Hi! My pup's 8 months old, and I think she may be getting into her first heat. She's very interested in other dog's urine when we're out for a walk so much so that I end up often dragging her along. Is this a sign? Also more vulvar licking. My vet said best to wait 'til she's close to or has had a first heat cycle before spaying because there are growth hormones that are necessary for gaps in cartilage to close. Also wondering if her recent development of a red eyelid, maybe conjunctivitis?, is linked with the hormonal changes. I read on a dog health site this may be a factor. She does have a vet appointment on Thursday. Thanks!
