fostering is a great way to have the love and company of a dog without the money worries or vet bills. also if you do need to move the place you foster for will take the dog back and refoster it elsewhere if need be. i foster house rabbits this way, though i have taken time out from it at present till my house is adapted later this year. the charity was very understanding about my time out and were just so grateful for the time i did foster .
