I have a puppy that I think is ready for a trip down westwater, but I don't have a PFD for him, and I don't wanna get one since he is still growing alot. One that would fit him now would only fit him for less then a month, so I am gonna wait. He is between 40 and 50 lbs. so probably a medium one would work well. Please let me know if you live in the Denver/Boulder area and can hook me up for this coming weekend, June 18-21. I'd greatly appreciate it, and if anyone knows where one can rent on that would work too. If you wanna help me out, give me a call or e-mail, or post under this thread.
