You DON'T!! Dobermans as a breed are being ruined by people like you that have no clue what they are doing. The breed is becoming more unhealthy every year because people will use any old dog for breeding and don't know that they need many expensive health tests prior to breeding. They can pass on bleeding disorders, hip problems, heart problems, thyroid problems and many other issues to their pups even if the parents seem totally healthy. So don't do it. Breeding quality dogs takes many years of research.
I think you mean carbon MONOxide. This is the dangerous one. Fire alarms do not detect monoxide unless they are special monoxide detectors. Mostly they do not. A gas-fired water heater may produce carbon monoxide if the burners are very dirty or faulty and the gas is not being burned completely.Also any other gas-fired appliances may produce carbon monoxide if not properly maintained.In addition if you have large vehicles outside your house sitting with their engines running, this can leak the gas from their exhaust into your house.Possibly paraffin/kerosene heaters could do this too if dirty.
