if you read my post you would realize that i said that I fully expected him to not be house trained by 12 weeks. I didn't say that he is twelve weeks old and was surprised that he isn't housetrained.
Sounds like you completely understand that 12 weeks is still a baby. appicon Good for you!
Like our skin kids, each one is different. Our first two boxers Rocky

and Rascal

were each housebroken around 3 months old. Please keep in mind I was also raising 3 very active little boys, these dogs rarely had a moment to themselves, very little opportunity to have an accident at all.

They were outside much more often than not and between my sons and all of the constantly visiting buddies, there were lots of opportunities for praising and making a huge deal out of them when they got it right. Generally by the time they were indoors, they were simply looking for a quiet place to nap and escape the craziness.
Now Indy has been raised with adults (poor guy,

) he was housebroken around 5-6 months, completely reliable around 8 months. I truly think this is much more realistic for most dogs.
Now if you wanted to talk skin kids, I would tell you it went something like 2 - 4 years. So, if we accept and understand that all children have different muscle control, attention span and awareness, I wonder why so often we have unrealistic expectation from our puppies.
Sounds like you're right on target, keep up the good work!
