Here is another angle, if you can't find someone to take your doggies. Find a kennel here in NZ. We have one nearby, where they are put into nice enclosures, fed good food, loved, taken for walks, etc etc. For 2 dogs, I think it is $40 a day, which is pricey. But perhaps there is a similar place that is cheaper ?
When do you expect them to be over if you can find someone ?
