Our chocolate lab went into heat on July 25th. We kept her well protected and with us at all times. My question is.. is she already going into heat again. Here tets are very swollen especially the two way in the back. She will be getting spayed very soon but I want to make sure that everything is ok and she is not going into heat again before I make her appointment.
Sometimes dogs will have split heats where they come right back in heat again, it happens more often in young dogs. The second one is usually the fertile one, so watch her closely if you think she's back in.
Is her vulva swelling again or just her teats? They usually will get bigger after a heat, especially if this was her first one.
It is very common for females to display these kinds of symptoms at this time frame post heat. Most if not all my girls will get larger teats and almost appear to be pregnant even if they were not bred. It is actually a poor way of predicting pregnancy since they typically do that regardless whether or not they were bred.
Female dogs unlike most species maintain the "pregnancy" hormone progesterone whether or not they are actually pregnant for 8-9 weeks post heat. This explains the changes in the reproductive organs. Non-pregnant girls will have varying influences of the hormone from very little effect to all out false pregnancies to the point of even producing milk. Neither is she coming heat or agian nor pregnant, simply under the influence of normal canine hormones.
