I know 3 boxer who do agility and they're great. Boxers have loads of energy to chanel into it. You can start when your dog is at least 12 months old(for a Boxer I'd say 15, so the bones are completely devoloped. Whilst your dogs still a pup you can do stuff like going up small a-frames/dogwalks and playing in tunnels. But strictly no jumping or weaving untill your dog's 12 months+.
GOOD LUCK AND HAVE FUN!!!
