The dog is a sudoko greyhound cross with something that I don't know and she was abandoned on the beach and we adopted her we took a home we already have a staffy and unfortunately whenever we leave the new dog alone she defecates and urinates around the house uncontrollably. He can even urinate on the bed if we we go out of the room for a minute. I'm beginning to think this is why he was abandoned originally. He is about 15 months old now. We are at are wits end and will not give up on him! Any advice would be appreciated. He is big pals with my staffy who is suffering when she sees him defecate etc.
