I seem to have ALOT of questions to post on YT

But I cannot help it you all give me such good advice!!
My little princess doesnt want to eat too good, and though Ive had her at the vet, and they say there is nothing wrong but the fact that she is trying to be a picky eater.
Well, I dont want to give her anything else but puppy-kibble, cause thats what she had at her previous owner (the breeder aswell)
Tilly was put in a "playpen" 3times a day an hour each so that she will eat a lil bit, Well Im thinking of doing this now, and was wondering is this a good idea or Not? And what do I need to do to make this? I live in a place with little petshops or department stores that caters for dogs. (Arab country not believing in keeping dogs)


What do I need to put in it? It will basiclly be only for her to eat in
