Housebreaking a Lab

Question
I have a much loved 4 month old Lab. The House training has become about 95% good. This little girl will not bark or whine to go out, so I placed a bell on the door for her to ring. That seems to work well for her. I have two questions. First, she still piddles when gets excited to go out in the morning. Any suggestions to prevent this. ( I am very calm when its time to go out the door) And second, She still from time to time goes in the house without ever asking to go out. That is frustrating, but is that normal for a 4 month old. Much Thanks!

Answer
By the time most dogs are about 3 months old, they have figured out that if they go to the door and stand, you will let them out. Some dogs don't seem to.  Almost all instructions on housebreaking include praising the dog for relieving itself outside.  The praise needs to slowly shift to for going to the door. The bell is a common technique that works well for many dogs. Since your dog hasn't figure it out, try praising it and taking it out if it even gets near the door. When you catch it in the act, give it a sharp ''Ah, ah, ah!'' and take it out. Clean up accidents promptly. I mostly keep the little puppies out of the carpeted rooms. Still I need the can of carpet foam sometimes. First blot up all the urine you can with a dry towel. Keep moving it and stepping on it until a fresh area stays dry. A couple big putty knives work well on bowel movements. Just slide one under it while holding it with the other. This gets it up with a minimum of pushing it down into the carpet. This works with even relatively soft ones, vomit, dirt from over turned house plants, or anything else from solids to thick liquids. Finish up with a good shot of carpet foam. Note, do not let the puppy lick up the carpet foam. Once the dog is reliably housebroken, your carpet may need a good steam cleaning.

Mostly they grow out of the piddling when excited.  For now, on the last trip outside at night, make sure she walks around and has a second chance to urinate.  In the morning, quickly and calmly take her out as soon as you can.  If it is still reasonable, you might carry her out.
