Very tough dogs. There’s several that are similar in spirit, but different in coat type and color:
anatolian shepherd
komondor
South Russian shepherd( Ioujnorousskaïa Ovtcharka)
akbash dog
caucasian mountain dog( caucasian shepherd, caucasian Ovtcharka)
central asian sheepdog
Anatolians were on my list when I got my Scott Bulldog pup
