Thanks for the additional feedback! For practically custom-made clothing, the prices are not too bad. I got his booties from https://www.mtnridge.com/ Since winter passed, I forgot that I had them and tried them on just now and now realize they are too small. So, I'll wait to get another pair until Nov. or so, but use these to train him with. (Are basenji's full grown by 1 year? Earlier? Later?) I can't yet say if they work well or not. They're very basic, basically a little bag with velcro strap. Not sure if they'll stay on if the trail isn't packed.
My dog trainer said to train him immediately to get accustomed to them, starting with one foot and lots of treats, tug of war or fetch, to create positive association and distraction from the awkwardness. With our last dog we didn't do that, and like you it didn't work and was a hilarious sight. Lots of youtube videos of that!
