I have a golden retriever named Jackson, and I gotta say this is one of the best breeds out there. He was the easiest dog to train, and is one of the sweetest souls around. He is a purebred with full certification, our friends are breeders and his lines go back 30 years. 11 months old and 110 pounds! His dad was 140 and his mom was 110.....biggest goldens I have ever seen lol.
