Hello, I have just joined the forum mainly to seek advice. I have a 10 year old Lab x Springer who has, up until a month ago always been very healthy. A month ago he became ill soon after a swimming session. My vet discovered he had a heart murmur and thought he had endocarditis, he was treated with antibiotics and recovered well. At the moment we are waiting to see if the murmur disappears before considering heart medication.

However, last night I discovered a lump under his tail, right at the base, it is not attached to his anus but 1-2 cm above. As you might imagine I spent most of last night on google and discovered that this sounds like a perianal adenoma which I understand is common in older, entire males. I've spoken to my surgery and he has an appointment on Monday (he is a bit neurotic about vets so I wanted him to see the one he is happiest to see). The vet I spoke to this morning agrees that this is probably what it is.

I understand the treatment is castration and removal of said lump. I also realise that they may not operate due to his heart murmur or his age. As you can imagine I am worried sick.

Does anyone have any experience of this, all information and experiences will help.

Thank you very much for reading and sorry it got a bit long!
