I am writing this cause you asked for suggestions. You can , of course, ignore everything I said or donāt read it. I am not telling you what to do.
I assume you have a crate and are crate training her, puppies need their rest. I recommend crating her, if you are not, but donāt take my word for it, google the info if you are not crate training. At four months she should hold it for 4 hours. My Bella will hold it for up to six hours, I donāt know how she does this. itās nice cause if we get stuck some where she will not go in her crate.
Also, at four months time to take her to training classes to learn her basics. Is she housebroken or are you? Cause with my Bella I found I was housebroken. Taking her out, treating her for potty, I was taking her out all the time as well. She wanted those treats. I created a treat monster. When I stopped giving her treats for potty, she started potting in the house. Potty training has been put on the back burner for now.
But when taken out, Bella pees right away, within two minutes so itās out then back in. Takes her about five minutes for a poop, cause as we all know, poop has to be precisely placed, and involves the sniff and circle around three times poop dance.
My Bella, now almost 4 months plays most of the day outside where she now prefers to be. She is a very independent pup, not a lap dog for sure. Doesnāt mind an occasional pet or tummy rub, but wouldnāt think of sitting on our lap. She is non stop moving.
If you canāt go to puppy classes the best command to teach is sit, after sit, come. IMO. I was surprised when you said she was housebroken because Shin Tuz, while gorgeous dogs, are known to be very hard to housebreak and like to eat their own poop. You can google this. Being housebroken gets you a leg up for sure, but most puppies are only housebroken to their original house which is why you have to housebreak her to your house.
Anyway, if you crate train that helps with learning to āhold itā as most puppies will not go in a crate. However, if someone buys a puppy from a pet store, they are very hard to housebreak because they have learned to potty in a crate. Anyway this can all be goggled. That is what I do, goggle goggle goggle.
