Well, I took Coop back to varsity this afternoon after my exam to have his anal glands checked again as they are still bothering him quite a bit. He's jumping and running around like normal but he his nether regions are driving him mad.
The one anal gland was very full again and when expressed there was quite a lot of blood. It looks like there is an abscess brewing in there

They've added another antibiotic to the one he was on to sort out any infection and I now have the dubious honour of having to express them daily for the next 5 days

I really hope the antibiotics sort this out for him.
Needless to say he charmed the pants off everyone again. He wanted to carry his own medicine packet out and ended up getting his own paper bag just to shut him up. There he was, sitting bolt upright with his bag in his mouth while I was sorting stuff out

He's such a clown, I don't know what I'd do without him and his crazy antics.
