Jack Russell is a breed of terrier developed in the United Kingdom in 1819 AD to hunt foxes. They were named after Reverend John Russell, who laid the basis of a line of terrier dogs, including Jack Russell. 

Contrary to Jack Russell, Beagle’s ancestors originated in the 5th century in Ancient Greece. Breeds such as the Harrier and the Southern Hound played a key role in establishing Beagle dogs. Beagle’s origin has been documented as far back as 500 AD. Beagles were mainly used for hunting since they could easily track down rabbits and other small animals.

Jack Russell vs Beagle: Size

A Jack Russell weighs between 11-17 pounds, while a Beagle weighs between 20-30 pounds.


Jack Russell terriers tend to be lighter and shorter than Beagle breeds. Both Jack Russell males and females weigh between 11-17 pounds and are approximately 10-15 inches tall. Their puppies weigh about 6 to 8 pounds when they are three months old. Jack Russell puppies are considered fully grown at 12 months.

Being larger and heavier than Jack Russell terriers, Beagle male and female dogs weigh between 20-30 pounds and are around 14-16 inches tall. Their puppies weigh about 7 pounds when they are two months old. Beagle puppies reach maturity at 18 months.

Jack Russell terriers have V-shaped ears that appear to be dropping forward. They also have almond-shaped eyes, which are dark in color and so full of life. As opposed to Jack Russell, Beagle dogs have luxurious floppy ears that blend very well with their medium brown or hazel eyes.

Jack Russell vs Beagle: Coat Texture and Colors

Another key difference is their coat texture and colors. Jack Russell terriers have three coat texture types: smooth, rough, and broken. They are white in color with either black or tan patterns.

Beagle breeds have smooth coat texture. Beagle dogs come in various colors, but the most common one is white with tan or black markings, or a combination of all of these three colors like in Parson Russell terriers. Beagles are technically multi-colored dogs, and you can hardly find a single solid color on them.

Jack Russell vs Beagle: Life Expectancy

Jack Russell and Beagle breeds have a long-life span. The life expectancy of a Jack Russell is typically around 12-14 years. Beagle dogs have a longer lifespan, ranging between 12-15 years. Depending on their diet, environment, and other facts, both breeds may or may not exceed their life expectancy range.

Jack Russell vs Beagle: Temperament

Jack Russell Terriers are more aggressive than Beagle breeds.


Jack Russell terriers and Beagle breeds have very different personalities. Jack Russell breeds are well known for their aggressive temperament. They are not as friendly as Beagle dogs. Jack Russell dogs are very territorial and protective. They tend to be fiery towards other dogs and strangers. They are also mischievous, even around children.

On the contrary, Beagle breeds are very friendly, sociable, and good-natured. They get along well with children and other dogs. Besides, they can quickly establish contacts with people they know and those they don’t know. That’s why they are suitable for family pets and first-time dog owners.

Jack Russell vs Beagle: Litter Size

Jack Russell terriers can give birth to approximately 4 to 7 puppies in one litter depending on several factors, such as Jack Russell’s health status, genetics, age, and size. Beagle breeds can give birth to about 4 to 6 puppies in one litter.

Jack Russell vs Beagle: Breed Focus

Jack Russell terriers cannot be distracted easily, especially when barking at someone or something. They remain focused on the intruder. Calming them requires a lot of time and skills. They pace up and down during such times. Therefore, they must be given treats until they calm down.

Compared to Jack Russell terriers, Beagle breeds can be easily distracted. As a result, training them requires a lot of time and perseverance because they keep shifting their attention to something else from time to time.
