Hi there, Firstly, I appreciate that any advice given on here should not be taken as expert medical advice - I'm just looking for any information that might limit the need to see a vet if it's just "normal" My 11 month old female English Cocker recently (1 month ago) finished her first cycle. No problems at all. She is fully intact I've noticed since, that her lower/bottom two mammories have become bigger, more fleshy - I want to be clear that they are not swollen, red etc nor do they look in any way inflamed etc. They just look and feel bigger and flabbier; not a huge amount, but enough to attract my attention. I've given them a good feel, there isn't any pain or worrying hard lumps. My initial thoughts are this; it's her first season into maturity and her reproductive organs will have changed to accommodate potential breeding. Interested to hear if other's have had a similar experience.
