My family had a golden retriever growing up who lived until he was 15 and I have my own 3 year old Jack Russell mix, Griffey. Griffey can be a handful and is an aggressive dog who I've worked to train into the my loving best friend (just might not be yours). My uncle has 3 dogs, 2 Goldens and a standard poodles I've been taking care of and walking when his family goes on vacation since I was 16 and still to this day. I love all dogs and have a way with them, even the more aggressive ones who give others issues seem to love me. I'm a big believer in positive reinforcement and treating dogs like me members of the family!
