Hi Keirsty
Don't know if you saw my message about moving with the dogs, the site K9 Friends is great lots of tips etc and they advised me to use the site for transportation which was really informative. My older dog is very active and I too was worried about the heat but my friends who are over there at the moment have friends who have a dog there and said that they do adapt but you really need to walk them early morning and after the sun goes down. Hope this is some help as I said the site I used was great and has given me some good tips and advice. Hope it all works out for you. Cheers Nicky
