I have a female mastiff who was surgically inseminated on May 28th. Yesterday (7-2), we had a sonagram. The vet could not find anything. I was wondering how many of you have had sonagrams come back negative and still had puppies? Also, how many of you have had success with IUI? I have been researching mastiffs and breeding for over 3 years, completed the pre-breeding testing on my female, researched and found a stud with completed testing, and still feel like I have so much to learn. The stud owner has been wonderful, but I am looking for others opinions as well. Thanks for your time.
As I said, usually the sonogram can pick up the little vesicles containing the embryo and fluid, etc all lined up in the uterus at around 20 days. 35 days, and nothing to see on the sonogram would definitely mean no pregnancy with my breed, plus I would also be able to tell, just by looking at the dog. I think it may be different for a huge dog, but that'a guess. I wish you luck, and hope the sonogram is wrong.
I am new to this, but we had a litter last summer with the same bitch. At about 48 days the vet said she was not pregnant after palpitating her. She tends to hide the pups under her rib cage. I was hoping with a sonagram it would tell us something. She appears to be pregnant, morning sickness, growing belly, swollen nipples, and very tired. But she has also had a false pregnancy with milk and all. I just would like to know for sure. I guess I will just have to wait. I have heard from another mastiff breeder that sonagrams in this breed are useless because they are too big. I was just wanting to get some other opinions. Thanks
Sorry, I hit the wrong button. Yes, we did progesterone testing before the IUI. The vet suggested if I felt any question in 2 weeks at 49-50 days to bring her in for an x-ray.
When a sonagram is completed on a dog, do they lay them on their backs, or on their sides, or standing? I am asking because my female was on her back and the other breeder of mastiffs I know said her vet does it on her side or standing? I am confused.
I would definitely question a vet performing a sonogram on a Mastiff, with her lying on her back. First of all, it would be very stressful, and secondly, the pups would fall back towards the spine. Mine are always done standing up, and the reason is because they hang down, and you have a better chance of seeing them. I do have a Boxer breeder friend who I was talking to today and she said she actually took one of her dogs in, and the sonogram was not showing anything. A week later, she took her back, and the pups could clearly be seen. Of course she couldn't remember the date of gestation, but she thought it was around 25 days. I would try again, perhaps in another week, and I would have the sonogram taken by a specialist, since they are very hard to read. Good luck, and let us know what you find out.
I have owned Mastifs and Bullmastiffs for over 30 years. It is very difficult to determine a pregnancy in these breeds. The pups travel into the rib cage until very far into the pregnancy and it is difficult to palpate or do a sonagram . These breeds also have problems with uterine inertia when having a large litter as some of the pups are so far up in the rib cage and the bitches become exhausted.I have an x-ray done a week before the due date to get an idea of how many pups to expect, if the x-ray plate is whited out and it is impossible to see much then it is a very large litter and experience has taught me it is better to do a planned c-section rather than letting the bitch go into labor , become exhausted and then possibly loose both mother and pups before an emergency surgery can be done.I had two vets insist a bitch was not pregnant, a week later she had 10 pups. These are difficult breeds for a novice and I recomend finding an experienced breeder to mentor.
