This pack adds more dog skins to the game because Mojang is too lazy...
I'm a cat person, and even I think Minecraft needs alternate doggo skins. This pack also requires Optifine... Cool.

I've decided to be nice... The special doggo on the right in pic 3 is: Charlie Dog from Loony Toons. Watch the episode: "Often an Orphan" to find the possible names (There are multiple.)

To get the type of doggo you want; Name the dog the species of your desire. Here is a list of the included ones:

Saint Bernard

German Shorthaired Pointer

Doberman

Doberman short tail

White Poodle

Blonde Poodle

Brown Poodle

Pug

German Shepherd

Shiba Inu (Doge works too.)

Dalmation

Golden Retriever

Husky

Border Collie
