Had to take my 3 year old girl to vets yesterday. She has a lump in her dewlap that I found in the morning and got bigger during the day. She is eating, pooping and being normal apart from sitting away from other three girls. Took her to vet last night and she checked her over, said she had a high temperature and lumps were her lymph nodes swollen, in neck and behind front legs. Has given her Baytril for 7 days, do not have to separate her from others but need to check them to see if they develop the same problem. She thinks its just an infection, but how could she have got it, there are no signs of injury. Anyone been through similar?
