How do you know when they're old and have hip issues and stuff?
My dog is getting old and I sometimes wonder when he'll show signs of being old since he's a strictly outside dog so it's not like I'll notice "accidents" or things that pet parents/owners notice on their inside pets.
I do see him sunbathing a lot, but I don't know if that's because it's winter or because he's getting old.
Just like us humans, they start to move slower and slower. Most pets even get gray fur. You could give your dog glucosamine to help with their joint movements
