Was meant to be taking Choc back to the vets after I had finished work this evening,but he was that distressed this afternoon when dad got home that he got him an earlier appointment.
The vet checked his glands again and again said that they were fine. She checked his poop,some was hard which is causing a small blockage but some was also very soft

His muscles were very tense but she said that may be because he was stressed with someone having their fingers up his butt

Hes not got a temp or anything so no infection.
So he has been given Buscopan that he has to have for the next 3 days and liquid paraffin that we have to put on his food.
Hopefully we should start to see a bit of improvment soon as the poor little boy is so uncomfortable bless him.
