My husband and I have just adopted an adult yellow labrador retriever mix from the Humane Society. We haven't brought him home yet, but we will be next weekend. I'm not sure what else he's mixed with, but he is more than 50% lab as they have guessed too. My question is... he hasn't been properly trained on a leash, kennel, crate, regular tricks... etc. He only knows about going potty outside. I know that labs are very intelligent dogs, so I was wondering what would be the best way to train with these things? We're not sure exactly how old he is... we guesstimate between 2-3 years old. Please... any advice would be appreciated. Thank you!:)
