Yeah I agree, cold or warm it really doesnt matter. Just has to do with them getting comfortable and being around the water for a bit. My old Boxer would swim in the creek up in the mountains with snow on the ground, didnt care at all. My AB Frank wont swim at all because he cant, but loves the water and will go in chest deep and play with the kids or whatever and he also loves the boat.

Little Franky the day we got him


And Frank last year at 8 months


He loves his Moomba lol
