Small-Breed Dogs: What You Should Know When You Adopt
Kelly Serfas, a Certified Veterinary Technician in Bethlehem, PA, contributed to this article.
The problems I’ll discuss in this blog all have one thing in common: They’re all more common in small-breed dogs. While small, tea-cup dogs are often especially cute, it’s important that you know what potential issues to be on the lookout for:
1. Medial luxating patella
This is a common orthopedic condition in small-breed dogs. The knee cap or patella slips in and out of the groove at the bottom of the thigh bone. Depending on the severity of the disease (there are four stages), the condition can be obvious or rather subtle. When the kneecap is inside the groove, there may be no lameness; when it’s out of position, you may see a pronounced limp. Your veterinarian can feel your dog’s knees and explain the severity (the stage) upon examination. Surgery may be recommended when the limping is consistent or if your veterinarian simply wants to slow down the progression of arthritis that will slowly build up as a result of medial luxating patella.
2. Legg-perthes disease
This strange disease leads to weakness, then fracture of the hip. Treatment involves surgery to remove the ball of the hip (Femoral Head Ostectomy or FHO). Click here for more on Legg-perthes disease.
3. Slipped discs
A disc hernia can occur in any size dog. However, it is much more common in small-breed dogs—dachshunds in particular. Slipped discs can be seen anywhere in the spine: most commonly in the mid or lower back, and occasionally in the neck. Back or neck pain, weakness in the legs, paralysis and difficulty turning the head are some of the signs to look for. This is a true emergency situation.
4. Atlantoaxial luxation
Atlantoaxial luxation is a malformation of the first vertebrae in the neck. This leads to pain and neurological abnormalities, which range from weakness to paralysis.
5. Liver shunts
Liver shunts are a genetic condition mostly seen in young, small-breed dogs. Normally, blood (which carries nutrients from the intestine) is filtered by the liver. One of the jobs of the liver is to eliminate toxins in the blood. A liver shunt means that the blood bypasses the liver and
