Your Jack Chi is a hybrid canine resulting from the breeding of the Jack Russell Terrier and the Chihuahua, and is a fairly new hybrid on the scene. A renewed interest in crossbreeding purebred dogs has been resurrected over the past two to three decades. It is believed that this hybrid was developed during this period, estimated to have begun in the 1980s or 1990s. A small to medium-sized canine who appears to have been bred for companionship purposes, they have been described as being sweet, affectionate, friendly, playful, alert and energetic. They are considered to be low maintenance in the grooming and care category, requiring only weekly brushing, unless the Chihuahua breed parent was of the long-haired variety. In this case, if the long-haired Chihuahua breed parent has a dominant role in the coat of your pet, and the coat is longer, brushing may be required several times a week. Bathing is generally done only as needed to keep the coat clean and sweet smelling.

Jack Chi Breed History

Your Jack Chi hybrid family member is the product of the breeding of a Chihuahua and a Jack Russell Terrier for the purpose of family and individual companionship.  This is a fairly new hybrid and, as such, there is little history about them beyond the fact that they were developed in the United States.  One can only assume that the approximate date of origin falls into the past two to three decades, a time of regeneration of crossing and mixing a variety of purebreds to create these “designer” or hybrid canine breeds.  While there is little historical information about the Jack Chi, there is plenty of information available on the parent breeds, the Chihuahua and the Jack Russell Terrier.  The Chihuahua breed hails from Mexico and can be traced back to the 9th century where images of a dog resembling the Chihuahua have been found in artwork, written works and other artifacts.  Though the history of the origination of the Chihuahua remains shrouded in folklore, they are believed to have been developed in ancient Mexico as a dwarf pet canine. This parent breed made their appearance in the United States in about 1850 and has been firmly implanted ever since.  The Jack Russell Terrier originated in the United Kingdom in the early 1800s for hunting and tracking purposes.  The small size and compact build of the Jack Russell made them perfect as they were large enough to keep up with the foxhounds but small enough to “go to ground” and rout the foxes from their dens.  Today, while their noses remain ever vigilant for those unusual and interesting scents, they are primarily utilized as family pets and companion dogs.

Jack Chi Breed Appearance

Your Jack Chi can take on the appearance of either or both of the parent breeds, the Chihuahua and the Jack Russell Terrier.  The coat will likely be short and dense and the colors of the coat can be black, white, brown, chocolate, cream, golden, fawn, black and brown, black and white, black and tan, brown and white, dark brown, light brown and tricolor.  They are described as being a small to medium sized dog, being a maximum of 15 inches tall and weighing between 8 and 18 pounds.  They have a dense coat, short neck, elongated but muscular body and large eyes on a triangular head. The ear set can be either erect like the Chihuahua parent or folded or curled over like the Jack Russell parent.  The snout, body build, and coloring generally show the contributions from the Jack Russell parent while the coat and the length of the legs are more like the Chihuahua side.  It is quite possible that your Jack Chi could actually be under 10 inches at the shoulder!  The muzzle could also take on the thinner size from the Chihuahua side.  The facial expression will be alert and intelligent with large dark eyes and a black nose. The hindquarters will be strong and muscular to provide the strong, springy gait and jumping ability from the Jack Russell side with feet that can be round and thickly padded or small and dainty with good padding, the padding likely being pink or multicolored.  Your cute pup will have a tail that resembles the Chihuahua side, being long and a little fluffy.

Jack Chi Breed Maintenance

The Jack Chi is considered a moderate shedder.  Brushing once or twice a week should help to remove loose, dead hair and debris from their coat.  Your pup needs bathing only as necessary.  Your furry friend will need to have their ears checked and cleaned regularly to avoid infection caused by dirt and bacteria. Keeping up with dental examinations and teeth cleaning will help to reduce the potential for periodontal disease development, which is common among canines.  Eye examinations should be done to assess and monitor any of the variety of eye problems, both internal as well as external, which are known to afflict the parent breeds. Check your dog's nails for length twice a month, trimming as needed.

