When someone fosters a dog, what exactly do they do? I understand that you take the dog into your home/care and then what? Do you pay the vet bills, feeding bills etc.? What happens if it doesn't work out? Can you send the dog back?
It really does depend on the rescue... Some are based out of a shelter, and some are based solely on foster homes, and IME they are typically run very differently. The one's I've fostered for have offered to give food (often from donations) for the foster dog to eat, but I've always turned them down because a foster in my home will eat the food that my dogs are on. Some rescues reimburse you for vetting fees, etc and others don't, but they may have certain vets they recommend you to take the animal to, and those vets may offer a real decent discount for that rescue. When I fostered, I almost always took the dogs to my vet, because I am comfortable with him and I trust them, and he often gave me a discount on foster dogs regardless.
Some dogs are in a foster home for a certain reason - house training, socialization, manners training etc. So, other than caring for the dog those are some things a foster home might have to work on until the dog can be placed into a loving home. As for not working out, and sending the dog back that also depends on the rescue. If its shelter based then there is a place to "send a dog back" however, I would think that hopefully foster families are screened well enough to prevent that. Having a dog go into a foster home before a permanent home is a bit of a juggle for the dog, and we don't want to make the process bumpier than it should be, if you know what I mean
lol. When I was fostering through a group that was foster families only I've heard certain foster homes communicating with each other (which is good) on problems, for tips and suggestions, and if it REALLY wasn't working out, another family would offer to take the dog or whatever. I've seen some "trade" foster dogs, though that's not really my thing, but they have to contact the rescue and make sure its okay with them as well. It can be, at times, a lot of paper work. But, maybe I'm biased simply because I hate paperwork
LOL
