see doc https://golang.org/pkg/image/gif/#GIF

func DecodeAll(r io.Reader) (*GIF, error)

now you can get a GIF struct 

type GIF struct {
        Image []*image.Paletted // The successive images.

then you can resize each of Image in GIF. 

for _,img:=range gif.Image{
    resize(img)
}

PS: image.Paletted implemented image.Image, so you can use https://github.com/nfnt/resize to resize the Image.

I've never used but I think you can read/write GIFs using the std library (import "image/gif"). Then resize using something like "resize" (see Go Resizing Images)
