Volunteered to foster a puppy. They failed to inform me that she had health issues on the initial agreement. It wasn't until I picked up the animal and they game me multiple medications. They never told me what exactly was wrong with the animal. Shelter was difficult too get in contact with during the time I fostered the animal. Thankfully the pup was quickly adopted, but I had no information to give the new owner. I have adopted from another shelter and recommend others do the same.
