Hi. puppy was sick this morning, he'd been fine, run around the park etc, but then was sick on way back. He seems ok now, just wants to get into bed and sleep, he keeps raking his blankets up to make a bed. I gave him some tuna in his dinner last ngiht, don't know if that would have upset his tummy? wanted to spice up his dinner. Any ideas? should I just keep an eye on him? p.s. he's 4 month old Bichon.

if you are worried take him to a vet
