Most of us would be excited to see our best friend in a movie, but Lynnie Bunten has mixed feelings about Beverly Hills Chihuahua.

“I’m looking forward to the movie, but I’m not looking forward to the result,” says Bunten, head of breed rescue for the Chihuahua Club of America.

Sadly, she speaks from experience. Whenever a Chihuahua has been featured in entertainment in the past, it’s been followed by a spike in the number of the dogs given up by people who didn’t realize what they were getting into with these feisty pups.

It’s easy to fall in love with movie stars, especially when the stars are perfectly trained by professional handlers like the glitzy darlings in Disney’s film opening Friday. And Elle, the main character in Legally Blonde, which has been at the Providence Performing Arts Center all week, also has a well-trained Chihuahua on stage.

Remember, the dogs are playing roles. The real-life personalities of various breeds might not be what you’d expect. In the case of Chihuahuas, don’t think laid-back lap dog just because they’re small. Read the breed standard carefully, particularly on temperament.

Chihuahuas are feisty, independent and driven, but because they’re little, people treat them differently. That can mean trouble.

To start with, says Bruce Shirky, president of the Chihuahua club, people tend to be “grabby” with small dogs. Most of us have the sense not to reach out for a strange Rottweiler, but it’s hard to resist the desire to hold something cute and tiny.

Combine that with the fact that Chihuahuas tend to become attached to one individual, meaning they’re not terribly friendly to strangers, and don’t be surprised if your little cutie defends itself vigorously.

Their size combined with their assertiveness can get them into trouble with other dogs, too.

“They will challenge every other dog regardless of size. That can be suicidal,” says Katie Greer, who spent 15 years training Chihuahuas in the sport of agility.

Early socialization and training are critical to keep potential aggression in check. Unfortunately, owners have a tendency to neglect training with small dogs, a big mistake in a breed with the Chihuahua’s temperament.

In addition, Shirky advises, don’t carry your dog in a purse, which just increases the risk that someone will reach for it and get bitten.

“Chihuahuas are famous for being tyrants because people don’t treat them like dogs,” says Greer, who lives in Balch Springs, Texas.

Their drive and intelligence make them great for agility training, which involves a complex race course over different obstacles, but a problem for many owners. In training, “you have to be smarter than the Chihuahua, and you have to convince the Chihuahua that it was the Chihuahua’s idea. This is not a tiny golden retriever.”

Neglect of training may even extend to housebreaking, because a small mess may seem easier to tolerate at first, then fray an owner’s nerves over time. Many Chihuahuas are often given up to rescue for this reason, Bunten says.

If “small” makes you think “good for apartments,” be aware that Chihuahuas are excellent watchdogs but your neighbors may not appreciate the barking and your carpets might not appreciate the terrier-like love of digging.

Chihuahuas aren’t generally recommended for families with small children. Along with their size, a soft spot on the top of the head that they’re born with, like human babies, never closes in some adult dogs.

If you’re up to the challenge of a Chihuahua, rescue is a great place to start. You’ll be dealing with people who know the breed, and the person-

ality of an adult dog is already clear.

If you want a puppy, Shirky advises, buy local so you can make sure it’s being socialized properly from the beginning. The litter should be raised in a high traffic area of the house and have lots of visitors.

And be wary of the description ‘teacup.’ There’s no accepted definition of the term. If you get a particularly small pup, they have more health problems and tend to live very shortened lives.

Smart, funny and loyal, their fans agree, Chihuahuas can be a handful — but that’s what they love about them.

“The world is theirs — they own it — they just allow other people to come into it,” Greer says. “They make me laugh when I see them outthinking me.”
