Boy Dog Names That Start With J

A biblical place name with trumpeting verve and strength.

Jax is the Dex-Jex-Pax type of x-ending cool -- possibly too cool -- variation of Jack or nickname for Jaxon or Jackson.

Immortal through its association with the ancient Caesar (it was his clan name), Julius may still lag behind Julian, but is definitely starting to make a comeback, and in fact feels more cutting edge, in line with the current trend for Latin -us endings.

Though this feels like a modern invention, Jay has been in use for centuries. Early Jays often were named in honor of founding father John Jay, whose surname derived from the jaybird. A popular mid-century choice, Jay was in the Top 100 from 1956 to 1970. In the last couple of decades he was replaced by such more elaborate forms as Jayden, Jaylen, and Jayce. But Jay could make a comeback in tandem with cousins May, Kay, Fay, and Ray.

While Jadon is the authentic biblical name, Jaden is by far the more popular spelling, first noticed when Will and Jada Pinkett Smith used it for their now grown (and famous) son. It has since swept the country for both sexes, with a wide variety of spellings and rhyming cousins.

Justin has been widely popular since the 1980s, when parents were seeking a fresher 'J' boys’ name to replace Jason, Jeremy and Jonathan. It's been dipping in popularity a bit in recent years but it reached as high as Number 9 in 1990. At this point it's Justin that is suffering from overexposure.

A variation of Jenson, which is actually more popular than the original in the United States. This spelling also holds the distinction of being the most common surname in Denmark.

The cool form of James in the 1970s and '80s for both sexes. Still a more stylish short form than Jimmy, though many parents will want to call James by his entire, not-very-long name.

The mostly Americanized version of Geoffrey was a trendy mid-century hit, with nickname Jeff the epitome of cool. Jeffrey entered the pop list in 1934 and was a Top 20 name from the mid-fifties to 1978.

Jethro, though the biblical father-in-law of Moses, has suffered for a long time from a Beverly Hillbilly image, but some really adventurous parents might consider updating and urbanizing it and transitioning it into the hip o-ending category.

Jaxon has been mostly climbing in popularity since it entered the Top 1000 in 1997, proving that many parents have decided to rev up the cool factor of Jackson by giving it this streamlined spelling. (Though we still prefer the original.)

Jaunty, to say the least, Jonty might be an option if Johnny feels too old school. It has been noticed most often on the playing fields, as in U.K. rugby player Jonty Parkin (born Jonathan) and South African cricketer Jonty Rhodes (Jonathon).

Jagger is a swaggering Rolling Stone of a name that's been picked up by a number of fellow celebs, including Lindsay Davenport and Brett Scallions--while Soleil Moon Frye pulled a gender switch when she bestowed it on her daughter. It's edgy with a touch of danger.

Unusual letters like X and Z are often considered badass and cool, so by that logic, does having two Xs in one name make it next level awesome? This seems to have been the thinking of the parents to nearly 3000 babies named Jaxx in America since the spelling first came into use in the 90s.

This super-charged variation of Jett is on the rise -- along with the unlikely newcomer Jetson.

In Paris, it's charming, but in America, it's still Jean, as in blue jean. Or Aunt Jean.

Jupiter's partner Juno has entered the mainstream, so it's possible that her divine mate could follow. But not necessarily for boys — Jupiter is currently mostly female in the US, thanks to its similarity to Juniper. Stars including Ed Sheeran and Ashley Tisdale recently welcomed daughters named Jupiter, which could shift the balance even more towards the girls.

Actor Joaquin Phoenix (brother of River, Rain, Liberty and Summer) highlighted this one, then Kelly Ripa began talking about younger son Joaquin on her daily TV show, and presto—it's now one of the hottest and most appealing multicultural baby boy names.

Quintessentially common last name makes distinctive if problematic first, given to nearly 100 babies in the US in the most recent year counted.

Jerry is one of those short forms that, like Mike and Debbie, rose to popularity on the coattails of their formal versions. The equivalents today are nickname names like Ellie and Theo.
