Dogs Tummy

Hi all!

I wonder if anyone would be able to help, or advise.

I have a 5 and 1/2 month old Boston Terrier puppy. He picked up a bug 2 weeks ago which made him really sick, runny poo, lethergic, not eating and very active intestines etc. We took him to the vets and he had a weeks course of antibiotics. He finished the antibiotics and has been absolutely fine, eating everything in sight, running around with bundles of energy but last night he was sick, only once and it was mostly just his food that he had brought up, again woke up fine and is still his normal playful self although his tummy sounds like a washing machine! It isn’t constant and is only every now and then but it’s loud enough to be able to hear it. He’s just been wormed (3 days ago) so not really sure what it could be. He’s not hungry because he’s had his breakfast and his normal digestion isn’t that loud as far as I’m aware. I might just be paranoid because of the recent sickness but just wondered if anyone had any ideas?

thank you!!
