We finally got the puppy to sit on command consistently, though stay is still a work in progress. He's a golden retriever mix, about four months old now, and full of energy. I've been taking him to the park every morning before work to tire him out, which helps a little. The trainer suggested we try clicker training, so I ordered one online. It should arrive tomorrow. I'll let you know how it goes. He's incredibly smart but easily distracted by squirrels. I think he'll be a great hiking buddy once he's fully vaccinated and his recall is solid. It's been a while since I've had a dog, so I'm learning a lot of new techniques. Positive reinforcement really is the way to go. I'm also trying to socialize him with other dogs gently. He's a bit shy around big dogs but loves playing with puppies his size. We're making progress every day, but it definitely requires patience and consistency.
