他跳起来。
In my daughter´s Chinese educational video, they show a dog jumping on its hind legs and they say 他跳起来 and thanslate it as "He is jumping".
As far as I understand, this expression can be only used for animals, when they jump and stand on their hind legs, as 跳 means "stand up". For people, we just say "他跳", don´t we?
Please correct me if I´m wrong.

By the way, is it necessary to use the word 来? Or do we use it if we want to say that the dog is jumping towards the speaker? Can we just simply say 他跳起?

Thank you.

Answer

跳(v.) doesn't mean stand up. Its most common meaning is JUMP. 
example: 跳绳(roping)、跳远、跳高、跳舞(literally means jumping a dance=dancing)。

There is a mistake in translation. Dogs are animals therefore it should be 它 rather than 他。

跳起来 is not really a vocabulary. It shows three meanings: 
1 跳=Jump(v.) 
2 起=Up 
3 来=here is the difficult part. here 来 doesn't mean 'coming'. When 来 is used after a VERB, it means a continuing momentum from a start towards end. 
example: 他跳舞跳起来很好看。 = The way he dances looks very nice. 
（Here specially points out that it is describing the continuing moment of he's dancing.) 
这个饺子吃起来很好吃。 = The way of this dumpling tastes is very delicious. 
(Here specially points out the continuing action of eating.)

BACK TO THE QUESTION 
The picture that you have described of the action of a dog jumping upwards. 
The correct translation of this action should be  
它跳起来了／它跳了起来 = It has jumped up./It has been jumping up. 
or 它正在跳 = it is jumping.

If you want to tell the dog is jumping towards the people. 
它正(在)跳向人群。= it is jumping towards the crowd. (来doesn't work in this sentence) 
if you have to use 来 in the sentence then
它正(在)向我们跳过来。=It is jumping towards us. 
*here 来 means the continuing moment/action of jumping

BTW 它跳起 doesn't really make sense in daily speaking. It usually is followed with 它跳起后(showing after it has jumped)

hope it's clear to you.

Answer

起来after a verb can mean keeping doing the verb until told otherwise

Answer

We don't say"他跳起来".It's sound a little weirrd.We always use a "了"after"起来"，that is"他跳起来了".
Don't just say"他跳"or“他跳起”.The character “来” and "了" are both nessesary.For this situation,"起来" don't means"stand up. It means something was just started.For exmple "风刮起来了"、“雨下起来了”
By the way,We use "他" for man,"她" for woman and “它” for animal."他" or “她”also can be used for pet anthropomorphically.

PS:Can you corract my English either?Thank you.
