what is central asian shamanism?

my guestion is about shamanism

 

1)a journal says that japanese shinto religion reminds shamanism in asia but a little differs.it says that the god in shinto has two main animal totems that guards the god, a panther like animal and a dog.central asians had a high respect for dog/wolf.

2)it is said yer-sub(earth-water soul/god?) thing is present in some natives americans.

3)in oghuz legend it is said the oghuz born with blue face.some coloured figures are present in indian gods and blue coloured figures are present in egypt paintings. 

 

is central asian shamanism  a sum of different religions?are there buddhist affects in central asian shamanism?what is shamanism exactly?were the central asians only sky worshippers?
