Jack Russell Terrier vs Chihuahua - Breed Comparison

Quite a bit of the Chihuahua’s history is shrouded in mystery, and there are different versions about its origins.

While historians speculate, most will agree that the tiny dog hails from Mexico. The UK Kennel Club considers the smooth- and long coat Chihuahuas as 2 distinct breeds.It was in 1904 that the Chihuahua became a registered breed by the American Kennel Club.

Chihuahua is actually the name of a state in Mexico, and it is amazing that Chihuahua specimens were found way back in the 1800's already. Today the Chihuahua is a very popular dog breed in several countries.

The popular Jack Russell Terrier was developed in Devonshire in the south of England in the late 1800's so as to hunt foxes.

Often believed to be the Parson Russell Terrier, the Jack Russell Terrier was developed by Parson John Russell. This is where the dog gets his breed name from. Some people get the Jack Russell Terrier a little bit mixed up with the Parson Russell terrier, when it fact its actually a different breed, but sharing a common ancestry.

The Jack Russell Terrier is smaller than the Parson and bigger than the Russell Terrier. The breed became known in the U.S. by the 1930s and the Jack Russell Terrier Association of America wanted recognition by the American Kennel Club, which was granted in 2000.

The small Chihuahua stands at about 15 – 23 cm and he weighs about 1,5 – 4kg.

You’ll notice that he shivers when he is excited or when he is cold or frightened. Some people buy him a jersey to don on cooler days. With this tiny toy dog, you get a short- and a long coated Chihuahua.

Temperament:

The Chihuahua is such an alert, fun-loving, feisty little dog, and though he may appear to be an ideal pet for children, he actually isn’t. He is too dainty and frail, and a child, during play, could accidentally crush him.

It’s a pity though because he just loves being around his human family. He is also a highly strung dog, and given the chance, he’ll nip and even bite during games. It is why socialization and training are considered important for the Chihuahua.

Just like with children, how you raise and treat your Chihuahua will determine how he turns out. He is such a sweet little dog that training and socialization can remove these unwanted characteristics. He is very intelligent and responds well to training.

The Jack Russell Terrier is a small dog that weighs between 6 and 8kg and stands at between 25 – 38cm. The body length of the dog should be in proportion to the height.

He is essentially a white dog with orange or fawn colored patches. The coat is mostly smooth and short, but the coat can also be longer and rough or it can be broken which is a combination of rough and smooth. Regardless of coat type, they are dense, double coats which will require brushing at least twice a week to remove loose hairs. He may also be tri-colored such as being white with black and tan patches.

He has alert, bright dark brown eyes and ears which are somewhat erect and which flop over at the tips. The tail has always been traditionally docked, giving him an attractive, compact look about him but unfortunately the tail is often left long on the dog these days.

Temperament:

Your Jack Russell Terrier is a lively, tenacious, bold, fearless, feisty, cheeky, confident, independent, intelligent and full of life dog. He is super energetic and exuberant, spirited and full of personality.

There are some dog owners who are exhausted by him and would prefer a more quieter dog breed as their companion. Nonetheless he has some excellent characteristics such as being a totally devoted and loving dog.

It is why it is a good idea to have him trained and socialized as it calms him down and makes him more obedient. He is very intelligent and training him will be easy.

Small and feisty, the Chihuahua’s personality isn’t set in stone, and the tiny dog can be either shy and timid or he can be social, confident and jaunty.

They're always loyal and affectionate to their human owners, but they don’t get on too well with- and are wary of small children who aren’t disciplined and who could hurt them.

With his big eyes and big ears together with his comical antics, they can be a source of entertainment for their human owners. He is easy to train too and even though he is small, he doesn’t think he is, and he is willing to use his big personality to make you a loving, loyal and devoted companion.

With loads of vibrant personality, the energetic Jack Russell Terrier has got so many wonderful characteristics to his name – devotion, intelligence, charming, lively, playful and he is an entertainer – you’ll always be laughing a him.

Some common dog disorders you might want to be aware of are -

Eye disorders:

Lens luxation is actually a common hereditary disorder in these dogs, but even so, with good care, your dog isn’t likely to battle with it. What happens is that the lens in the eye becomes displaced. There are two types, with Posterior luxation being the lesser severe one.Treatment is available.

Musculoskeletal conditions:

Patellar luxation is an hereditary disorder affecting the knees of the dog. The kneecap slips off the groove where it sits and you may notice your dog running while holding his hind leg in the air. It can sometimes slip back in place and then you see your dog running in his usual way. It becomes more serious when it affects both legs.

Diet:

Always make sure to choose a high-quality dog food for your Chihuahua as this will keep him in tip-top health. A healthy Chihuahua can live to be 20 years of age. Speak to a veterinarian for recommendations on the best type of food to feed your tiny pet.

Exercise:

The Chihuahua may well be the smallest toy sized dog breed, but don’t be mistaken – he has plenty of energy and is constantly prancing around. He is more than capable of living in a small apartment, but even so he needs to be taken outside every now and then for a game or a walk.

Be careful with your small pet though, as too much exercise can lead to elbow- and hip dysplasia.

Grooming:

The Chihuahua is a moderate shedder with Spring being their heavier shedding period. Because of his small size, you won’t be bothered by too much hair. The short haired Chihuahua is easy to maintain and with a rubber brush, you can brush him gently twice a week.

You’ll also need to clip his nails and if you can’t manage this your vet can also help you.

Exercise:

The Jack Russell Terrier isn’t just a small dog that can be left to his own devices. He will need proper training and socialization early in life to make him obedient and better to get on with.

He may be a small dog, but he certainly won’t do in the city where he is cooped up in a place with a handkerchief of a garden. He needs lots of space to run and play. He wants his human family to join in with walks, hikes, ball games and swimming.

Diet:

You can buy excellent commercially manufactured dog food which caters for energetic small dog breeds like the Jack Russell Terrier.

Once you have selected the best one for your pet, with dry kibble being better in terms of dental health - you can also add in some brown rice, vegetables and cooked chicken. This is highly beneficial to all dog breeds. A little bit of raw meat can sometimes be added in too.

The bottom line is to to prevent your pet from eating foods high in preservatives, additives and fillers. Never leave your pet without a constant supply of fresh, cool water.
