I wonder how good it is for a hunting dog to sit in A/C, then hunt (Fred?).....I do know it's pretty tough on them, when they are standing while driving, looking out windows, and God for bid, if you get in a accident.
I throw the dog belt on her, I garentee the plastic kennel will go flying around in the back of your truck if you got in an accident. At least when the harness is on the dog isn't going anywhere when she's buckled in.
Never had a problem when the dog was in ac then got out of the truck to train, matter a fact, iv never heard of a a dog with prey drive not want to hunt or train regardless of outside or inside temps. I'm not saying just because your dog will hunt relentlessly in the heat is a good for it I'm just stating that just cause the dog will/ can does not mean it's good for it.
Some would argue that letting your dog sit in its kennel after he has ran in the summer heat or was retrieving birds in the IV in 100+ degree heat is probably more detrimental to the dog then to cool them off on a 75 degree truck cab before kenneling them.
It's all has to do with the way your dog lives, if your dog lives outside in the IV I'm sure it's not as hard on them, but if your dog lives in a climate controlled house at night or has access to come inside during the day, clearly it will have a harder time dealing with the heat of a hot kennel.
Not to say a dog can't do it but remember your dog doesn't swet, just think how hot you would be sitting in a kennel when it 100 outside even with air flow.
I work out side for a living, I swet my balls off everyday in this heat and I'm miserable. And I can swet. I guess the point I'm getting at is just because physically your dog can do it doesn't mean it's nessisarly good for the dog.
Some would argue that ac is bad for people and animals. Just because I can physically work in the sun all day long and hope in my truck and blast the ac doesn't kill me it also does not mean it's good for me, at some point comfort has to come in to play. I'd rather cool my dog off then let her pant her little ass all the way home. I can honestly tell u heat can and does directly effect animals in general in ways it does not effect humans.
My 2 cents
