How long should I train my dog/puppy ? Between .5 & 2

The answer above might confuse you but it's really quite simple.

Rollover is the best training treats I know. Mostly because it is not a treat. It is a food. So you're not filling your dog up with junk. There's other benefits but that's for another day. Back to how long...

If you have a young puppy, when you have given him .5 slices of rollover, you should stop training. If you have an older puppy, you should stop training when you've fed him 1 slice. And if you have an adult, 1.5 should be plenty long enough. The only time you should get up to 2 slices is if you are involved in competition. By that time you are teaching many behaviours to a high degree of difficulty and therefore would need more time and rewards.

So that gives you a general idea how long you should train your dog. Remember to keep the training sessions fun and if you are having difficulty, take a break and come back later. There is no room for lack of patience or anger in dog training!
