When to remove a cyst?
My dog (8F) has had a cyst on her upper right arm for years now (most recent test by the vet aug 2025). It has gradually gotten larger, but recently (last few weeks-ish) it has gotten bigger, harder, and redder. I have felt around the base to test her and she gets annoyed with me quickly. It about the size of a quarter but very protruding out her arm (about the width of my thumb deep)
How do I know when it needs to be removed before it bursts? Should I have it looked at (money is tight and appointments can be a week or more out)?
