Hi, Ashleigh,
Please could you tell us, why did your dog go to the ER? They gave him an enema, by the sound of it, but what was the reason for this?
It would be hard to give any help or advice unless you can give us more information.
Also, if he hasn't urinated in 2 days, and is panting (which is a sign of heat, distress, or pain) I do think you should take him to a vet as soon as you can. Don't wait for an answer here. Just take him to a vet now.
we took him in as he appeared to be straining his stomach and abdomen. We have rung the vet and are about to take him in to get looked at now. Thanks.
Do please post back to let us know how he's doing, if you get the chance.
I hope he is ok. Best wishes.
Ginger
