The Rat-Cha is a crossbreed between the purebred American Rat Terrier and Chihuahua.  This designer dog has high energy and is very loving toward their family.  The Rat-Cha, also called the Rat-Chi, is frisky and can be overprotective of their people.  Owners can prevent aggressive or undesirable protective traits by early socialization with people, places, and other dogs.  This cute and perky Rat Terrier Chihuahua mix tends to bond with a single person in the family and will spend much of their time on that person's lap.

Rat-Cha Breed History

The Rat-Cha is a popular designer breed due to the high popularity of both parent breeds.  Despite the pup's popularity, detailed accounts of their breeding programs and history are not available.  This is most likely due to the recent hybridization of both parent breeds and the number of variations that can be present in the Rat Terrier Chihuahua mix offspring.  Owners who wish to understand the histories and potential traits of their Rat Terrier Chihuahua mix can review those of both parents for insight. The American Rat Terrier is an American breed long in the making.  The breeding program included several other well-established breeds, such as the Manchester Terrier, Bull Terrier, Old English White Terrier, and the Fox Terrier.  The purpose of the breed programs was to produce a small Terrier type that was a tenacious ratting dog, and that could get in tight places.  Despite their late recognition by the American Kennel Club in 2013, the American Rat Terrier has been long bred in the United States.  A Rat Terrier appeared alongside Shirley Temple in The Little Colonel and was the Terrier of choice of President Theodore Roosevelt, who wanted a rat dog to handle the White House rat problem.  The Rat Terrier varied in the United States depending on the region they were from as well.  In the south, the Rat Terrier was crossbred with the Beagle to produce a pack-minded ratting dog while the Greyhound and Whippet breeds were used in the midwest to give the Rat Terrier fleet abilities against the fast jackrabbits. The Chihuahua is also a dog of the Americas but from Mexico.  Accounts of the Chihuahua, known then as Techichi, reach back as far as the 9th Century in the Mesoamerican region where the little dogs were bred as both vermin hunters and companions.  The Techichi was so well loved that they were often buried alongside their masters at death.  The Techichi faded into obscurity during the Spanish invasion of the Aztec State, but the small, resilient dog maintained themselves in the region and were rediscovered living in the Mexican state of Chihuahua during the mid-1800s, where the breed gained their new name.  Shortly after their rediscovery, the Chihuahua made their way north to the United States by the late 1800s and the American Kennel Club recognized the breed in 1904.  Interest in the Chihuahua grew fast, and by the 1960s, the Chihuahua was considered one of the most popular dogs in the country.  Today, the Chihuahua still enjoys a high popularity ranking in the American Kennel Club.      

Rat-Cha Breed Appearance

The Rat-Cha may vary widely in appearance not because the parents are so widely different, but because there is variation in the parent breeds standards.  However, this hybrid is sure to be small with a soft, sleek coat.  Some Rat-Chas have longer hair, depending on their parentage as both parent breeds may exhibit longer hair.  Their head is small and round with large, triangle-tipped ears that stand up.  The eyes are dark, round, and prominent but do not bulge out as much as the Chihuahua parent's eyes.  Both parent breeds suffer from dental issues, and this tiny-mouthed pup may have missing teeth or poor dentition, such as an underbite, both of which are not desirable traits.  The body is compact and long, with thin legs and a wiry short to medium-length tail.

Rat-Cha Breed Maintenance

The Rat-Cha is an easy dog to maintain and has minimal grooming needs.  They are moderate shedding dogs, and weekly brushing will help remove any excess loose or dead hair.  They are not a hypoallergenic dog, but weekly grooming will help keep the allergens down.  The Rat-Cha is not known to have a doggy odor so any fouls smells may point to a health concern, such as ear infection or dental issues.  This little dynamo is prone to developing dental problems, many of which may be prevented by keeping their teeth clean.  Owners can help their dogs maintain healthy mouths by brushing their teeth frequently and providing them with hard, rubberized chew toys.

Rat-Cha Temperament

The Rat-Cha is an affectionate companion that typically bonds with one person within the family.  They require early socialization to reduce aggressiveness toward strangers and are not well suited for young children.  They have high energy but prefer activities on their own terms rather than being forced to play.  Often, this snuggler is perfectly content on their owner's lap.  They do not have a pack mentality and prefer to be single dogs living under one roof.  However, with socialization, they can learn to live in harmony with other dogs.  The prey-mind may make living with cats more difficult, but socialization will also help with this.  House training the Rat Terrier Chihuahua mix is relatively easy, considering how small the breed is.  This is attributed to this pup's high intelligence and desire to please their master.

Rat-Cha Activity Requirements

The Rat-Cha is an active hybrid with high energy.  However, activities are often done in short bursts, and this mini companion can get most of their daily exercise in the home.  They are highly adaptable to small space living, but a small backyard where they can run and jump is ideal for this designer dog.  They should not be left alone outside and do not tolerate being alone for long.  They may develop negative behaviors, such as chewing or digging if they become bored or lonely.  The Rat Terrier Chihuahua mix does not do well in cold environments and prefers warmer ones.  However, this breed can live just about anywhere considering they will spend most of their time in a climate controlled home.

Tut is such a wonderful dog with one of the most unique and fun personalities I’ve ever seen be it dog or person. He loves cuddling and will follow me around the apartment whenever I get up. He is always full of energy and will typically grab his favorite toy (he only likes one toy) and will run around in circles for about ten minutes and then lay down on my lap. He is so loving and gentle, he treats his toys with care, he doesn’t rip them apart which seemed strange at first because of the rat terrier in him, but it is so adorable to watch.

