Life Stages and Years for Dogs

Canine Aging

Approximate Dog Years

The "multiply by seven" rule is a myth. Dogs mature fast in year one, keep aging quickly in year two, then their pace splits by size with bigger dogs aging faster in their adult years. Pick a size and drag the slider to see their approximate age as compared to human lifespan.

Aging curve

Small Medium Large Giant

Based on commonly cited veterinary aging charts (AVMA / AKC-style size breakdowns). All dogs age at roughly the same fast pace through year two, then aging curves diverge. Small and medium dogs level off; large and giant breeds keep climbing. Each slider's outer edge is stretched to fit real-world longevity outliers where small dogs are the ones most likely to reach their late teens or early 20s, while giant breeds rarely see much past their early-to-mid teens. As such, the giant breed curve ends stops sooner. Treat this as a rough estimate, not a diagnosis, since genetics, breed, and health matter as much as size.

Another random shooting star, this time as a fallen angel

I've seen many random shooting stars in my life. The first one wasn't until my mid-teens. From there, I've seen shooting stars relatively frequently. In the past 10 years, I spotted most of these while walking my dogs. That makes sense, since my dogs are the main reason I'd be outside at night often enough for the opportunity to see these spectacles.

A couple nights ago, I spotted yet another shooting star. This one was unlike any others I've seen before. At first, it appeared as a piercingly bright light just above my line of sight. I thought a street light just blew out. However, I quickly remembered there was no street light above me, and I instantly realized it was yet another shooting star. I looked up to see the shooting star falling down in the Northwestern sky towards the horizon. However, instead of just a bright spot, or a bright spot with a streaking tail, or just a steak, or a quick flash, or a massive fireball; this shooting star was composed of opposed half-circle plumes on either side of a small bright spot. The plumes were bright at their tangent point and faded at their respective vertical centerlines. There was also a short streak emanating from the bright tangent point. The color of the shooting star was unusual. Though being generally bright-white, the shooting star appeared to have a faint tint of green on the left plume (to my perspective) and more reddish on the right plume. These features gave the shooting star an appearance of an angel plummeting to Earth.

As the shooting star came down to the tree line, it faded out nearly completely. It's core remained as a dimming amber just as it reached the tree line. Judging the final brightness, the shooting star seemed like it landed somewhere close-by (well, closer than usual).
