A lot of dog lovers believe there is no such thing as a bad dog, only bad training. Although the right training and socialization can make a difference, it’s a reality that some dog breeds are only an expense due to their frequent illness. Watching your sick pet is one of the most frustrating and painful experiences. While you may want to pamper your pet and give him all the love, health issues could interfere with the life of your pet, not to mention the toll on your wallet. It is estimated that as of 2015, Americans spent over 16 billion on vet care. Medical emergencies could cost you anywhere from $3,000-$4,000. This is why it’s essential to know which breeds are known for health issues when choosing a furry companion. Purebred dogs may seem like an ideal option, however, the selective breeding leads to increased prevalence of inherited diseases. Here are 25 most unhealthy dog breeds.

Chihuahuas are affected by three problems, mainly, an elongated soft palate, luxation of the patella, and hypoglycemia. Unfortunately, most of these problems are hereditary and shouldn’t be bred from. Luxation of the patella refers to the dislocation of the kneecap. The problem is noticeable as the dog ages. If this happens, you need to seek immediate veterinary treatment. Small dogs with elongated palates have difficulty breathing, instead, they snort, wheeze, and sneeze. In hot weather, you’ll realize that these dogs are susceptible to heat stroke. Blood sugars dropping drastically can be fatal in Chihuahuas.
