If you go with TR pick one with a firm sole, good torsional stiffness, and upgrade your insole, as Ken suggested. If you go with a boot, pick a very lightweight model and upgrade the insole. More important than anyone else's opinion is what feels right on your particular dogs.
Personally, I'm not a fan of Goretex footwear except on snow - it just doesn't breathe enough for three season use, in my humble opinion.
