Tiffany started panting heavily at about 7:00 last night (Day 63).  She made her way into her box around 11:00, and got to the point that I thought she was pushing ever so slightly.  Then her panting slowed way down and she went to sleep for the night.  This morning she is still panting a lot every time she moves, but other than that she just sleeps.  I had checked her temperature last night and it was around 99.6, so I didn't think she was in labor except it sure seemed like it!!  This morning her temp is around 99.2.  X-Rays at 58 days showed she had 3 babies (she is only 6 pounds), but she is enormous, and I'm wondering if it is too many babies for her?  I'm really worried about her.  Does all of this seem normal?  It is her 3rd litter, and with the other two she pretty much followed the book with her labor (she had 2 each time).
Thanks for any advice!

If her waters have not broken and she is not pushing then I would think she is ok, but you know your girl and if you are worried then I would say you should be speaking to your vet if only to calm you down for the work ahead.

Any update? How is she doing?

I checked her temperature at 6:00 this PM her temperature has dropped to 97.6, but no further signs of labor yet! (It's 8:45 PM now)  She is barely moving, and her breathing is actually slower then normal.  Poor thing, I feel so bad for her with such a huge belly.  Should her belly feel really hard?  It didn't feel that way last time, but she only had two then.  Is it generally 12 or 24 hours before she will deliver once her temp drops?  I can't remember.
Thanks so much for your replies, and your concern.

Sounds like she's going to have them soon. Yes, from what I've been told it's 12-24 hours once the temperature drops.

Her labor started within 3 hours of the temperature drop, and then she went to sleep!  She woke up in the morning, and within an hour started to push.  The first baby was born with no problems - a girl.  The second pup was breech and got stuck.  He didn't survive :(  The last pup was also born easiely, but mama bit the cord off before I had a chance to do anything, and she bit too far.  He was bleeding a lot, but we were able to stop it. 

It has been 7 days, and suddenly the girl stopped eating and stopped gaining weight.  I took her to the vet today and she has a severe heart murmur.  I just couldn't have her put to sleep!  I am not a "breeder", just someone who ADORES puppies.  This is all so heartbreaking though.  I am getting Tiffany fixed when she is done nursing.  I don't know how to deal with the sadness of losing one pup, and now another on the verge of dying!  The sick baby girl will not nurse at all, and the vet showed me how to tube feed.  I am terrible at it, and so afraid she is going to die everytime I have to do it.  Maybe I should have had her put to sleep, but I couldn't do it!!  I love these babies before they are ever even born. 

Any advice on dealing with these sad emotions, or any help on tube feeding would be so apprecietated.

:(

Teetah, I feel desperately sorry for your situation. It must be truly awful. There are people on this Forum who will be able to advise you on tube-feeding, how it's done, what milk to use, etc. You have come to the right place for practical advice. I do hope your pups survive.

But, if you own a bitch who has had a litter, you are a 'breeder'!

I know the feelings are strong at the moment, it is difficult to see this little one struggle. Keep your head up high.... A few questions to ask yourself, do you want to see this little one suffer for its lifetime, are you ready to offer a permanent home to a fully grown one with a severe heart mumur. Are you really ready for all of this. It is hard for one to see a puppy suffer, but you have to look beyond that, quality of life, and more.  Research and see what it is like to own a dog with a sever heart mumur, if in the end you still want to press on than you have made the correct decision, if you decided that it may not be the best thing, again the best decision, but most of all your decision will be well informed and made for the right reasons and not the "from the heart" reasons.
Think long and hard about your decision, always remember, it is no ones fault, it does happen, you will always remember this little one no matter what....
Best Of luck to you, either way I hope all goes well for you!
