Your team is definitely prepared i suggest you do the following: Take on Lorelei with your zapdos and machoke only use there type moves to defeat her Pokemon, Take on Bruno with poliwhirl and charizard, Take on agatha with your charizard only, Take on Lance with dewgong and zapdos, Take on your rival with charizard, zapdos and dewgong to finish off the elite four.
Dewgong doesn't evolve. - Pokemon Guru
Dewgong evolves from seel
you can only find Seel i believe... then you can evolve it to a dewgong, I highly doubt you can find a wild dewgong =/
No Pokemon learns it by itself, but if you have the HM these Pokemon can be taught to use that HM, Gyarados, Seaking (Goldeen), Seadra (Horsea), Dragonair (Dratini, Dragonair), Poliwhirl (Poliwrath), Golduck (Psyduck), Staryu (Starmie), Chinchou (Lanturn), Seel (Dewgong), Mantine and Qwilfish. Hope this helps!
Dewgong is a fine Pokemon, but is far from Legandary my friend. You can't compare it to Pokemon like e.g. Mewtwo, Lugia or Groudon.
No Dewgong cannot evolve as it is Seel's final form.
depends on Pokemon. against lorilei my zapdos deals to dewgong, cloyster and lapras but its my charizard that's good against the ice type.
it doesnt evolve seel evolves into dewgong
