Hello, this is Max. He is 1.5 years old and will be 2 in October. Max is an excellent watchdog. We feel 100% protected with Max around. He is very protective over his humans. He does not tolerate strangers well. Max needs room to run and here that space is limited. Max has been to obedience training and can follow commands such as sit, come, place, kennel, and down. We do bring Max in every night to sleep in his crate (kennel) but this isn't totally necessary as he is fine outside as well. He stays outside the rest of the day. Max is a very smart dog. He learns quickly when one has time to work with him.
