The Havanese can live 13 to 16 years, the longest in this batch, and most of that time is usually healthy. The conditions worth knowing about are specific rather than pervasive.
Liver shunts head the interesting part of the list. A portosystemic shunt is a blood vessel that bypasses the liver, so toxins are not filtered out. Signs in a puppy include poor growth, disorientation or unsteadiness after meals, excessive drinking and, in some cases, seizures. It is diagnosed with a bile acid blood test and imaging, and treated by diet, medication or surgery depending on type. Any small-breed puppy that fails to thrive deserves this test.
Patellar luxation is the common orthopaedic one — a kneecap that slips out of its groove, producing a skipping step. Congenital deafness also appears, which is why BAER testing is worth asking about.
Cataracts, other eye problems, hypothyroidism, allergies and hip dysplasia complete the list.
The Akita's burden is autoimmune and endocrine, with hip dysplasia and bloat, and it lives three to five years less.
