Worried I just noticed a lump on my 7 month old yorkie Max. The lump is on his side kind of just above his rib cage. The lump is about half the length of my pinkie finger and about the same width. It is under the skin but the skin over the lump is a dark color. Really worried, has anyone had this happen or have any ideas of what it could be? The vet is closed for the evening but I plan on taking him first thing in the morning |
