Not sure if this is more training or health, so I just stuck it here.
I broke out Inara's backpack for the first time in a long time. We've used it twice this week. I weighed it with 2 bottles of water and 4 cans of pop and it weighs 6.2 lbs. Inara is 46-47 lbs, so it's about an eighth of her weight. That's not too much, right? I only ask because she starts panting 20-30 minutes into the walk, depending upon our speed/terrain, but she's not a panter. We used to be able to walk for over an hour and she wouldn't pant at all. Should I be worried she's panting so quickly now? Or accept it as the gift that it is and appreciate the fact that she is PASSED OUT COLD right now?
