of these colors.

Blue dogs (not just Boston Terriers) are prone to a skin condition known as Color Dilution Alopecia.

What makes Blue Boston Terriers Blue?

A mutation in the melanophillin gene (MLPH) causes pigments intended to be black to take on a silver/gray appearance. This is also known as a dilution gene. There are multiple variants for the color dilution gene that can give the Blue apperance.

Blue Boston Terrier Variations

There’s more than just plain “blue” Boston Terriers— some other variations of the Blue Boston Terrier include…

  • Blue
  • Blue Pied
  • Blue Fawn
  • Blue Merle
  • Blue Sable
  • Blue & Tan

How much is a Blue Boston Terrier?

The average Boston Terrier costs ~$1,200— a Blue Boston Terrier should cost about the same as any other Boston Terrier…
Blue Boston Terriers are rare!

You don’t see Blue Boston Terriers every day!

Considering the rarity of Blue Boston Terriers, some breeders will charge more than the average Boston Terrier for their Blue puppies— but others will charge the same as any other color… it depends on the breeder.

Not without controversy

Some consider these unofficial Boston Terrier colors to be “fad” colors— some breeders even mix their Boston Terriers with other breeds to create these “rare” colors.

This practice can sometimes result in certain health issues that would not be present in a purebred Boston Terrier.

For example, a 100% White Boston Terrier would be at a much higher risk of deafness than another color.

Blue Boston Terrier Health Problems

While Blue Boston Terriers are prone to all the same issues as every other Boston Terrier, they are uniquely affected by a condition known as Color Dilution Alopecia.

I have a blue Boston who will be one at the end of April , 2023. He has had no problems at all. His tcoat is beautiful and so so smart. I taught him to ring the bells on the door to go out in 3 days. This was the best thing he has done for me!!! We are now trying the skateboard!!! I am in love with my TuckerπŸ’™πŸ’™

Hi Cheryl,

So glad to hear that you've got yourself a wonderful Blue Boston Terrier. Sounds like you've got a smart one too!

I can't believe you were able to train him to ring the bell to go out β€” I wish my Frenchie would; she doesn't even bark lol.

We'd love to see him skateboarding! If he learns and you'd like to share a video with us, you can send it to us at

Best wishes to you and Tucker, FrenchieWiki
