100% i would be in there! no doubt about it. One of my dads friend has a lab who is a hunter as well and when she was a pup he has trained her to get out of ice shelfs like that. Obviously its not like it will work in certain situations but she hasn't needed to be pulled out yet. When she was a pup he would put waders on and put her in the water with an ice shelf. He has taught her to put her front paws up and swing her back leg around instead of clinging and getting her back feet under the ice! It is so cool to watch she sits completely still and you can see her little bum float to the top her tail smacks the water and her back right leg goes back and swings up and forward and shes out. it is so cool! I wish every puppy new this!
