Is Boston Terrier a Chihuahua? 

A Boston Terrier is not a Chihuahua. While they share some facial features and personality traits, Boston Terriers and Chihuahuas are not the same due to their differences in parent genes, health issues, and living needs. 

Similarities Between the Boston Terrier and Chihuahua 

You may get confused between the two breeds at first glance. However, a Boston Terrier is not a Chihuahua, even if they both have these characteristics and aspects.

  • Temperament: These intelligent dogs are curious, causing them to please the people around them through their alertness and responsiveness. They are also affectionate and sweet, resulting in them enjoying the attention. However, they also tend to get jealous quickly and don’t like being alone. 
  • Barking: Chihuahuas and Boston Terriers are above average barkers, particularly when provoked or threatened. 
  • Friendliness with Other Pets: Both the Boston Terrier and Chihuahua are great with other pets, especially dogs and cats. Be careful about Chihuahuas playing with larger dogs, as a larger, hyper dog may hurt your Chihuahua. 
  • Owner Experience: Both breeds are suitable for new or inexperienced owners.
  • Sensitivity Level: Chihuahuas and Terriers don’t like noisy households and frequent guest visits.
  • Hypoallergenic: No dog is 100% hypoallergenic, yet these two breeds are among the less hypoallergenic ones, which means they shed very little or not at all. Unlike common hypoallergenic breeds, they don’t release allergy-causing agents from their fur to the air. 
  • Grooming Needs: Since they have short coats, Boston Terriers and Chihuahuas rarely need to have their fur trimmed, shaved, or cut. 
  • Energy Level: Chihuahuas and Boston Terriers have high energy levels, making them ideal for people with active lifestyles. Combining this energy level with their cleverness and vigilance, it will be fairly easy for you to train them. 
  • Adaptability: Boston Terriers and Chihuahuas adapt exceptionally well to lifestyle changes and most living environments.

Chibo: The Boston Terrier and Chihuahua Mix 

The only time I can say that a Boston Terrier is a Chihuahua is when I’m talking about the Chibo, which is the offspring of the two breeds. Also known as Bochi or Bohuahua, this small, designer dog is a bold and agile creature. 

Chibo usually comes with a combined temperament, being friendly, outgoing, active, and loyal. Since it takes some genes from a Boston Terrier, a Chibo has a larger size than a typical Chihuahua, weighing around 10 to 15 pounds and standing at seven to 17 inches. 

Moreover, a Chibo has a muscular body with a squared head and muzzle, along with bat-like ears similar to a Chihuahua. Like a Terrier, a Chibo tends to have a short, straight coat, as well as a corkscrew tail.

Much like its parents, Chibo has low maintenance grooming needs. However, the hybrid doesn’t fare well in extreme cold and heat. Because of its genes, Chibo can normally live up to 15 years.
