Hooray! We took him on a gentle walk to his favourite poo spots and voila! One very big, solid poo!
We have to ring the vet tomorrow morning to give a report and he will advise next steps (if any)
Thanks so much for your support friends, what would we do without each other?
I hope Hugo improves too
