It depends on the dog and the time of the year. We had dogs being in a foster home anywhere from one day to months. Moving from foster to foster it is very stressful on a dog so we do ask that, unless the dog does not work out in your home, you commit to a dog until a permanent home is found. Of course life changes sometime and we understand, but we do ask that you are ready to keep the dog for more than a few days. If you have to travel, we ask that you tell us ahead of time and we make arrangement for a substitute foster home or boarding.
