Ok...a little back info... We have been in to showing, sled training and breeding for nearly 25yrs now. We have had false pgs in the past and it was no big deal really. BUT.... About 4yrs ago my dad started feeding a new food. Since then we have had 1 successful breeding and litter. the food is the only thing we can pin it on. We have done vaginal culutres, brucella testing, pregesterone testing to time breedings, A.I.s, smears....about everything we could do to find a reason or help get a good breeding. Our females even "refused" breeding for the most part. The only breeding we did get took 2 people to hold the female! Even the heat cycles have been "wrong" for years. The food my dad was feeding contained farm-raised salmon. Farm raised salmon is feed hormones so that, if they get loose, they cannot reproduce. A month after changing foods we had a female come into season. She accepted 3 breedings easily. This encouraged us. I would not have believed the food could affect them so much but, it seemed like this was the case. The last time we tried to breed this female she was wretched, she refused to stand, she did acrobatics we'd never seen before! Her last due date (based on 62days) is today. Last week she lost all her belly hair, her mammary glands began to look fuller and she was nesting. Sunday she didn't eat and it looked like she was thinking of going into labour. 24hrs later, nothing. She actually came out of her whelping pen and started to play with the other dogs. Now we are very discouraged. The stud is proven, he has had litters with quite a few females so far. Again....I have a but! Our litter about 5yrs ago we actually did a "planned" c-section. The female was looking barely preg, acting almost normal and was at 65 days. We X-rayed and sure enough there were pups. It was Dec 22nd, the vet I work for was going away for Christmas and the vet who was on-shift most of the holiday time at our local emerg clinic was one I knew but, had never done surgery on my dogs. So, we decided to do her c-section the next day. the long and short.... Experiences with overdue? With falsies? Breeding issues. We have discussed these issues with many of our Siberian Husky friends. They are as stumped as us!
