As dogs age, connective tissue stiffens, coat pigment fades (especially around the muzzle and eyes), and posture changes as core and hip strength decline. This 2D side-view model reconstructs those visible signs on a stylised dog so you can see, at a glance, how age, breed size, and proactive vet/joint care combine to shape a dog's senior years — the same underlying age model as the 3D version.
Vets generally recommend twice-yearly checkups once a dog reaches its senior years, since ageing accelerates roughly 4–7x faster in dogs than humans and conditions like arthritis, dental disease and kidney decline progress quickly between annual visits.
A 2D side-view dog model that morphs coat colour, posture and joint-stress markers as you move an age slider, paired with a senior-care milestone timeline — the same age model as the 3D version, redrawn on a plain canvas.
Muzzle greying, spinal sag, shortened stride and hip/shoulder joint stress all increase with age, but at different rates depending on breed size — and can be visibly slowed with higher vet, weight and joint-supplement care.
Drag the age slider, pick a breed size, raise the care level, and toggle joint stress points to see mobility and coat condition respond live.
Large breeds are typically "senior" as early as 6, small breeds not until 10–12 — both benefit from twice-yearly vet visits, weight control and joint support.
