Chug: What to Know Before Adopting a Chihuahua–Pug mix

The Chihuahua–Pug mix, often called a Chug, is a small dog with a big personality and plenty of allure. This mix became more popular in the early 2000s, and it’s easy to see why — Chugs can bring together playfulness, affection, and a surprising amount of confidence in a compact package.

They vary in size, energy level, and temperament, depending on which parent breed they inherit more from and their individual personality. Some Chugs lean more energetic and alert, while others are more laid-back and people-focused, which means there’s a wide range of Chugs who can fit different homes and lifestyles. Here’s what you can expect when adopting a Chug.

TL;DR: Chihuahua mixes, such as the Chug, combine traits from Chihuahuas and Pugs. They are often affectionate, smart, small dogs who love their people.

Why we love Chugs

Like any mix, their physical and personality traits are somewhat unpredictable, but most Chug dogs are affectionate, loyal, and playful, making them great pets for singles, families, or seniors. They adapt well to smaller living spaces, and with proper training and care, they can be wonderful companions. Here are a few reasons why Chugs are a great match.

• Chugs are small and compact: Chug dogs can weigh between 10 and 20 pounds and might stand six to 12 inches tall at the shoulder. Still, their size varies depending on whether they take more after the stockier Pug or the diminutive Chihuahua, and any other breeds in their mix.

• Chugs don’t need a lot of grooming: Sure, Chugs will need some grooming, but it’s a relatively easy job. Regular brushing, bathing, dental, and ear cleanings are necessary to keep them clean and healthy. 

• Chugs are a colorful bunch: Chug dogs come in a rainbow of colors, including fawn, black, brown, cream, white, brindle, sable, and black-and-tan. Chugs may be solid, bicolor, or tricolor, and some Chugs have black masks.

• Chugs are pretty smart: Although Chihuahuas and Pugs are not among the “smartest breeds,” they are still fairly intelligent. And they respond really well to positive reinforcement, such as treats, praise, and playtime.

• Chugs are friendly pups: Both Chihuahuas and Pugs are known for being highly affectionate and people-oriented, which usually translates to a friendly demeanor in Chugs. They are typically affectionate and form strong bonds with their pet parents, though temperament can vary in individual dogs.

• Chugs are not high-energy: While many Chugs have a moderate energy level, some are better described as couch potatoes. These pups will likely do well with short bursts of play, walks, and a bit of exercise.

Things to consider before you adopt a Chug

Chugs are cheerful and friendly dogs who do well with many types of adopters. However, there are a few factors to consider before choosing to adopt one.

Chugs are shedders.

This mix has a lot going for it, but being low-shedding is not one of their traits. Long-haired Chugs might shed less than short-haired Chugs, but either way, they are considered moderate shedders. Frequent brushing can help manage hair around the house.

Chugs need supervision with children.

The Chug’s small size means they require gentle handling, especially with young children. Chugs are often affectionate and playful, traits that can make them wonderful companions for children, but this is largely dependent on the individual dog’s temperament and whether they were properly socialized to kids from a young age. 

As with any breed, it is recommended that your child is always supervised when interacting with your dog to keep both the child and dog safe. Teaching children how to properly approach and handle dogs is crucial to ensure positive experiences for both the dog and the child, as is teaching dogs how to interact gently with children.

Chug need slow introductions to other pets.

Chug dogs can get along well with other pets, including both cats and dogs, especially if they have had plenty of early socialization experience and have a more relaxed personality. But remember, individual temperaments will vary. 

Pugs are typically social, friendly dogs who enjoy the company of others. ​​But Chihuahuas, on the other hand, can sometimes be a bit more assertive, especially around those they don’t know. Supervision and gradual introductions help ensure a positive relationship between them and other pets.

Chugs are a bit stubborn.

Chug dogs are not impossible to train, but it might feel that way sometimes. These small dogs might need extra patience due to their independent and sometimes stubborn nature, but the good news is that, with consistent training, positive reinforcement, and short, fun sessions, a Chug can become a well-behaved companion.

Chugs do need dental care and grooming.

Proper dental care and nail trimming are important aspects of their grooming routine. Chugs with a short coat don’t require haircuts, but they benefit from weekly brushing to remove loose hair and minimize shedding. Some Chugs might have longer coats (inherited from long-haired Chihuahuas), and these pups might need more frequent brushing to prevent tangles.

9 Most Common Chihuahua Health Problems

These cute little pups can develop not-so-cute problems. Here’s how to prevent and detect their common health issues.

Chug health considerations

Chug dogs are generally healthy, with a life expectancy of 10 to 15 years, but they can be prone to certain health issues, as both the Chihuahua and the Pug are prone to genetic conditions that may be passed down. Schedule annual visits with your vet to monitor their health and stay updated. Common health concerns for Chugs include:

• Brachycephalic syndrome: Because Pugs have flat faces, Chugs might inherit this trait, which can lead to brachycephalic obstructive airway syndrome (BOAS). BOAS can cause breathing problems and difficulty breathing in extreme heat. Chugs with brachycephalic features might snore or wheeze and will likely need to avoid activity in high heat.

• Patellar luxation: Both Chihuahuas and Pugs can be prone to patellar luxation (dislocating kneecap), which can also affect Chugs. 

• Obesity: Chugs, like both parent breeds, can be prone to obesity if not properly exercised or if overfed. It’s important to keep them at a healthy weight to avoid joint strain and prevent health problems associated with obesity.

• Eye problems: Pugs are prone to eye issues such as dry eye, corneal ulcers, and glaucoma. Chugs can inherit some of these problems, especially if they have more of the Pug’s face shape. 

• Heart issues: Chihuahuas can sometimes have heart murmurs or other heart-related conditions, so it’s important to keep an eye on your Chug’s heart health, especially as they age.

• Dental issues: Chihuahuas are known to have dental problems due to their small size and compact mouths, so Chugs might be prone to tooth decay and gum disease. Regular dental care, such as brushing their teeth or providing dental chews, is important for maintaining their oral health.

Ready to adopt?

There are many Chug dogs waiting for someone special to adopt them. Many breed-specific rescue organizations for Chihuahuas and Pugs have Chug mixes available for adoption. Chugs or Chihuahua/Pug mixes also end up in animal shelters and rescues. A great place to start looking for a Chug is on Adopt a Pet.

Commonly asked questions

How much do Chug dogs cost?

The price for a Chug puppy from a breeder typically ranges from $300 to $1,500. Adopting a Chug from a shelter or rescue group is much more affordable. Adoption fees usually range from $50 to $300. The adoption fee often includes vaccinations, spaying or neutering, and sometimes even microchipping, which adds value compared to purchasing from a breeder.

Do Chug dogs bark a lot?

Yes, Chug dogs can bark a lot. Chihuahuas are known for barking a lot, so Chugs are often fairly vocal too. They tend to bark to alert their pet parents, out of excitement, or if they are anxious or bored, which means that their barking can be managed with proper training and mental stimulation. 

Can Chugs be left alone?

Yes, Chugs can be left alone for short periods, but they love you so much that they prefer you don’t. Chugs can become lonely or anxious if left by themselves for too long. Ideally, Chugs should not be left alone for more than four to six hours at a time. If you work full-time or are often away, you might want to consider a dog walker or pet sitter to ensure your Chug gets the companionship and care they need during the day.

Do Chugs pick one person?

Yes, Chugs can sometimes form a particularly strong bond with one person. 

Are Chug dogs hypoallergenic?

No, Chug dogs are not hypoallergenic and they produce allergens like any other dog.
