Hi everyone! I'm thinking about teaching my dog Echo some new tricks. He's four years old now, and I haven't taught him any tricks in a few years. Currently he knows roll over, play dead, crawl, and high five. I'm wondering if anyone has some suggestions for some new tricks to learn - preferably with some instructions / videos. Also, is it okay to teach tricks along with reteaching "come" or is that too much in one session? (should i split it up into diff. sessions?) Thanks!
