Chihuahua Health Issues
The average Chihuahua lifespan is 14-16 years; they’re actually one of the longest-living dog breeds.
Along with of their long lifespan, Chihuahuas are generally healthy. But, like all dogs, they are predisposed to certain medical conditions.
Obesity
Weight gain can sometimes be difficult to notice, especially in long-haired Chihuahuas. The gain is usually due to poor diet and lack of exercise. Obesity in dogs can lead to diabetes, joint issues, and heart and respiratory disease.
Luxating Patellas
Patellar luxation is a condition where the kneecap slips out of its normal position, causing discomfort, limping, and arthritis if it becomes a chronic issue. These dogs will be seen occasionally skipping and holding up a back leg while walking.
Often, the patella returns back to the correct position on its own or with a gentle massage of the area. Surgery is recommended in severe cases.
An appropriate diet to avoid weight gain, regular exercise, joint supplements, and physical therapy can be helpful to prevent this condition from worsening.
Periodontal Disease
Periodontal disease, or dental disease, is commonly seen in Chihuahuas because it’s easy for teeth to overcrowd their small mouths. This overcrowding leads to tartar build-up and plaque development. On top of that, many Chihuahuas retain their baby teeth, crowding the mouth even further.
Routine teeth brushing, dental cleanings, and surgical removal of any lingering baby teeth will help keep your Chi’s mouth healthy.
Collapsing Trachea
Collapsing trachea is a condition where the main airway (the trachea) that allows air to enter and exit the lungs begins to collapse on itself. It’s secondary to weakness in the cartilage that normally holds this tube open, and it’s believed that genetics are the main cause.
Coughing (often described as “goose-honking”), wheezing, and respiratory distress are the main clinical signs. It is a chronic and progressive process, which means the signs will worsen with age. Mild cases often require no treatment, while moderate to severe cases require weight management, lessening allergens in the environment, and cough suppressants. If all other remedies fail, surgery might be recommended.
To protect their trachea, pet parents should walk their Chihuahua on a harness instead of clipping a leash to their collar.
