Chihuahuas are indeed prone to brachycephalic health issues. This is largely due to their short, flat face and narrow airways, which can lead to breathing difficulties.
Their skull shape is one of the main culprits, as it can cause their airways to become pinched and narrow. This can lead to a range of problems, including respiratory distress and even collapse.
Chihuahuas are also more likely to experience heat intolerance, as their short noses make it harder for them to cool themselves down. This can be a major concern in warm weather.
In fact, studies have shown that Chihuahuas are more prone to brachycephalic syndrome than other breeds, with up to 90% of the breed affected.

Brachycephalic Syndrome
Brachycephalic Syndrome is a real concern for Chihuahua owners. The breed's flat face can cause breathing difficulties due to the shortening of the nasal passages and the elongation of the soft palate.
Chihuahuas are prone to respiratory problems, which can be exacerbated by their brachycephalic skull structure. This can lead to noisy breathing, panting, and even collapse.
Brachycephalic Syndrome can be caused by a combination of genetic and environmental factors. In Chihuahuas, the condition is often inherited from their parents.
Dogs with Brachycephalic Syndrome may exhibit symptoms such as snoring, wheezing, and difficulty breathing during exercise or in hot weather. These symptoms can be distressing for both the dog and the owner.
Chihuahuas are more susceptible to Brachycephalic Syndrome due to their unique skull structure.

Understanding Boas
BOAS is a serious condition that can impact every dog differently. It's caused by a dog's short-nosed and flat facial shape, which can lead to difficulty breathing, noisy breathing, and increased breathing effort.
If you think your dog might have BOAS, contact your vet right away. They'll assess your dog for signs of BOAS and may refer them to a specialist if needed.
Narrow nostrils, a long soft palate, and a narrow windpipe are specific features that might be encountered in a dog with BOAS. However, not all brachycephalic dogs will have these features.
Difficulty breathing can lead to exercise intolerance and an increased risk of heatstroke in dogs with BOAS. This is a serious concern that requires veterinary attention.
Gastrointestinal problems like regurgitation can also be a symptom of BOAS. It's essential to monitor your dog's health closely and seek veterinary care if you notice any of these signs.

Obtaining a Brachycephalic Dog
You can't guarantee a brachycephalic dog won't have health problems, but you can increase the chances by buying from a reputable breeder.
Research the health testing required for the breed you're interested in.
Find out if the breeder is part of the Kennel Club Assured Breeders Scheme or the Scottish Society for the Prevention of Cruelty to Animals (SPCA) Assured Breeders Scheme.
Ask for copies of the puppy's mother and father's health certificates.
Consider using the Kennel Club's Assured Breeders Scheme Puppy Contract to protect yourself and the seller.
Setting up a pre-purchase consultation with your vet or vet nurse can also be helpful.
