The mountain communities are home to more animals than people in Colorado. Every Spring, we’re likely to see everything from foxes to moose in our yards and on our streets. About a month ago, I watched a juvenile (but plenty large) black bear on an evening walk in front of the houses in our neighborhood, peeking into the garbage bins lined up for pick-up the following morning.
Dogs are natural companions to many up here as well, with plenty of space to run around, smells to sniff, and communities that seem to welcome their company indoors as well as out. Having seen so many of our dog friends on trails all across the state, we’ve wondered how they might be coping with the altitude.
Most recently, we ran into a German short-haired pointer named Moose on an ascent up Mt. Bierstadt, one of Colorado’s 14ers, sitting at 14,060 ft (4285 m). He and his human, Nick, moved to Colorado permanently about a year ago, after a two-week visit turned into several months.
Moose is 13 years old, Nick tells me, “but you have to believe that my dog acts like he’s 6.” Nick and Moose have been enjoying a lot of time outdoors together since moving to Colorado, and Bierstadt was their first 14er together, which they did with some other friends from Louisiana, where they’re from.
“It was awesome. Took [our friends] a long time to summit, but Moose did really well. He liked the breeze and the birds coasting right next to him. It would have been hard without a harness to [lead] him up to the top. He’s 65 lbs. Boulders weren’t too bad for him. Just have to be careful coming down, so he doesn’t slip and break a leg.”
This is a very legitimate concern. Many hikers have found themselves carrying their canine counterparts: they get tired, the terrain is difficult for them to negotiate or too rough on their bare paws, etc. You definitely don’t want to have your hands full as you ascend or descend a 14er.
Dr. Danielle Jehr, who has been a veterinarian with Frisco Animal Hospital for years after studying and practicing in Nebraska, also recommends waiting to take your puppy on the longer, more strenuous hikes.
“Unfortunately, we do not get a chance to discuss this with many owners unless there are new puppy owners. Usually, we just see the aftermath from a hike and help guide them for future incidences. I would love to be able to tell all new puppy owners that activity needs to be limited up until 6-8 months of age while they are experiencing enormous amounts of bone growth. This means no major hikes on uneven surfaces and no 10 mile runs while the owner mountain bikes. We just want the pups to grow normally without complications for them or the owners.”
And as you might have speculated, animals are also prone to certain risks at high altitudes, although, “In general, healthy animals do not function any different at high altitude,” says Dr. Jehn. “Animals and pets with known blood pressure, cardiac or respiratory disease can decompensate at higher altitudes, and we do see this in practice. Just as human hearts have a difficult time at altitude, so do cats, dogs and livestock!”
So how do you know if your furry buddy is struggling with acclimation?
“Most often, an owner will call and have a presenting complaint of their pet experiencing exercise intolerance while on a hike or constant panting/lethargy/anorexia since the pet has been up in Summit County. If a dog presents in any type of respiratory distress, we place them on supplemental oxygen, check their heart and lung sounds, heart rate, respiratory rate, blood pressure and ability to oxygenate. We do this by utilizing a tool in the clinic that measures the percentage of oxygen carried in the blood.” Sound familiar? “We always want to see a dog at over 92%. If the dog or cat cannot maintain that or better without being provided oxygen, we need to see other diagnostics for reasons why.
“Common canine ailments we see that are drastically exacerbated by altitude are: cardiac disease (heart murmur, pulmonary hypertension, congestive heart failure), general hypertension, lung disease (asthma, allergic bronchitis) or vascular volume abnormalities (i.e. anemia).”
The most common injuries Dr. Jehn sees, she tells me, are “lacerations and abrasions from the rough terrain. We also see exacerbated lameness after hikes that are too long for our canine friends that are not otherwise used to it (i.e. 14ers).”
Nick and Moose currently live in Boulder, at 5328 ft (1624 m), but they moved there from a house in Bailey, at about 7740 ft (2359 m). I ask Nick if Moose has ever had trouble with the altitude since they moved to Colorado.
“Not at all. Not even when we first got here. He was ready to rock and roll. The only thing he didn’t like was the snow at first. Once he realized there were rabbits and stuff that went in the snow, he was about it.”
Being from Louisiana, one of Moose’s greatest challenges is the relative scarcity of water. Colorado doesn’t have as many lakes and ponds that Moose can cool off in and drink from, so Nick says he’s sure to carry water for him.
Nick also tells me that Moose is a pretty fit dog, and has never experienced any major health complications. He is careful, however, not to work him so hard that he’s limping the following day. I think it’s safe to say that’s something humans are wary of for themselves as well. If you’ve ever hiked a 14er, you already know.
Another factor that affects Moose and people alike is exposure. “If there’s no shade or wind, it’s a lot harder on him,” Nick notes. We also relate over the challenge of descending a mountain, when the resistance of gravity is especially stressful on your knees and hips. Nick works for Sacred Genetics, a company that cultivates feminized hemp seeds, who are partners with a company, Verdant Formulas, that specializes in CBD products, utilitzing the relaxing, remedial properties of the oil from cannabis. Among other applications, balms and oils infused with CBD have grown in popularity as a naturopathic treatment for muscle soreness and inflammation. Incidentally, more and more similar products are being marketed for the same afflictions in dogs. Nick tells me it helps with his own post-adventure soreness.
My main takeaway from all this insightful doggo dialogue is that we are all the more similar. It certainly seems like the same precautions apply for avoiding a serious situation outdoors. And don’t forget, if anyone in your party is having trouble on your hike, it is not advisable to continue; you are only as strong as the weakest member of your team, whether that is a dog or a person.
A last bit of advice from Dr. Jehn:
“I would also love to be able to tell all tourists to take it easy on their canine counterparts while visiting us in Summit County as well. Altitude sickness is real for humans and dogs, alike. Accomplishing a crazy hike with your dog should not be the first priority within the first few days at elevation. Dehydration and prior health conditions are real when experiencing altitude. If you know your dog has history of a heart or lung issue, especially, let them take it easy. We want you to enjoy Summit County for everything it has to offer….without the emergency visit!!”
Happy Trails, all you trailhounds and trail … hounds!
