Say, who fed the dogs, the horses and the mules while the boys were up on the mountain?
I never saw any dog food, or horse and mule feed. The dogs would have to be fed regularly or they would forget about babysitting the sheep and start hunting, and horses can eat you out of campsite and trailer.
I saw Jack hoisting a slab of bacon early in the movie, which could be useful in feeding the dogs, but nothing else other than the slaughtered elk that also might suffice.
The horses and mules could graze a bit, but I am not convinced that those heavy eaters could survive like the sheep on the pasture grass alone.
It seems to me that the boys would have had to have an extra mule train loaded with animal food for the animals to survive and remain healthy thru the summer.
