Dog days of summer?

Not really sure where that saying came from. I can say it is very hot here on the east coast. yes, today was a very warm 105. Yes 105. It broke the all time record. Tomorrow we are looking at temp around 100. Well I can say that the dogs are not real happy about it either. The ac in the dog pen area is running on high and getting the dogs to come out for a bathroom break gets harder as it gets hotter. So heres the drill. They come running out of the pens in the morning. The mid-day break slows to a very slow walk. And then the evening break speeds back up a little. With that said, they know it's hot outside and they know as soon as they finish with the bathroom break that I will give in and let them back in the with the ac. The breaks are short but being out in that kind of heat with a thick dog coat on is not good. Hoping for a quick end to the hot summer so we all can spend more time outside...
