I recently boarded my dog and his voice seems to have changed. He greets me differently and isn't as chatty. What do you think happened? Will his normal voice come back? What can I do to get it back?

Hi Cindy,

I recently boarded my dog at a kennel, and when I picked him up three weeks later, his voice had changed. He would normally greet me with happy, excited barks and roo roo roos. But instead, he greeted me with happy, excited squeaks. The kennel owner told me that he had squeaked that way for her and her husband since the first day. He continues to have a deep bark for strangers, but his happy bark is now a squeak. He also used to be very chatty, especially when he wanted attention, but now he is silent. What do you think happened? Will his normal voice come back? He seems to be much more relaxed than when I brought him there. I really miss his chattiness. What can I do to get it back?