Soi is White, Black and Fawn Ratcha. I adopted her 2 years ago from a local animal shelter. She took to our family very quickly. She is very attached to me and follows me everywhere, I don’t even need a leash when I walk her. She just makes sure she can see me. She doesn’t like large dogs much but she is very friendly to cats and small dogs. She sleeps with me every night and she eats very well. She is my best friend I don’t know what my life would be like without her.

Barbie is a very lovely dog and enjoys playing a variety of games. She can be a brat at times, for example she acts rebellious when she is loose outside and doesn't listen when called.She often barks at people and hates bigger dogs but is friendly towards small dogs. I like to joke that she should've been named Raquel instead of Barbie. Though she has her chihuahua side of her that makes her act as if she cant be devoured by larger dogs, deep down she is just a fragile Barbie doll. She is a picky eater though that is probably my fault because i spoil her with treats. She's actually the cutest thing, especially when she wants attention; she tugs at your hand and puts her head under it. Overall, Barbie is a good girl and props to her for sticking around with an annoying owner like me.

I got Drogo about a week ago from the Humane Society. He adjusted quickly to his new home. He is more attached to me, but he also cuddles with my boyfriend and follows him around. He has a lot of energy and chews through toys easily. He's 22 lbs according to the vet, and stands maybe 18 inches tall. He likes to jump on people and has no problem adjusting to new people. Other dogs are questionable. He is definitely protective of me. He has a fawn coat with paler spots at his shoulder blades and bend of his tail. He's super affectionate and the best thing I've ever done. I wouldn't trade him for the world.

My fawn and white Rat-Cha is loving to all the members, including my 21 month old son, and patient. He is super intelligent and easy to learn tricks with. He is alert and protective of us as well. I love his confidence and cautiousness when he meets new people and dogs. He is also very fun to nap and cuddle with. Yet, he respects personal space and likes time to himself as well. He doesn’t shed much and what he does shed is easy and quick to pick off. Also, he doesn’t have that pungent dog dander odor. He is perfect for our current lifestyle and our apartment. A very go-with-the-flow kind of attitude if your provide enough stimulation, which isn’t very much. He is easy and fun to play with. I love him very very much!

He is a great dog that is very independent. He was a rescue and had trust issues. He quickly bonded to me, and when I take him home to my mother. He spends most of his time sitting on my lap, but then will sporadically play for 5 minutes. He is still pretty sketchy when he is around young/loud children. He is scared of new people, but rarely barks.

Jess is a sweet baby who we found in the streets a few months ago. He was very friendly when we found him, but now that he has gotten comfortable with us, he is a little more protective and aggressive to people who come into our home. Most of the time he just wants to sleep in a comfy spot, but he also loves to play and go on walks. We make sure he gets 4 walks a day and lots of play time. I also give him calming supplements and hip+joint supplements since his breed is prone to these sorts of problems. We have only had him a few months, but his vet says he is healthy and we are absolutely in love with him!!!

GMan is possessive and very protective of me to the point of aggression. He growls at men especially who try to get near me and he doesn’t like other dogs or animals at all!!! He only likes to be with me and my male companion and a few of his roommates who feed him hot dogs. GMan has a sensitive digestive system and can’t eat anything in the way of human food or he gags, chokes, and vomits. He loves to eat however, and gobbles his own food three or four times a day. I feed him small portions of fresh pet or some soft refrigerated chicken meat which has spinach and fruit as well. GMan loves sleeping under his yellow green blanket and likes to frolic in piles of leaves and on fresh green grass. He is a loving dog and good companion animal for me and my male friend, but even gets bitey and growls at us occasionally. He was brought up from Mexico on a truck in a cage in his own vomit and feces and came to me with kennel cough which turned to pneumonia and had to be hand fed and on antibiotics and was a victim of the Oregon Humane Society and the evil drug culture in Mexico and criminals who steal dogs and transport them from a scandalous crime ridden system in a Mexico and in the US all over which takes stolen dogs and sells them as “Rescues” to unsuspecting and vulnerable America elders and poor people who think they are helping rescue dogs and saving themselves some money. Also, there is a huge problem in overbreeding these RAT CHA dogs and making too many of them for greedy people trying to profit financially for their own benefit. UGLY UGLY UGLY The RAT CHA is a dog that should not be overbred. They are aggressive and not good with children and nip and bite people. I am terrified personally!!

She is one of the dorkiest dogs I have ever met. She is very particular about which people she likes. She is very protective of her family and will act like a guard dog. She is very curious and loves food. When she was a puppy she was very easy to train and is very good about being potty trained. Loves to sleep at times and then will get bursts of energy. Definitely a loyal dog to those she loves. Has suffered from some seizures in the past with unknown causes does not have them frequently though. Also sneezes a lot which actually gives her character. For her age she jumps around and still has a lot of energy.

His favorite thing is to lay and sleep under blankets. Loves to cuddle anybody. He is very intelligent and easy to train. Very, very protective of everybody in the family! Actually barks and "attacks" if there is play hitting going on or wrestling. Biggest issue is separation anxiety; If family is leaving and he knows he will be all alone, he will whine and bark. However, this makes him very excited and happy when somebody comes in. Does amazing with new people. Doesn't get along with other dog, and acts okay with cats. No dental issues or health issues (yet), and very low maintenance. Does play from time to time and have funny bursts of energy. Not too bad in the bath and just fine on walks. Probably the best dog we have had!!

He's a great friendly dog who gets along with every dog he comes into contact with. His high energy can be annoying at times, but it's just part of his personality. If you let him play hard and run around till he tires himself out, then he'll be a good lapdog like this site says.
