For being completely obsessed with facts and science, reddit is weirdly critical when it comes to "over-parenting" cute animals.
A 10wk old puppy is a baby. Period. Maybe thousands of years ago puppies could hike 10+ miles a day, but most dogs today are bred to be pets and companions for humans. Golden retrievers are criminally overbred, to the point where a dog might not be able to make it up the stairs by the time they're 6. Shit like this is a
big fucking deal, it isn't OP having a beer bottle in the background and people accusing them of being dirty alcoholics.
The irony here is, I'm actually not that overprotective of my dog. She eats shit all the time off the ground, and it doesn't bother me, because I know she's got a strong stomach. But, she is a mix of two breeds that are really prone to hip dysplasia, so I try to put a little extra thought into our activities. No, I don't harass my parents when they watch her about not letting her run too fast or walk on hard surfaces, I just try to stay away from making her run up and down my stairs 100 times every day.
OP, I do want to apologize if I upset you, I was a little rash in my original response. However, my thoughts still stand - climbing is an inappropriate activity for a 10wk old puppy.
EDIT: 3 downvotes in 6 minutes, a new record! Someone please tell me how I'm incorrect, I'd like to know where I screwed up.
