Small Dog Breed Health Concerns

Tiny dogs may face peculiar health problems due to their small size. Here are some common issues you might see in popular toy breeds. 

Orthopedic injuries 

Despite their agility, small dogs are prone to orthopedic problems due to their lighter and more fragile bone structure compared to larger breeds. One of the most common orthopedic issues in small breeds is patellar luxation. This is where their kneecap slips out of place, causing pain and sometimes difficulty walking.

Breeds like Dachshunds and Shih Tzus are particularly prone to IVDD, a condition where the discs between the spine’s vertebrae herniate or burst. This can cause severe pain and neurological issues, including paralysis. The long, low bodies of these breeds contribute to their risk.

Tracheal Collapse

Many small dogs have a tendency for tracheal collapse, where their windpipe weakens and collapses, making breathing difficult. In small breeds, these cartilage rings can be weaker and more prone to collapsing.

In addition to this anatomical cause, many toy dog breeds are genetically predisposed to tracheal collapse. Breeds like the Chihuahua, Pomeranian, Toy Poodle, and Yorkshire Terrier are particularly prone to this condition. Keeping your dog at a healthy weight and using a harness instead of a collar can reduce stress on their windpipe.

Dental issues 

Tiny dogs have tiny mouths. However, these tiny mouths often have packed teeth, leading to overcrowding and dental problems. These problems include plaque buildup, gum disease, and tooth loss. Regular dental care and occasional professional cleanings can prevent this.

Brachycephalic Airway Syndrome

Breeds with short noses, like Pugs and French Bulldogs, can suffer from brachycephalic airway syndrome. This condition causes breathing difficulties due to their narrowed airways, making them great watchdogs, as even minimal bark can indicate distress. Such dogs should always have their breathing monitored, especially in hot weather, and should avoid strenuous exercise.

Obesity 

Because toy dogs have smaller stomachs and lower energy requirements, even a few extra treats can significantly affect their weight. Pocket-sized dogs can gain weight quickly, and even a few extra pounds can strain their tiny bodies. Obesity can lead to a host of issues, including diabetes, joint problems, and heart disease.

According to the American Veterinary Medical Association data from Banfield Pet Hospital revealed that overweight dogs, often exhibiting huge personalities in small bodies, typically live up to 2.5 years less than dogs maintaining a healthy body weight. Feeding your dog a balanced diet and ensuring regular exercise is key to keeping them fit.

Mitral valve disease 

According to Cummings School of Veterinary Medicine, degenerative mitral valve disease (MVD) is a common heart condition in small dog breeds. The structure of the mitral valve in small breeds can be more prone to degeneration over time. The mitral valve controls blood flow between the left atrium and the left ventricle of the heart, and in toy dogs, this valve can deteriorate faster due to genetic factors.

Regular vet visits, a healthy diet, and proper care can go a long way in preventing and managing mitral valve disease.

Potential benefits of owning a small dog breed 

Owning smaller dogs has tons of perks! They’re easy to handle and perfect for apartment living since they don’t need a lot of space. Plus, they’re budget-friendly because they eat less, and their supplies are often cheaper.

Also, traveling with a small dog is easy. You can put your dog in a small carrier, and they are usually allowed on planes and trains. They also tend to live longer, giving you many years of friendship.

Little dogs are great cuddle buddies and adapt well to different lifestyles. They’re safer for families with kids or seniors and can even offer emotional support and stress relief. They’re lovable, low-maintenance, and perfect for almost any living situation.
