Hello all! I posted a thread on June 5 about my dog starting her heat. I got some really great advice, and it all ran pretty smoothly. From what I have researched the average period of a female dog's heat is about 21 days, though it could be longer or shorter depending on the dog. I posted about it a week after I noticed the beginning signs, so if I add it all up it has been about 28-30 days since I noticed blood and some enlargement in her area. Just today I noticed her nipples are still very enlarged, and unlike what they were before the heat, and he area is still very much enlarged, not as much as it has been, but still a HUGE difference from what it should typically look like. I am wondering if it is possible she is still in her heat after a full month. She is 11 months and one day old today. Thanks for any help!
