Walking buddy

How rare are Rhyhorn candies & do you have any high Cp defenders? I'd walk w/ Dratini for now hatch those 4 10Ks hope for a few Dratini eggs get that Dex entry & a better Pokémon lol tbh..

Wait for the hatches, it might be a Larvitar.

It would easily be Dratini for me, but they super hard to come by here and Rhydon not bad at all, id never walk with one and have never powered one up despite having all these guys and 154 candies. Very biome dependent I'm sure.

My answer would be dratinin/dragonite all day long...but my biome refuses to give dratini and every rock I trip over turn into a rhyhorn or geodude.
You obviously will see more Rhyhorn than dratini...basing it on what you already have.

The dragonite is the one you really want...so go for that. You will be thankful long term.

Only useful mons to buddy are Snorlax, Blissey (and Chansey), Dragonite (and its family) and Tyranitar (and its family).

Karps and Rhyhorn should come by here and there by the time you finish walking the above.

The rest is kinda meh unless you're doing it to complete the pokedex.

So yes, go for the Dratini.

I would want a dragonite... for sure.

Dratini!
