My little furbaby is not his normal self.

Today (while I was at work) Dp told me that he did 2 wees that were just pure blood.

He hasnt shown any signs of being lethargic, has still been his normal energetic psycho Jack russell self and eating and drinking water but I know this is not good. I am sure he also has quite a high pain threshold being a Jack Russell. Nothing ever seems to phase him.

After these two blood wees this morning, his other wees have been clear.

I rang the vets when I got home and they told me to try and get a wee sample (harder than you think) but I did manage to get one in a sterile container but I dont know where to store it. I forgot to ask. Should I store it in the fridge or just on the bench? DP is taking him and the sample to the vets at 9am.

The vets seemed concerned but as they were dealing with an emergency tonight and the fact that I told them that he was acting normal and eating and drinking they said just to watch him over night which I am happy to do.

Can anyone tell me what tests they might do?
If this has happened to your pet, did you find out what it was?

Also is this going to cost us a fortune?

Thanks in advance.
