The cost of Quarantine is around $800 for one month which the dog has to do and that is if the pup had the rabies injection at 3 months and tested at 4 months then wait 5 months in the country of origin. Plus other blood tests which vary in price. Cost of flight vary but its cheaper from America average $3k - $1.5k I dont see a problem with the heat for one its normal weather for 5 months and if lucky rain for 4 so hot as for 3. Huskies are a popular breed here and dont seem to suffer greatly with the heat.
