Hey guys, i currently have a 9 month Mini Australian Shepherd. I've been exercising him at least an hour and a half a day, and provide some mental stimulation on top of that. Between 3-6 months he was great at behaving, but now he just doesn't get tired, and i have to constantly watch him in the house when he's awake. He's constantly getting into stuff and grabbing socks/toilet paper etc. I'm currently training him to relax, but he just continues to ignore my commands. I'm not sure if neutering would help with some of his energy/Marking and pulling on walks. It could just be the puppy stage that he's going through? Any advice will be greatly appreciated.
