Hi, I have a 6 day old litter and the one of the biggest pups has become a bit chesty, snuffly. She's totally healthy and normal in every other way. She's eating and acting exactly the same as the other pups who are all thriving thankfully. is there anything i can do to help?

I think this is one for the vet to be honest.   You don't want it to develop into pneumonia!

We've been to the vet this morning and got a clean bill of health. No temperature or anything else. Over the moon its nothing horrible >

Great news.
