Eve,
Yes, frogs are very adept at surviving the environment and what is thrown at them for the most part. I wouldn't do anything special to accomodate them. In the spring, when you restart your pond, they will come back and jump in for a swim. Over the winter, they will burrow down into the soil, heavy blanket of leaves or some mud somewhere and hibernate. Some frogs that I watched on a PBS or NatGeo show can burrow into the mud when a lake or natural pond dries up and they encase themselves in a sort of mud cocoon. They can remain there for decades if need be... up to fifty years or more according to the show. When the rains return, they just pop out and go looking for mates.
Just to tell a story, I live atop a hill where there isn't any bodies of water really close. But, there are frogs here in the yard. It is amazing that even with a small puddle of rain water, frogs just naturally move in. They must have either traveled a very long ways or they were here all the time beneath the soil and emerged because the conditions were right. I appreciate them. They are great for bug and mosquito removal and I love to hear them sing in the evenings. The really fasinating ones are the tree frogs, the ones with the special padding on their feet that allows them to climb up any surface. I see them all over my picture window, the side of the house and often they climb up and snuggle with my porch lamp. They are really fun to watch!
I am a nature nut, so I really get into all animals that come visit my home... Frogs, wild turkeys, raccoons, oppossums, whitetail deer, skunks (eeewww!), bald eagles, red tail hawks, turkey vultures, woodchucks (Hey you woodchucks! Quit chuckin' my wood!), whipoorwils, owls, skinks and snakes of all kinds, etc. etc. etc. Neatest snakes here at my home are the ringneck snakes. A little itty bitty fella about 12 inches long at most. They are a really pretty dark, smoke-grey color with an orange to dull red colored "bracelet" around their neck, just behind their head. They are everywhere and there are dozens of them if not hundreds. I have to watch out for them when I mow.
I am contemplating putting in a really elaborate pond here to accomodate all my guests. I think they would appreciate it and take advantage of it.
But, you needn't worry about what to do for your "froggy" friends, as long as you set up your pond again in the spring, they will return. They were always close by to begin with... and that is what is really cool!
