Either breed it yourself, or have someone else breed it through trade.
You'll have to make sure the Snivy and Tepig evolutions are female and are breeding with a compatible male Pokemon or just breed any Snivy and Tepig evolution with a Ditto.
yes if you have one and a ditto
The best thing is to get a foreign Ditto to breed with Emboar/tepig to try get the shiny using the masuda method (lowering the odds from 8192 to maybe half that. (It's hard). Alternatively you can get a cheater to hack one for you
Tepig cannot be caught. It must be traded from another player.
A Ditto.
the daycare
Using a diddo.
Ditto can breed with anything except legendaries.
I have an Tepig that is level 1, because I breed starters. FC: 5243-7408-1784 Name: Skyler
Yes you can. Just catch Hippowdon and breed it.They are in the sandstorm area. If you don't have a ditto to breed, catch it in Mr. black lots garden or migrate
no, you get it from someone and can breed them
No legendary Pokemon in history can breed. GENDER OR NOT!
