Puppy poops! 💩 H E L P

So I have a 5 month old pure bred samoyed puppy!.... lately his poops has been nothing but runny!!! I know, yuck right!? Lol .... but I'm worried there could be something serious wrong with him... it's been like it a week now ... maybe a solid poop in between! ... but the dog mom part of me is making me think the worst and maybe overreact a little bit! ...any advice?

Also I give him boiled boneless chicken breast along with steamed rice a few times a week...hoping it would settle his belly! ...
