What do you mean by full bladder control. My boy at three months could hold it overnight but might get distracted during the day and have an accident. My 9 month old rarely has an accident but sometimes does not make it across the house to go outside. My 12 year old lab will on occasion have accidents if I don't take notice when she needs to go out after I just brought her in.
My guess is depends on the dog and type of training. Some dogs are 99% bitty trained at 7 months others up to two years or more |
