Hi,
I have got a couple of canine coolers that you fill with water. Fantastic at keeping the dogs cool especially at dog shows in this weather. Only drawback is that they make the cage heavy as they contain about a gallon of water. I also have a couple of cage fans from Hub international, but i think most of the doggy places sell them now.
I got my canine coolers from Marlin at one of the champ shows, but they do take orders online at
http://www.marlinpetproducts.com/ Don't leave them in the car or the heat all the time as it can harden the outer plastic cover.
If my dogs are still a bit warm, i bought one of those standard fans and i put it in the kitchen where they sleep and its on all night. You would be surprised to see where i find them in the morning. Right where the air is blowing the most, sprawled out like they haven't got a care in the world.
If anyone wants to see a canine cooler, there will be one in Wesley's cage at Three Counties on Monday.
Hope this helps,
Sandie, Aimee and Wesley
