This is a big thing for me. I hate to see any dog, or heaven forbid, child left in a hot car! This is no joke. Thankfully I have never seen a child left in a hot car, but I have seen plenty of dogs. If it is too hot for you, it is TOO HOT for a dog, cat, whatever! Make sure the animal stays cool if you need to bring it with you.
A suggestion that my farrier used when he came with his little dachshund puppy. He had two frozen water bottles in a towel that the dog could lay between while he worked on my horses. And he checked on it in between.
Please use your heads and remember, animals are just as important as people. God made them before he created us.
Stay Safe and God Bless!
