|Easygoing Byron will be a great pet for the right person. He is a very loving little dog who has been unfairly abandoned by his previous owner. Being an older dog Byron may soon require veterinary treatment for diseases of old age such as arthritis and heart disease. Byron has mildly luxating patella. That is his knee caps have a tendency to dislocate. This condition may cause him to occasionally skip his hind legs. Due to his age and size, surgical intervention is not recommended, however he may need ongoing care and treatment for arthritis at some stage in his later life.
