Tea Cup Chihuahua vs Jack Russell Terrier - Breed Comparison

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.

Chihuahua is a state in the country of Mexico. From this state, the dog breed Chihuahua and the “teacup, or toy” chihuahua take their name. Interestingly the Chihuahua Club of America maintains that “teacup” Chihuahuas do not exist and that the size differential is normal for the breed. Chihuahuas or their ancestors have been around a very long time, sadly the exact origins of the Chihuahua are lost into the pages of history, but archaeological clues such as wheeled dog toys, art, and pottery link the Chihuahua to Mexico and to the Techichi dog. The Techichi dog at the time of the Spanish Conquistadors was sold for food (not unlike we sell beef or chicken) and also as a companion dog to death. Cortez even mentioned the Techichi dog in a letter sent back to Spain, describing them as being raised for food and sold in the marketplace.

When a death occurred a dog was chosen as a companion and cremated with the deceased. It was believed that the dog helped the soul of the decedent reach their eternal destination. The Techichi dog from which the modern-day chihuahua likely descended was very plentiful in the central American area that is now the country of Mexico and raised by the ancient Toltecs and later the Aztec people.

Chihuahuas are little dogs and come in a variety of coats, head shapes and even (within the designation small) sizes. The designation “teacup, toy or pocket” while not an official breed name is a useful descriptor, since they are the littlest of an already small breed and these minute pets, as puppies, may fit into a teacup or a pocket.

Fortunately while no longer a food source, the chihuahua is now sought after as a loyal and lively pet and companion.

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.

Chihuahuas are small. Even the bigger ones are only about six pounds and a “teacup” or “toy” is often three pounds or less. Their bodies are slightly longer than they are tall, but even the tallest are not over nine inches. Chihuahua standing under five inches in height is not uncommon in the “teacup” or smallest of these dogs. They have two different head types and a domed skull. One type of head shape is like a deer while the other is described as an apple-shaped head. The apple-shaped heads are more popular than the deer shaped heads, although sometimes in the “teacup” especially the soft spot fails to close at maturity when growth is complete and the bones should knit, therefore leaving a soft spot in their skull – this is called a molera.

Like different shaped heads chihuahua may have long hair or short-haired coats. The short-haired coats are smooth. The Chihuahua coats may be a large variety of colors ranging from black to white, with red, brown, fawn, cream and chocolate and they may be solid-colored, spotted or sabled. Personal preference is the determining factor on the type of coat a pet Chihuahua has since the breed does not have a preferred color, pattern, hair length or feel. Their muzzle (nose/mouth combination) is short and pointed. Chihuahua have have naturally erect pointed ears and large round eyes. A Chihuahuas tail is relatively long and mostly either curled up and over the back or carried up.

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.

You do need to pay him attention – you can’t just plonk him in your backyard and forget about him. He wants your love and attention and ignoring him can lead to problem behavior such as obsessive barking.

3. Adaptability yes but they are better off in apartments and homes not out in the country where their size makes them targets for predators.

4. Learning ability average ability to learn but Chihuahua can be but stubborn which may impact ability and willingness to learn.

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.

Chihuahuas live on average fourteen to eighteen years. There are some issues that may cause concern or lower life expectancy.]

• Hypoglycemia (low blood sugar) is something to watch for. Low blood sugar can cause death in just a few hours but when caught is very easily treated. Some of the symptoms are being uncoordinated when walking, acting sleepy or lethargic, unfocused sight, fainting, having a seizure or having spasms in the muscles of the neck. First aid can right this condition with a sweet supplement like corn syrup, or honey. This is more common in puppies, but the teacup chihuahuas are susceptible.

• Hydrocephalus (water on the brain) can affect many toy dog breeds. The puppy or dog will appear to have an oversized head, and be slow (display lethargy) and grow slower than its littermates.

• Pulmonic stenosis (a heart condition) occurs when the right ventricle is impeded. Teacup Chihuahuas are also susceptible to heart murmurs.

• Collapsed trachea this occurs when the cartilaginous rings in a Chihuahua do not form completely or weaken. This can be hereditary or an acquired condition and occurs in other small breeds of dog.

• Molera – where after finishing growth a soft spot remains in the skull and the bones do not knit. As a puppy, the owner must remain vigilant about head injuries.

• Obesity (overweight). Most of the time this is a result of the Teacup Chihuahua being overfed. Obesity can contribute to a shortened lifespan and chronic bronchitis.

• Cold susceptibility. Cold weather can cause Teacup Chihuahuas to shiver or tremble when exposed and during cold temperatures, the dogs may need to wear a sweater and boots outside and cuddle with their owners under blankets or bask in the sun to stay warm.

• Infected or injured eyes. Due to the prominent eyes, exposure to irritants such as dust, allergens, or dry air can cause the dog to develop this beginning with watering eyes.

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.

1. Feeding the Puppies. Puppies should be fed four times a day. Underfeeding can cause the issues of low blood sugar and overfeeding can result in obesity increasing the risk of other health complications.

2. Feeding the Adult. Adult teacups are also vulnerable to hypoglycemia and obesity. Of course, the low blood sugar will be much more acute than obesity and need prompt care if it occurs. Adult teacups should be fed twice a day.

3. Points for Good Health. The chihuahua generally exhibits more vigor and endurance than pet owners expect from such a small breed of dog.

4. Games and Exercise for Teacup Chihuahua. Go ahead and run and play but remember even with the unexpected stamina and endurance this is a very small dog, small legs, using discernment, judgment, and restraint so the games and exercise is fun and builds health and is a special bonding time, without jeopardizing the sugar levels or causing exhaustion or misery.
