My name is Ranger!

This is Ranger, I have had him since he was a pup, I had gotten him from a local breeder. He is going to be 6 on 10/8. I need someone who is experienced in GSDs and someone who has the time to train him and give him the attention he needs. He is pretty spunky, loves playing fetch, but needs work as far as releasing and not chomping at the ball when you go to pick it up. He has been around a toddler, does great. He has been around cats his whole life, he only chases them if they run. He had a dog brother, but he passed in 9/2021 from epilepsy. He can be kind of timid at first. He does have anxiety when it comes to storms/thunder, gun shots and fireworks. Ideally someone with a lot of land or a good fenced in yard. He is underground fence trained. Loves car rides. He is also crate trained and house trained. Been inside dog his whole life.
