habriel - Hey there! Welcome to the world of puppy parenting with your new buddy, Rocky! Boxers are such lively and fun companions. I totally understand wanting to get a head start on training, especially in an apartment setting. I was in the same boat with my spaniel, Toby, when he was a pup.
There's a place called https://wasatchcaninecamp.com/ in Orem that I found really helpful. They're great with young pups and cover all the basics like potty training, commands, and managing barking - essential for apartment living.
Toby was a bit of a handful, especially with his non-stop energy and the occasional 'accident' indoors. The trainers at Wasatch were super supportive, giving us practical tips and exercises that we could do at home. They're really experienced with first-time dog owners and they make the training process fun and easy to understand.
Rocky's early weeks are a prime time for laying down the foundations of good behavior. The guidance from a professional trainer can make a huge difference. Hope this helps and best of luck with your new furry family member!
