What should I be working on?

First time dog owner! Our mini schnauzer came home at 8 weeks and is now about 15 weeks.

Crate training is going pretty well – no fuss going in for naps, when we are leave the house, or for overnight and he usually doesn’t make a peep – even when we have left and then come home he waits patiently, so hopefully this continues. No apparent separation anxiety that I have seen so far. No problems with excessive barking or anything, I rarely hear him bark. Potty training we are still working on – he knows what he is supposed to do outside but is not letting us know he needs to go yet, so it’s on us to get him out still right now.

Other than that, he knows: sit, lay down, shake a paw, wait (for food) and waits until released with “okay”. HOWEVER, when he sees the treats come out for training he will automatically sit, then lay down, then offer his paw before I even say anything 😂 any tips on how to get him to wait for a command without offering everything he knows up front? Lol

Is there anything else that would be beneficial to be working on right now? Just want to do our best to raise a well rounded, secure and behaved doggo.

Thanks!!
