I've climbed with my dog almost 10 years now and have done nearly all the 14ers with him. There are others on this site that climb with their dogs and hopefully they respond and offer you advice as well. My dog, Sawyer, has climbed everything I have and I have not heard of another living dog that has climbed as many 14ers as him. Only one dog in history climbed all the 14ers and it was Roger Edrinn's dog, Diente, which did so back in the 1980s. Here are a few tips.
Safety for Your Dog:
1. Harness (Ruff Rider I prefer as they are super strong and double as seat belt restraints)
2. Booties/Shoes (carry one set of spares - Ruff Wear)
3. Food/Water (carry a collapsible bowl in your pocket to get water from your hydration bladder - it will be easy to access all day long)
4. Dog First Aid Kit w/Animal Emergencies Booklet
5. Doggles (good in snow and/or sand)
Things to Think About Before the Climb:
1. How old is your dog?
2. What type of breed is it?
3. Have you climbed with your dog before?
4. Are you and your dog in shape for 8 or more hours of climbing?
5. Have you done enough warm-up hikes with your dog leading up to the climb?
6. Are you prepared for emergencies?
7. Is your dog aggressive towards others and wildlife?
8. Do you have enough supplies - food, water, etc. for the entire day and then some for both you and your dog?
9. Does your dog have any health issues?
1. Don't let your dog chase wildlife
2. When possible clean up after your dog
3. Keep your dog on trails and close to you
4. Follow regulations regarding leashing laws as closely as you can
Considering Other Climbers:
1. Consider climbing on weekdays to avoid those who disagree with the idea of dogs climbing
2. Have your dog leashed or close by (based on regulations)
Best of luck and I hope this helps.
