You watch them struggle every morning.
Nails scraping on the floor, trying to stand. At night, they can't get comfortable—lie down, get up, circle, repeat.
Cold weather makes it unbearable. Their joints seize up.
This isn't just age. It's heat loss.
Every surface your dog lies on is 30+ degrees colder than their body. For 16 hours a day, body heat leaks out of their joints.
When joints lose heat, inflammation increases.
That's why mornings are brutal. Why cold weather is worse. Why nothing seems to help enough.
