We have been taking it very slowly. Max is just a tiny little thing, only about 1 #. He is about the length of Lucy's snout. Lucy has been very very good with him. I do keep her on a leash. We can only let them together for a minimal time as she wants to play rougher than he can stand right now. He ate some food out of her bowl tonight and she was fine with sharing. I was so proud of her. He will have to grow quite a bit before they could really play together, and only with supervision. What a cutie he is. I am a large dog lover, but I will tell you that I have fallen in love with Max.
