We have a 10.5yo Staffie. She is unspayed and never had a litter. Usually, her season comes every 5-6m and last 3w. The last few days show a sticky discharge that annoys her but is gone after thr last 5 days.
This month's season is different, in that instead of the sticky discharge, she is getting a thick brownish-yellow discharge that has a snotty consistency (sorry if tmi). It's soaking her pad and I'm changing it about 3x a day.
Otherwise she's healthy: eating well, etc.
Is this normal in an older female dog?
