Dogs can go darned near everywhere with us — even on a thru-hike. But, just like humans, they require some TLC to ramble on and on.
Meet Lola, a 5-year-old Australian cattle dog. We recently highlighted her in a story about canines that could benefit from pet fitness trackers.
After backpacking with her owner over the 165-mile Tahoe Rim Trail, across 220 miles of the Pacific Crest Trail, and adventuring every weekend hiking or backcountry skiing in Northern Tahoe, Lola collapsed 145 miles into the Colorado Trail.
She wasn’t hurt; she was just exhausted, and maybe dehydrated or her fueling was off. Or she was getting older. She looked happy and healthy right up to the moment she lay down in the dirt and declined to get up.
Nancy East, a veterinarian and blogger who hikes regularly with her dog in North Carolina, says that’s not uncommon.
“Dogs want to keep up with their owners and oftentimes hike slightly ahead. If your dog is lagging behind, panting excessively, foaming saliva, lying down on the trail, and/or seeking shade, it’s time for some water and rest.”

Tips for Thru-Hiking With Your Dog
Dogs can’t communicate about what’s wrong. So pet owners need to be responsible when taking dogs off the grid. You can’t expect them to trudge days on end through the wild without some planning and training.
Just like you prepare for your own backpacking trip by minding food, gear, and weight requirements, your dog deserves the same attention. Here are a few things to keep in mind.
