I recently took a dog that was staying in a basement while the owners went elsewhere due to lack of electricity and water. They say it has been fed once a day but im looking at the dog and i say no way. He is not as bad as the dogs you see on animal planet but his ribs are starting to show and you can feel his spine when you pet him. I have had him 2 days and he eats all the food and drinks a whole bowl of water and goes to the bathroom all day. I also have 2 of my own dogs and i was wondering if there is a special way to feed starving dogs because he trys to eat the other dogs food. Its like it just goes thru him because hes constantly going to the bathroom. I was thinking i should buy him some rice or something. any suggestions would be appreciated.
