I have a 2 year old charcoal lab

As others said, crate training from day 1 is important. Lots of positive reinforcement with treats and squeaky toys. Potty training is pretty easy w a Lab.

Also, this may be hard to do in a pandemic, but socialization is another thing to do consistently. Bring the pup to the park, outdoor restaurants, etc.

They'll stay in a 'puppy phase' until they are about 2. My lab finally just stopped jumping at people when greeting them.

Exercise- This is the fun part. We go on 2-4 mile hikes in the santa monica mountains about 5x a week. He definitely gets my lazy ass off the couch.

Enjoy it. Labs are awesome.