Jack Chi Temperament

Your Jack Chi will definitely be a delight to have underfoot!  Full of energy and love but not easily trainable, this little guy naturally tries to be the leader of the pack.  You will need to be very patient and firm as you train, using positive encouragement and reinforcement to establish who’s in charge.  Don’t be afraid to request professional help if training seems overwhelming for you and your daily life schedule.  Your Jack Chi will get along great with children and other pets, though smaller ones could be looked upon as prey (from the Jack Russell side, no doubt) and some aggression and stalking might be experienced.  Early socialization should reduce any aggressiveness toward small children and pets. Generally friendly with everyone, strangers may produce some wariness or caution.  Early socialization should help to modify this as well.  Be prepared to provide lots of exercise and play for this energetic, frisky pup.  Both breed parents contribute the potential for large amounts of energy which will need to released on a daily basis.  Not following through with appropriate exercise periods and activities could lead to some inappropriate and unappreciated destructive behavior – remember that your dog is at heart.  

Jack Chi Activity Requirements

Your Jack Chi hybrid is an energetic bundle of love and playfulness.  This energy will need to be spent daily to keep them healthy and happy, the need to avoid boredom being great.  Taking your companion for long walks a couple of times a day will help achieve this. Keep your dog on a leash when outside as their tracking and hunting nose never stops seeking scents.  Also, because your Jack Chi is so intelligent, hide and seek games will keep your furry family member from becoming bored and avoid the development of annoying chewing, digging and destructive behaviors. Because of their small size, they are perfectly suited for apartment or condo living, but remember that exercise needs must be met on a daily basis.  It is important to note that, because of the traits inherited from the Jack Russell side, your dog will need to be safely monitored in the yard with a high-walled fence that will be difficult for them to jump.  Care must also be taken to prevent digging for an escape route.

He is a puppy from our male jack russell, Astro. Dad did not like him at all, very jealous. Ruger has grown up to be a bully. He does not share any new toys, and likes to pick fights. They are the best entertainment, protectors,friends you could ever ask for.

My Jackchi is such a little love bug. She loves everyone,and is always happy to greet them; hi man and animal alike. I had 2 ferrets with her at one point and she loved playing with them. She also loves cats,she even pretends my friend's kitten is her baby when she is around her. She loves riding in the car, going for visits, just being with me as much as possible. She is crate trained but does not need to be. Not a barker either. She is very smart and also very good motivated. She knows the following tricks (and enjoys learning new ones): sit,stay,come,no,leave it,enough, up, down, lay down, roll over, sit pretty, salute, paw, other paw, give, other five, ten, and dance.again did I say how much she loves to learn and how incredibly smart and eager to please she is. SShe is a great dog all around.She does shed a decent amount as she is semi long haired,also she wants to give you kisses all of the time. I have not had any health issues with her except for her reverse sneezes that scare her when they happen.

Never saw myself with a small dog but when we met him and I bonded and I couldn't be happier. He is the best. I think he saved my life more than once but for sure one time so I am debted to him for the life he saved. Listens very well, can't catch good but it's ok, he's lightning fast, smart, not a yapper, friendly with all and just a joy to be around. I'm gonna say it again my dog Rhouzer is the BEST GOOD BOY IN THE WORLD. I got lucky with finding him.

She is my first small dog, but she's great. Easy to train, not expensive to feed. She goes to work 5 days a week as the office dog. Good with people and other dogs, quite, just doesn't like cats much. So pretty much perfect.

Jamu is a very affectionate dog and he’s super friendly. He loves new toys and new people. He has a tendency to want to explore any new person that comes around him. He is an avid sniffer and will spend hours sniffing the ground for new things to get into. He has to be supervised because he will get into anything he can and start chewing. He particularly loves to steal our socks and T-shirts. Toys don’t last more than a week before they are destroyed. He loves to play with other dogs too. We gotta be careful with him because he will eat anything and I mean anything, that can fit in his mouth. Potty training has been a long hard battle, but we finally got it done. He’s pretty hard to train. He also tends to whine a lot. He likes to cuddle and often takes little naps. He hates car rides and it’s probably because he gets so car sick and throws up everytime. But we went to the vet and we have medicine for his car rides now. Overall he’s a very busy dog personality wise and he’s super loving.

My jackchi is fun and loving, he is full of energy. He constantly wants to play and is very active. But when he is more calm he loves cuddles. He is very sociable and loves meeting new dogs and people. He is definitely a chewer as he would chew anything he finds so you need to be very careful of what you leave in the house because he will go for anything. I have bought him so many toys and he destroys them in like two days so I try to buy now toys that are very strong so I don't spend lots of money in new toys. It is very hard to train him and in the park if I leave him out of the lead he runs away and even if I call him he would not come back because he is busy playing with other dogs so I have to run to get him. I am very busy and I find difficult to find time for what this type of dogs demands. I would recommend it to someone with lots of patience and time.
