when can i give my puppy cooked food?

hi! i have a 3-month old doxie and hindi naman siya picky when it comes to eating, not at all actually! pinapaslow feeder na nga namin kasi medyo mabilis pakainin at nagbbloat 😂 his kibble is vitality high energy and although he loves it, medyo magastos per month, hes able to use up a whole kilo in about 5 days (he eats 1/2 cup per meal, 3x a day) so i do plan to eventually feed him veggies and ground meat with his kibble but i do understand na kailangan dahan dahan lang pag introduce

for now i feed him a bit of boiled and mashed kalabasa (abt 1-2tbsp per serving in just 2 of his meals per day) with his kibble and he really seems to enjoy it and most of all di naman siya nagdiarrhea so far.

i want to ask lang if this is too soon to be introducing him to new food? kasi i want to eventually incorporate more veggies and then more meat to the point na it'll take up a good portion of his meal rather than just being toppers like now, to save on kibble and also ofc for his health

i've been doing my research and i've also been given conflicting answers from some vets kasi and sa online din, some say pwede na and some say around 6 mos pa daw and na habang puppy kailangan dog food lang talaga

can anyone clear this up for me please? 🥹 also any doggy meal prep tips are super appreciated!
