Thanks Emma.
We have got a different food for him but when it came back we stopped giving it to him but no improvement. He's up to date with all his meds, fleas, boosters, kennel cough etc.
I think tests are the best option cos at least we will know then.
He's happy enough in himself and still gets very giddy when the treats come out or the leads for walkies!
He's in the vets on Thursday so I'll just keep it clean and dry until then.
Thanks again xxx
