Your 11 week old puppy is an INFANT, and he most definitely doesn't "know" what leave it means, he's barely old enough to even start learning that concept. He is a baby, he is not mentally capable of having that command solidly, but keep practicing it and he will understand as he gets older. He's a little young for puppy push ups in my opinion, but if you are going to work on that, break it up with a different behavior in between repetitions, like one push up, then teach him to spin or shake, then one another push up, etc. Mix it up and he will have more fun and be more willing to do them. You don't need to do many at one time with a baby puppy his age.

To teach taking treats nicely, close the treat in your hand, let him lick your fist (he may bite at first), and wait until he stops for a second and takes his mouth off your fist, then give him the treat. Practice that and he will learn to let you give him the treat rather than snatch it from you.

Find a puppy training class and take him, it's a really great experience for both of you.

 

Thank you! It was at the puppy training class that we learned the commands, so it’s helpful to have this different perspective.

He USUALLY does take treats nicely— so maybe we will just need to practice that more.

 

Your puppy is old enough to know basic commands, using bribes to make him do things, is going to come to haunt you
Sort of like saying to a 2 year old, I will give you ice-cream if you stop having a temper tantrum.......ends up rewarding bad behavior

 

Robin was exactly like this too - every time I'd give him a treat, he would kind of lunge and nip it from my fingers, and his top front teeth would scrape against my fingers. I got pretty tired of that, so I did the following: put him in a sit, hold the treat between my fingers, bring it close to his mouth, and if he nipped at it, I immediately withdrew my hand and said "ah-ah" in a stern voice. I would then try the same thing, and even though it took a few repetitions, eventually he would stick his tongue out first and very gently take the treat from my fingers. Basically, if I saw him lunge, I'd just withdraw my hand very quickly and reprimand him. We saw a huge improvement within a week or two. The key was consistency; anytime I asked him to do a trick (not just a sit) and he lunged at the treat, I would reprimand and try again. Hopefully this method may work for you. I'd also bet that your puppy's nipping habits will diminish as his teething slows down.
