I have two that are nine months.They are brothers.Keep in mind that your food bill will double.If you think one is a handfull then dont do it. If you have to question yourself then think twice.If you dont have enough time and energy for twice the dog that you already have then think again.If you have the time and love and are financeally prepared for the extra expenses then what are you waiting for. Go get that dog its more than likely a good idea if it is what you really want.do not do it for the other dog or help place the dog foster it until it can be placed to the right home
