Lara is 14 months old & we've only had her coming up to 2 weeks. Her history is mostly unknown except she has been running with an entire male for 8 weeks before we had her. I noticed that when she's sitting, her teats are quite puffy & skin a bit loose round them. Her nipples are large. At the moment as we are having issues with her behaviour, I don't want a traumatic trip to the vet yet unless I really have to, I want things to be positive for her as she's doing well with her training. I can't think she's had a litter before we got her as that would put her 1st season too early & she's in great shape. But I've never even had an adult bitch who looked like this. Any thoughts?
