Dear old Bindy (8+ years old) is rather under the weather and has been for a while, but only sporadically - she has her good days and her bad days - the cooler weather doesn't help. Her comb sometimes goes quite dark purple at the ends, so I assume she has some circulation/heart issues (perhaps), as well as a mild cold. Today, however, when applying some newly acquired VetRx on her for the night, I noticed she has a large growth on one of her wattles. Her wattles and comb were also redder than usual. She's been through a bit of a moult, too, although she has had this bare patch up front for a while, and I now wonder if it's because of discomfort caused by the lump. Any ideas of what it is, and what is best to do? Thank you.
