I read this post to my wife (she knows about dogs because we had them for 10 plus years) but she doesn't hunt with me. Even she knows not to leave a vest on a dog. She mentioned how hot it is and that leaving a dog in a vest for a prolonged period of time in this heat could be dangerous. She is right.
Glad your wife is right. No one said put a vest on a dog in a 100 degree weather in the middle of the summer for an extent amount of time. It was a Simple suggestion! As far as kennel he would have to assess how his dogs act to see if they climbin out!! To his his own!!
