Yorkshire Terriers, with their silky coats and spunky personalities, are undeniably captivating companions. However, like all breeds, Yorkies are predisposed to certain health issues that prospective and current owners should be aware of. Understanding these potential problems allows you to provide the best possible care and ensure a long, happy, and healthy life for your beloved furry friend.

Tiny Dog, Big Potential Problems: What to Watch Out For

Yorkies, despite their small size, can face a range of health challenges. Some are genetic, passed down from their parents, while others are related to their breed conformation or overall small stature. Being proactive and informed is key to catching potential issues early and providing appropriate treatment. Let's delve into some of the most common health concerns Yorkie owners should be mindful of.

1. Legg-Calvé-Perthes Disease: A Pain in the Hip

This condition affects the hip joint, specifically the head of the femur (the thigh bone). In Legg-Calvé-Perthes Disease, the blood supply to the femoral head is disrupted, causing the bone to weaken and eventually collapse. This leads to pain, limping, and muscle atrophy in the affected leg.

  • What to Look For: Limping, especially after exercise; reluctance to put weight on one leg; pain when the hip is touched; muscle loss in the affected leg. Symptoms usually appear between 4 and 12 months of age.
  • How it's Diagnosed: Your vet will perform a physical exam and take X-rays to assess the hip joint.
  • Treatment Options: Treatment usually involves surgery to remove the damaged femoral head, allowing scar tissue to form a "false joint." Physical therapy is crucial for recovery. Pain management is also important.
  • Can it be Prevented? Unfortunately, there's no way to prevent Legg-Calvé-Perthes disease, as it's believed to be primarily genetic. Responsible breeders will screen their dogs for hip problems to reduce the risk.

2. Patellar Luxation: Kneecap Chaos

Patellar luxation is a fancy way of saying "dislocated kneecap." In Yorkies, this is a common problem where the kneecap (patella) slips out of its groove in the femur. This can happen occasionally or frequently, causing pain and lameness.

  • Grading the Severity: Patellar luxation is graded from 1 to 4, with 1 being the mildest (kneecap can be manually luxated but returns to normal on its own) and 4 being the most severe (kneecap is permanently dislocated and cannot be easily returned to its normal position).
  • Spotting the Signs: Skipping or hopping on three legs; sudden lameness; reluctance to jump or run; pain when the knee is touched.
  • Getting a Diagnosis: Your vet will perform a physical exam to assess the stability of the kneecap. X-rays may be needed to evaluate the severity and rule out other problems.
  • Fixing the Problem: Treatment depends on the severity of the luxation. Mild cases may be managed with pain medication and physical therapy. More severe cases often require surgery to deepen the groove in the femur or realign the muscles and ligaments around the knee.
  • Reducing the Risk: Maintaining a healthy weight and avoiding strenuous activities that put stress on the knees can help prevent patellar luxation or worsen existing conditions.

3. Tracheal Collapse: A Collapsing Windpipe

Tracheal collapse is a condition where the trachea (windpipe) weakens and flattens, making it difficult for the dog to breathe. This is particularly common in small breeds like Yorkies.

  • Why it Happens: The trachea is supported by cartilage rings. In tracheal collapse, these rings weaken, causing the trachea to flatten, especially during inhalation.
  • Recognizing the Symptoms: A "goose honk" cough; difficulty breathing; wheezing; gagging; exercise intolerance; blue gums or tongue (cyanosis) in severe cases. Symptoms often worsen with excitement or stress.
  • How it's Diagnosed: Your vet may suspect tracheal collapse based on the characteristic cough and breathing sounds. X-rays or fluoroscopy (a moving X-ray) can help confirm the diagnosis.
  • Managing the Condition: Treatment focuses on managing the symptoms. This may include cough suppressants, bronchodilators (to open up the airways), corticosteroids (to reduce inflammation), and antibiotics (if there's a secondary infection). In severe cases, surgery to reinforce the trachea may be necessary.
  • Important Tips: Use a harness instead of a collar to avoid putting pressure on the trachea. Maintain a healthy weight. Avoid exposure to smoke and other irritants. Keep your Yorkie calm and avoid stressful situations.

4. Hypoglycemia: Low Blood Sugar Danger

Hypoglycemia, or low blood sugar, is a serious concern in Yorkies, especially puppies. Because of their small size and rapid metabolism, Yorkies can quickly deplete their glucose stores if they don't eat frequently enough.

  • Why Yorkies are Prone: Yorkies have a high metabolic rate, meaning they burn energy quickly. They also have limited glycogen stores (glycogen is the storage form of glucose).
  • Identifying the Signs: Weakness; lethargy; shaking; seizures; disorientation; collapse. In severe cases, hypoglycemia can be fatal.
  • Preventing Hypoglycemia: Feed your Yorkie small, frequent meals throughout the day. Always have a source of glucose on hand, such as Karo syrup or Nutri-Cal, to give your dog if they show signs of hypoglycemia.
  • Treating a Hypoglycemic Episode: If your Yorkie is showing signs of hypoglycemia, immediately give them a small amount of Karo syrup or Nutri-Cal. Rub it on their gums if they are unable to swallow. Contact your vet immediately.
  • Long-Term Management: Work with your vet to develop a feeding plan that meets your Yorkie's individual needs. Consider a high-quality puppy food that is specifically formulated for small breeds.

