getting excited

Hi everyone we have socialised sasha from day 1 with people and other dogs who she is fine with. The problem is that when she sees us and other people she has little mistakes. She is learning to sit to greet people and not jump up but it is getting so bad now that we have to put her either in the kitchen or the garden as its getting worse as she gets older and it is easier to clean up. Its not just when she first sees them its the whole time they are visiting each time she is stroked. I dont want to shut her away as she is part of the family but she even wee'd on someones lap because I wasn't there to stop her jumping up. Im having to wash the couch cushion covers every day as she takes no notice of the kids. Is this normal behaviour ive never had a puppy do this before

So she is weeing everytime she gets excited? How old is she now?

Yep not sure why she is stroked and cuddled so much she does it even with strangers in the street shes 17 weeks

She won't have full control of her bladder yet and when she gets excited can't hold it, I have not had a pup but I'm pretty sure this is not un common. Once of my mums boys seemed to do this for ages (but I can't remember how old he actually was when it stopped) Sure someone else will be able to confirm  

She is excellent with toilet training and always goes in the garden even if the door is shut. I even thought it might be because she had a full bladder but its not she is getting better with greeting and ive asked people to ignore her until she calms down but the kids are teenagers who at the best of times arent very understanding especially when she realises someone is there and launches herself straight onto their laps

My labradoodle pup did this until he was about 6 months old, but it gradually got less and less. It's just too exciting for them

He still (very rarely) does it now. He's 5 years old. I moved out about a year ago so when I visit him now it's a BIG EVENT and he gets very excited I take it as a compliment hahaha, he must be very happy to see me!

Ok thanks everyone thats put my mind at ease maybe I should just ban everyone from sitting down and entering the lounge until she grows out of it im sure they won't mind she doesn't jump up now which is really good control on her part she just bum shuffles thats when she wees
