So, the first trail breeding, which happened in Skwentna, was between Wifi and Tramp. It turns out that this breeding did not 'take'. We are able to determine that with complete certainty due to the timing of the birth (pups conceived on this date would not have been viable on the date her litter was born).
It was later determined that Gerry Sousa's main stud dog bred Boo in Skwentna. Gerry informed me of this when I saw him in McGrath.
The next breeding was on the trail between Finger Lake and Rainy Pass between Boo and Wifi. As I had an uneven number of girls and boys on the team, I was forced to put an extra piece of gangline in or run a male and female together. After this breeding I decided to run Wifi and Boo together, since the 'damage' had already been done.
Again Boo and Wifi, this time in some overflow between Rohn and Nikolai.
Boo and Wifi on the way to Nikolai.
And lastly, Boo and Wifi on the trail between Ophir and Cripple
Boo is very definitely pregnant. Her puppies are due in 3 days on May 7th.
DNA testing is relatively easy and 'relatively' inexpensive these days, so it will be done to determine who is actually the father of Boo's puppies. And yes, dogs can have puppies in one litter that are sired by different dogs!
Wifi reports that he REALLY enjoyed the Iditarod this year! =)
