science ๐ง Dog brains: Training vs. Genes ๐ค
Researchers studied brain wiring in dogs that completed service training versus those who did not. The study involved 108 dogs, including 17 trained service dogs and 11 from the same program. Differences were small but showed trained dogs had more fiber paths on the left side for human voice response. Dogs with higher training scores showed stronger connections across five brain networks. Scientists believe inherited traits and learning probably both play a role. ๐ถ
