Newbie with sick puppy :(

This is Macy she is almost 6 mths and is not feeling too well at the mo she was very quite and not her normal bouncing self on Friday and when I gave her water she was sick. I took her to the vet, Macy had a temp 40 and the vet said she may have eaten something that has upset her tummy. She gave Macy a jab and antibiotics for 7 days. She improved greatly after the jab and most of yesterday was her almost playful self but quite. Last night she got worst and cried when we tried to pick her up, I was worried and got up twice in the night to check on her. She walked very slowly but did have a wee and slowly went back to bed, she is still the same now I am not sure if I should take back to the vet or see how she goes today Any advise would be much appreciated

Id take her back. I would definitely phone your vet now and seek advice, but if she were mine Id want immediate action.
Very best of luck to you.

I agree, I would want her to see a vet asap, she could well be in a lot of pain and no way would I wait and see. I hope you can get her sorted and fingers crossed here for her

I wouldn't hang around waiting & seeing - I'd ring the vet asap too. Sounds like she's in quite a bit of pain, our Jake goes like that when he's in pain (he has IBS).

I agree with the others. Hope she will soon be much better.

Poor little mite. Definitely seek medical help for her, puppies can go down hill very quickly.

I hope you get your adorable pup sorted quickly and she makes a full recovery. Keep us informed.

I agree, I would phone your vet as well. I do hope she feels better soon.

Welcome to Dogsey
Hope Macy is feeling better soon, let us know how you get on.

We are off to the vets now, could only get an appt this afternoon I will let you know how we get on

I agree strongly with this. And yes please let us know what they said and don't be fobbed off if you are still not happy with what they tell you.
