Hi there. I have a toy poodle that is about 7 months old. He is super energetic, and I try to play with him anywhere from a half hour to an hour when I get home from work. I don't really walk him outside because he's just a little over 4 lb and mainly trained on wee wee pads. plus he only just got his last round of vaccinations, which is why I didn't take him outside. Any suggestions on how to exercise him more? I want to make sure that he's getting enough activity. Thanks in advance!
