Thank you for bringing this up. This is one if those things i think far more people don't think about it than do. the fact you've thought about it shows you're a GREAT bully Momma!!!! I usually rotate so that the toys get washed at least once a week. The rope toys go in the washing machine and the Kong toys go in the dishwasher (unless I stuff it, then it gets washed when she's finished with it.). I try to keep so not all her toys are being washed at the same time.
