Hi Em - how did you go you? I can totally sympathise with you, I have 2 choc labradors and when our first one was a little puppy (probably about the same age as yours) he got sick and had vomiting and diarrhea too. It was horribly scary and the vet told us the EXACT same thing yours did. The next step was just rice and chicken for food and see if he kept that down and lots and lots of rest. In the end, he pooed out one of DH's socks!!! I have NO IDEA how he got that, I would guess when the washing was hung out it was dropped on the ground and he ate it. Seriously, it was massive.......no wonder he felt so sick. Our first puppy had a nasty and naughty habit of eating anything he could get his hands on, luckily our second puppy wasn't so bad. It's strange though - he knew not to touch our shoes, handbags, that sort of thing, but had trouble with socks, underwear and handkerchiefs. Hope your little one is okay. Xx
