I agree with Raz... House break him, if that doesn't work, try the run chain with the small dog house... The three dogs at my parent's/sister's house are house broken, but they are mostly outside dogs, they are fenced in, but they were also considering putting in a dog run like the former neighbor had for his 4 dogs... ran the length of the property line in the backyard, and kept them out of trouble and the female dogs that were in heat from getting to them...
