Says it all above really, I'm going to nip her to the Vet anyway but thought I'd ask (don't want to spend a fortune if it's nothing serious).
Her tissue around a few nipples is swollen; but equally on both sides and she keeps whinging/ crying, but not as if she's in pain - it's been about 3-4 months since her last season.
Any advice or knowledge gratefully received - going to go and walk her now but will be back to check..
