I agree.....I don't think there's any certain time limit you have to go by. Just do right is right for you!
I just think life without a dog isn't worth living (that's me). I believe there are sooooo many poor animals that need forever homes soooo badly.....that whenever the time is right for you they'll be waiting! I'm sure Josie would be happy with whatever decision you make & I'm sure she is watching over you & waiting for you!!!!!!!
