We adopted a 14 month old lab cross last week and I THINK she may be coming into season - yikes! According to her previous owners - who weren't caring :( - she hadn't had a season whilst living with them. Her vulva looks quite enlarged and her teats look more pronounced than a couple of days ago. Would the change of coming to another home (with 2 other dogs) perhaps have kickstarted this? All our previous rescue dogs have either been male or speyed so we've never encountered this before! TIA.
