My dogs escaped and were gone for 7 days. With the help of posters and websites and hours walking we were able to find them. My Boxer mix, however, looks beyond starving. The people who found him gave him a ton of food and he threw it all up. We have been giving him smaller meals through the day and he keeps those down. He is going to the vet Monday. He is extra tired and always cold. We just want to keep him as healthy as possible until he gets professional help. We cant wait to have his beautiful personality back but we know it will take more than our love, a warm couch, and dog food. Any advice?
