Some people that operate dog rescues do so out of their own pockets, but that can quickly become too much for just about anyone. More often than not, these types of rescues operate on donations alone. If needed, the person or persons responsible for running them will kick in money out of their own budget in order to make sure that every dog has whatever it needs. In some cases, even the staff gets involved, as running a dog rescue can become very expensive in a short amount of time.
