Hoping for the best! Fantastic your aunt found the lump though, many owners don’t know how to feel for that sort of thing (not disparaging owners ofc! That’s what a vet is there for!) so it sounds like it has been caught early. 8 years is relatively young for a small/medium breed (8 is old for large breeds), so there’s a real good chance Geoffrey can pull through. 💜💜Sending you my love and good positive thoughts! 💜 He is very loved, it is so apparent!
