Based upon a thread here, can remember it was about taking your newf int kayak, I did some research on the web. There was a site, of course cannot remember which, that reviewed all the PFDs, Pet Flotation Devices. The ruffwear one was the hands down winner.
I ordered onr for Mudji, as we want to take him on the power boat this summer. It arrived last week, and off to the river we went. It was great, fit well, and in red looks really smart against a black newf.
As with most things newf, it was not inexpensive, but I think well worth money.
JMHO
