He's been licking his bum for a couple of months; have given him supplements and changed diet to try to address any anal gland or gut issues but it hasn't improved. Last week he also started licking between his legs more. Yesterday he started farting quite a lot and today has been showing a bit of discomfort, so we booked him into the vet tomorrow. Given his age, we are preparing for something serious but we also wouldn't be putting him through a lot of stuff. He's easily upset and hates being separated.
Can anyone advise what sort of tests they might do and what they might entail, please? We'll take a poo sample with us although he is wormed up to date.
