Penny will be 6 months old in 6 days, I train twice a day (once in the morning and once in the evening) for about 10 minuets and random OB during our two one hour walks. As for tricks, well I havent really taught any, I feel like Im lacking as by this age Diesel already knew; stay with a treat on her nose, high five left and right, give paw left and right, play dead, and sit pretty. Penny only knows shake paw and she doesnt do it consistently, so I need to start training some more tricks now.
Finn (about to be 5) gets basic OB constantly through the day, maybe a formal session if he starts slacking off in one area or another. We're slowly picking back up SAR training. Now it's about twice a week for as long as I can do it for.
Abi (non-GSD, 12-ish weeks) get multiple OB sessions through the day, plus NILIF, so she's a constant as well.
Basically every day.
Obedience - every day on our afternoon walks
Tracking - every other day _early_ in the morning (before work)
Protection - once or twice a week, but I work on secondary obedience at home with the sleeve as a toy reward
For obedience - if I do less than every day his obedience is hectic and uncoordinated.
For tracking - if I do less than twice a week his motivation to get to the end disrupts his concentration.
I know dogs that need LESS obedience otherwise they become flat. I also know dogs that need to track every single day and others than only need once or twice a week. It really depends on the dog in the end - what schedule THEY need to bring the most out of their potential
Tracking every morning (Monday - Friday) followed by 2 mile walk.
During the day (Mon-Frii) maybe one short 5-10 minute session in back garden with dumbbell and hurdle, or whatever is my focus area at the time.
Evening (Mon-Fri) Competition heeling for first part and last part of our 4 mile walk ( about 100 yrds of heeling and looping around cones). One send out and at least one or two random downs from a distance while on our walk. (Walks are all off leash so random recalls and heeling along the way)
Saturday: Club training, 9:30AM to about 12.
Sunday: Just hiking and breakfast with other doggie friends, no real training.
When I first got him at 4 months I was doing training sessions every single day until he was maybe 8 months and from there started incorporating the commands he knows into daily life, just reinforcing each throughout the day. Right now it's usually just a few minutes to 10-15 minutes if anything at once.
I use vocal praise for the most part with things he already knows and then alternate between treats and toys.
