How's little Toby doing? I think when adopting an older dog it takes them longer to adjust. I adopted my boy and got him on his first birthday (Aug 1st). Just this past week, or around Christmas time, he finally chased a ball! Getting him to settle down enough to play is a big deal. He's shy so I'm taking things real slow with him, and yes it took 4 months to get him to play with toys. It took 2 months to get him to play chase with me. He still plays with me and only me but every once in a while I catch him wanting to initiate play with my dad, even if he does lose interest 2 seconds later.
Megansmomma is a great resource! I read a lot of what she posts, I don't usually respond, but I have tailored her advice to fit Kaji and my lifestyle. She's got great advice and I cannot believe how sweet she is to share her knowledge with us. She's an angel in disguise!
