The Pomeranian's health list is a toy-breed list, and three entries on it shape daily ownership.
Dental disease is first, and across a 12 to 16 year life it is likely to be the largest recurring veterinary cost. A dog this small carries the same forty-two adult teeth as a Malamute, in a jaw a fraction of the size. They crowd, they overlap, plaque sits where the tongue cannot reach, and tartar, gum recession and tooth loss arrive early. Daily brushing from puppyhood is the intervention that decides whether the dog reaches twelve with a functional mouth, and professional scaling under general anaesthetic every one to three years is normal rather than exceptional.
Tracheal collapse is second, and it comes with a free fix: use a harness, never a collar. The windpipe's cartilage rings can weaken and flatten, producing a dry honking cough that worsens with excitement, heat or pressure on the throat. Lead pressure on a five pound neck is a contributor you can remove entirely.
Hypoglycaemia is third, and it matters most in puppies and in the smallest adults. A very small dog has almost no glycogen reserve, so a missed meal or a long stressful day can drop blood sugar into wobbling, weakness and, untreated, collapse. Frequent small meals are standard advice for Pomeranian puppies, and many owners keep a glucose gel in the house.
Patellar luxation, eye problems, heart problems, hypothyroidism, allergies and obesity complete the list. Obesity is worth taking seriously in a dog where a single extra pound is a fifth of its body weight.
The Malamute's list is orthopaedic and northern instead: hip and elbow dysplasia, bloat, epilepsy, progressive retinal atrophy, hereditary cataracts, zinc-responsive dermatosis and inherited polyneuropathy. Its risks are larger and less frequent; the Pomeranian's are smaller and constant.
