64 day pregnant dog???

Sounds like she's readying herself to give birth. One day late is nothing to fret about. Can you feel pups in her abdomen? I found that if my dog was lying down and I rested my hand on her tummy, little bodies would reach up under the skin.

Your vet is right about not using ultrasound this late, but in any case it's not all that accurate. Not all that many vets have first-hand experience of pregnancy and birth in dogs, so yours is quite rightly going by the book, but your bitch hasn't read it. You know your own animal better than anyone, so if in your estimation she appears distressed, take her to another vet. They sometimes have a condition called uterine inertia, when labour starts and then stops, and a simple injection sorts it. Or, as you surmised, there might be one big pup getting in the way. But most births go well, so probably by now you are watching her suckling her new litter!

 

The mucus sounds quiet normal for a pregnancy, that's as long as it's clear and clean with no blood.
If you have just a singleton inside her there may not be the right amount of hormones to get her going into labour. Another worry is that if you have only a single puppy or two, that maybe the puppy has grown too large to be passed naturally.
Has she done any scratching or looking for anywhere to make a nest ?
Of course she may not have conceived on the day she was mated, it may have happened a day of two later.
Was the dog that you used a proven sire, has he mated and had puppies before?
You may be more stressed than she is. As long as she is not having contractions with no results, and seems reasonably settled, she is probably ok.
Could she be panting just because she is hot, do you have a heater on for her already (not required yet though). does she live indoors with you and has she a heavy coat, she may just be feeling too warm.

If you are at all worried about her you must see your vet or a different one.

I think that it dose not matter how many litters you may have produced or how many years experience you may have, a caring owner always worries at this stage.
Unfortunately not many vets have had the privilege to be present at a normal whelping and they can only advise on what they have read/studied.

Please do keep us informed how things go. Good luck.

 

How is the pregnancy progressing, is there any further news yet ?

 

Thank you for your reply.
I hope the news is ok. Keep in touch.
