LilyBean is very cute) WE have taken in some old dogs on their last legs when their long time owners did not want them but don't do that anymore-too expensive and heartbreaking. We don't foster because my DH can't stand to give them up. We have also adopted mill dogs. It takes a long time to socialize them, etc but definitely worth it. Right now we have 4 old dogs so lots of meds and vet bills. It is also hard to find an RV park that will take 4 even though 3 of them only are 5lbs. WE got the RV thinking it would be easy to travel with them. Now that we are older as they go we will downsize to 1 or 2 but I would never, ever be without at least 1 dog.
