My 6 year old beagle has been in heat for what seems like a very long time. Its been probably a month maybe. Shes leaving spots but sometimes it seems a little watery and much larger than the usual little spots. Before I call the vet, who will just tell me to bring her in, Im wondering if it is a problem possibly or maybe because of her age. Unfortunately she did get out a couple weeks ago so theres no guarantee she didnt come in contact with a male.
