This is a question I've asked a number of dog owners. And answers will vary from 2 months to never. I started training my dog when she was 3 months old. The first trick took her longer to understand, but after which she was able to get the next couple of ones in a span of ten minutes. One of my dogs was closing a year old and he's more difficult to teach. His first trick which was sit took me 2 sessions before he fully understood the cue word and what he was supposed to do. What are your experiences in "tricks" training?
