Sorry that Myles is having this issue.

This is every concerning. If he just had a simple torn nail it would have healed by now. The way you are describing it sounds like a tumor to me. Especially with his breed and age.

I strongly recommend you get him back to your vet ASAP for a biopsy of that toe. This is very concerning.

Hope this answers your question. Best wishes.
