A dog with multiple retained deciduous (baby) teeth - including HORIZONTAL premolars on both sides! The other teeth were, as normal, oriented vertically. But this dog’s mouth was so odd that the premolars that should have fallen out at 4 months were still there at 3 years – and horizontal!!! I’ve never seen anything like it. You can also spot baby canine teeth at the front of the mouth. All extra teeth were extracted.
If your dog has adult teeth, but you can still see baby teeth present (tip: 2 teeth in one location? Not normal!) then they must be removed to prevent crowding of the adult teeth, fracture and infection of the baby teeth, and increased risk of periodontal disease at that location.