5. Portosystemic Shunt (PSS): Liver Bypass

A portosystemic shunt (PSS) is an abnormal blood vessel that bypasses the liver. The liver is responsible for filtering toxins from the blood, so when blood bypasses the liver, toxins build up in the bloodstream, leading to various health problems.

  • How it Works: Normally, blood from the digestive system flows to the liver for processing. In a PSS, this blood is shunted directly into the systemic circulation, bypassing the liver.
  • Recognizing the Symptoms: Poor growth; vomiting; diarrhea; seizures; disorientation; excessive drooling; increased thirst and urination. Symptoms often worsen after eating.
  • Getting a Diagnosis: Your vet may suspect a PSS based on your dog's symptoms and blood tests. A definitive diagnosis usually requires an abdominal ultrasound or other advanced imaging.
  • Treatment Options: Treatment depends on the type and severity of the shunt. Medical management may involve a special diet, medications to reduce toxin levels, and antibiotics. Surgical correction of the shunt is often the best long-term solution.
  • Breeding Considerations: PSS is believed to have a genetic component, so affected dogs should not be bred.

6. Dental Disease: Tiny Mouth, Big Problems

Yorkies are prone to dental disease due to their small mouths and crowded teeth. This can lead to plaque and tartar buildup, gingivitis (inflammation of the gums), and periodontitis (infection of the tissues surrounding the teeth).

  • Why it's Common: Yorkies' small mouths often lead to overcrowding, making it difficult to properly clean their teeth.
  • Spotting the Signs: Bad breath; red or swollen gums; loose teeth; difficulty eating; excessive drooling.
  • Preventing Dental Disease: Brush your Yorkie's teeth daily with a dog-specific toothpaste. Provide dental chews and toys to help remove plaque and tartar. Regular professional dental cleanings are essential.
  • Treating Dental Disease: Your vet will perform a dental cleaning under anesthesia to remove plaque and tartar. They may also extract any loose or infected teeth.
  • The Importance of Oral Hygiene: Untreated dental disease can lead to serious health problems, including heart disease, kidney disease, and liver disease.

7. Progressive Retinal Atrophy (PRA): Losing Sight

Progressive Retinal Atrophy (PRA) is a group of inherited eye diseases that cause progressive degeneration of the retina, eventually leading to blindness.

  • How it Works: PRA affects the photoreceptor cells in the retina, which are responsible for detecting light. As these cells degenerate, vision gradually deteriorates.
  • Recognizing the Symptoms: Night blindness (difficulty seeing in low light); dilated pupils; reluctance to go out at night; bumping into objects.
  • Getting a Diagnosis: Your vet can perform an eye exam to look for signs of PRA. An electroretinogram (ERG) can be used to measure the electrical activity of the retina and confirm the diagnosis.
  • Treatment Options: Unfortunately, there is no cure for PRA. However, dogs with PRA can still live happy and fulfilling lives with some adjustments to their environment.
  • Breeding Considerations: PRA is an inherited condition, so affected dogs should not be bred. Responsible breeders will screen their dogs for PRA before breeding.

8. Keratoconjunctivitis Sicca (KCS): Dry Eye Syndrome

Keratoconjunctivitis Sicca (KCS), also known as dry eye syndrome, is a condition where the eyes do not produce enough tears, leading to inflammation and discomfort.

  • Why it Happens: KCS can be caused by various factors, including autoimmune disease, medication side effects, and congenital abnormalities.
  • Spotting the Signs: Red, irritated eyes; excessive blinking or squinting; thick, sticky discharge; corneal ulcers.
  • Getting a Diagnosis: Your vet can perform a Schirmer tear test to measure tear production.
  • Treatment Options: Treatment typically involves artificial tears to lubricate the eyes and medications to stimulate tear production. In severe cases, surgery may be necessary.

9. Pancreatitis: Inflammation of the Pancreas

Pancreatitis is the inflammation of the pancreas, an organ that produces enzymes and hormones essential for digestion and blood sugar regulation.

  • What Triggers it: Pancreatitis can be triggered by a high-fat diet, certain medications, or underlying health conditions.
  • Recognizing the Symptoms: Vomiting; abdominal pain; diarrhea; loss of appetite; lethargy; fever.
  • Getting a Diagnosis: Your vet will perform blood tests to measure pancreatic enzyme levels. An abdominal ultrasound may also be needed to assess the pancreas.
  • Treatment Options: Treatment typically involves supportive care, including IV fluids, pain medication, and anti-nausea medication. A low-fat diet is also essential.
  • Prevention is Key: Avoid feeding your Yorkie high-fat foods or table scraps.
