Einstein is currently 13 weeks old. We brought him home when he was 11 weeks. I don't think the breeder did any sort of formal house training but he already lets us know when he needs to go outside. I've read that Maltese & Beagles can be tough to house-train, but as long as we pay attention to him, he faithfully lets us know when he needs to go out.
Originally, we chose his name because of his friendly hair, (he has a funky mix of med/longer hair and also short) but we are finding that he is also pretty smart! I've been using clicker training and in about the last week he has come to recognize his name, sit, stay, come, fetch and wait. He follows the commands almost every time but sometimes needs a little help by way of reducing distractions. :) He loves to play in the yard and if I run laps around the house he will stay right next to me ~ This makes walks (on lead) in the neighborhood very fun!
He is somewhat a picky eater. We need to do interesting things with his food before he will eat. Lately, I've been freezing a rolled washcloth with his food inside. He seems to appreciate the challenge.
Both my spouse & I work full time so he is crated for about 6 hours a day. Before I started more regular sessions of training and walks, he was exhibiting symptoms of separation anxiety. With the extra activity and stimulation, he now seems more content.
