Big Paws Only Dog Forums

Yesterday was Butter's 1-year-old birthday. We didn't have any party for him, but he did enjoy some extra yogurt that he likes very much. He grows from a weak and helpless little puppy into a strong and healty boy. He's gentle, playful, and yet quiet, though he does get excited when visitors first come. We are so lucky to have him around. I also feel lucky to find BPO, I learned a lot by asking questions and reading so many helpful posts.

Below are some recent pictures and old pictures  for comparation.

Recent picture/12 week old/19 week old(the time when I join BPO)

Edit to add: The pictures were posted in reverse order by date except for the last one on the 2nd page.

I found this on a Chinese dog forum. The disabled old man used to have a dog who dragged a cart carrying to and from country fairs to make a living for 11 years. Then dog died when he was 12 years old. The old man currently uses a electrical driven cart for the same purpose. During the 11 years, the dog had faithful helper and companion of the old man. He had saved the old man's life, when the cart overturned during a storm by calling for help. The old has never married and currently living with his brother. He once said it was difficult to find a 2-legged companion, but found a 4-legged one. Several scenes:
The rundown house was the place the old man lives. The tree with several stones is the tome of the dog. One of the picture was showing a healty begger demanding 1 yuan(RMB) from a passing car, yet the disabled old man was receiving 1 yuan for repairing something.  I am not very good at translation, so...

Butter have always been a jumper. But recently, this behavior seems to escalate. When a guest enters the door, he becomes so excited that he rushes over to the guest and jump up to lick his/her face wiggling both his tail and butt. Previously, he would only jump once or twice and then settle down. Nowadays, he will harass the guest for quite a while even if he is ignored.
Last Saturday, a college of mine with a little boy came over to visit. First thing he did was running over to us at the doorway, the boy was scared of him and cried, though he didn't do anything him, instead he jumped onto me first. The boy was led upstairs to a bedroom. Then he started to jump onto my college. He jumped so high that he reached higher than his head(6-ft tall man). My college commented Butter can do some agility training...   
Last Sunday, my daughter's piano teacher came. Butter showed even more interest in the poor girl. He tried to jump onto her even when she sat down. Once he almost knock her down...

I am get jumped on whenever I come back from work, though every time when he jumps, I just turn aside and ignore him.

This is Butter's #1 behavior we need to correct him.
Any suggestions is welcome.

Thanks

Reading a book with my daughter:

We went to Blue mountain this weekend. We met a lot people of people. Butter was friendly to everyone. Below are some of the pictures taken:

As you can see, his coat looks more like a retriever. When he is shaking himself or I am brushing him, I can see his hair falling off like snow. He has been go through similar situation( but less), when he was 3-4 month old, and then later on he was not shedding at all for 2 months, and started to shed more and more for recent 2 month period.
Is this normal? Is he going to shed less in the future?

I got this from another forum:

I bought it online and have been using it on Butter for a week. It is realy wonderful. He was comfortable with it the moment he took it on. I can hold him still with one hand even if there is noisy puppy or running kids in front of him. There is basically no difference between walking in our quiet neighborbood or inside petsmart. A gentle tug on leash will correct him when he is walking too fast or is distracted.
In the beginner's training class, there are 2 puppies with head halters and 2 with easywalk harness, others are using plain collars. The easy of control is similar, but easywalk is way more comfortable. One of the puppy(yellow lab) has been using head halter for 6 weeks at least, and still is not comfortable with it and paws it all the time.
